Consider it a reference document for identifying compounds available for a specific area of research, or perhaps a concise refresher on what various peptides do and why they are important to contemporary science.
One of the most active frontiers in peptide science is research into growth hormone. The ability of the pituitary gland to orchestrate growth hormone secretion and its stimulatory or inhibitory influence on metabolism, body composition, tissue maintenance, and even ageing has been examined for decades. UK-based laboratories can Shop Cartalax peptide in UK through the regional Pharma Lab storefront. These peptides operate through multiple mechanisms to stimulate, modulate, or mimic the body's natural GH pathways, thereby providing researchers with refined tools for investigating these complex biological systems. Pharma Lab provides a full spectrum of GH-associated peptides, with each compound serving a distinct research purpose.
CJC-1295 DAC is a synthetic GHRH analogue that incorporates a Drug Affinity Complex, which substantially extends its biological half-life. The DAC moiety attaches to albumin in the blood, slowing clearance and allowing effective peptide concentrations to persist over extended periods. This makes it a uniquely positioned research tool for studying sustained GH stimulation and the corresponding IGF-1 response profiles that emerge from prolonged activity.
The non-DAC version of CJC-1295 mimics GHRH but does not include the albumin-binding complex, resulting in a shorter duration of action and a more pulsatile release of growth hormone. Due to its shorter half-life, it more closely replicates endogenous GHRH signaling and is especially relevant in studies investigating circadian GH release patterns or in comparison with the sustained-release profile of the DAC variant across pre-clinical models.
GHRP-2 is a synthetic hexapeptide that functions as an effective growth hormone secretagogue through its agonist activity at ghrelin receptors. It simultaneously stimulates GH release from the pituitary gland and modulates regulators of appetite and cortisol secretion. GHRP-2 is used in the study of ghrelin-GH axis relationships how peripheral hunger signals intersect with somatotropic activity. It is often regarded as the reference compound in secretagogue comparisons due to its strong GH-releasing potency.
GHRP-6 is one of the earliest growth hormone-releasing peptides described in the literature. It works through ghrelin receptors to stimulate GH secretion in a manner similar to GHRP-2 but produces a significantly greater appetite-stimulating effect. This property makes GHRP-6 particularly useful in research focused on the interaction between GH release, feeding behaviour, and metabolic regulation. It also influences cortisol and prolactin levels, adding another dimension of interest for researchers studying hormonal interactions.
Hexarelin is a synthetic growth hormone secretagogue that has attracted special interest for effects extending beyond simple GH release. Studies have explored its influence on cardiac function, lipid metabolism, and myocardial tissue, suggesting potentially cardioprotective and pro-angiogenic properties. This dual action — stimulating GH secretion while simultaneously acting on cardiac receptors — positions Hexarelin as a uniquely valuable compound for bridging the typically separate disciplines of endocrinology and cardiovascular science.
Among GH secretagogues, Ipamorelin is uniquely selective. It stimulates growth hormone release with minimal increases in cortisol and prolactin — an attribute that makes it particularly useful in studies where the objective is to produce the cleanest possible GH response without confounding hormonal changes. Ipamorelin is often selected by researchers investigating body composition, bone density, or the isolated effects of elevated GH for precisely this reason.
Sermorelin is the biologically active fragment of GHRH, comprising the first 29 amino acids of the native 44-amino-acid hormone. It remains one of the most studied GHRH analogues and continues to serve as a foundational compound in GH deficit research, paediatric endocrinology, and anti-ageing studies. Sermorelin activates the pituitary to produce and release growth hormone through the natural regulatory pathway, thereby preserving the body's endogenous feedback mechanisms.
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone that has been the subject of considerable research into its ability to reduce visceral adipose tissue accumulation, particularly in the context of HIV-associated lipodystrophy. Tesamorelin exerts a significant effect on fat metabolism by specifically targeting abdominal fat deposits through stimulation of pituitary GH release and IGF-1 production without altering other adipose tissue stores.
Although MK677 is frequently discussed alongside peptides, it is technically a non-peptide compound — an orally bioavailable growth hormone secretagogue. As a ghrelin receptor agonist, it produces prolonged GH and IGF-1 stimulation. From a research perspective, MK677 is commonly used to examine the long-term effects of sustained GH elevation, sleep quality, nitrogen balance in the context of disuse muscle wasting, and the potential to counteract mild age-related GH decline.
HGH191AA is recombinant human growth hormone, a protein comprising the full 191 amino acid sequence. Structurally, it is identical to the growth hormone naturally produced by the pituitary gland. This compound is used in research settings where investigators require the complete GH molecule rather than a secretagogue or fragment, facilitating direct evaluation of GH receptor activation, tissue repair signaling, and the full range of somatotropic effects.
This peptide corresponds to amino acids 176 through 191 of the C-terminal portion of the growth hormone molecule. Research has characterized this fragment as the region of GH responsible for its lipolytic, or fat-metabolizing, effects. Importantly, the 176-191 fragment does not appear to influence blood glucose or stimulate cell growth in the manner of full-length GH, making it a selective tool for examining lipid metabolism independently of the other biological actions that complete growth hormone produces.
One of the foundational principles in biology is how the body repairs damaged tissue, closes wounds, and resolves inflammation. The peptides that influence these processes have become indispensable tools in research laboratories studying everything from sports injuries to chronic inflammatory diseases and degenerative conditions.

This broad regenerative profile has made it a valuable addition to laboratories working on wound healing and gastrointestinal integrity.
TB500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4, which regulates cell migration, angiogenesis, and wound repair. Its role in promoting the healing of injured muscle, skin, and connective tissue through the upregulation of actin is well documented. It remains one of the most studied compounds in recovery and regeneration protocols, particularly valued for its anti-inflammatory properties.
Mechano Growth Factor is a variant of IGF-1 that is expressed in muscle tissue following mechanical stress such as exercise or injury. It plays a critical role in the activation of satellite cells — the muscle stem cells involved in repair and growth. MGF is commonly used by scientists studying the early-stage repair processes that precede muscle regeneration, particularly during post-exercise recovery, injury repair, and hypertrophy signaling.
PEG-MGF is a PEGylated version of Mechano Growth Factor, where the addition of a polyethylene glycol chain significantly extends the peptide's half-life. This modification enables researchers to investigate sustained MGF activity over longer periods and to understand how prolonged activation of satellite cell activity and muscle-repair signaling differs from the transient bursts observed with native MGF. This is particularly beneficial for research protocols requiring extended exposure windows.
GHK-Cu is a naturally occurring copper peptide complex investigated for its roles in collagen synthesis, skin remodelling, and wound healing.

Produced as a topical peptide designed for surface-level application, Matrixyl serves as a practical research tool for studies in skin biology and transdermal peptide delivery.
The complexity of the immune system makes it perhaps one of the most challenging — and rewarding — areas within biomedical research. Peptides that serve as mediators of immune function, regulators of T-cell activity, or antimicrobial agents are providing researchers with the ability to explore areas ranging from age-associated declines in immunity to antimicrobial resistance. Pharma Lab provides a carefully curated selection of immune-relevant peptides, each supported by extensive scientific literature and manufactured to exacting standards.
Thymosin Alpha-1 is a 28-amino-acid peptide originally identified as a secretion of the thymus gland, centrally involved in the regulation of immune function. Its primary mechanisms of action include inducing T-cell maturation, stimulating antigen presentation, and increasing cytokine production. Studies have explored its applications in chronic infections such as hepatitis B and C, autoimmune diseases, and as an adjunct in cancer immunotherapy research.
Thymalin is a thymus-derived bioregulator peptide studied for its immunoregulatory properties and its ability to restore function to an ageing or diminished thymus-dependent immune system. As the thymus naturally shrinks with age, the body's capacity to produce new T-cells declines. Thymalin is being investigated to determine whether bioregulatory peptides can slow or partially reverse this process, potentially restoring a more responsive immune profile in ageing subjects.
LL-37 is a cathelicidin-derived antimicrobial peptide and the sole member of this family found in humans, playing an essential role in innate immunity. It demonstrates activity against a wide range of pathogens, including bacteria, viruses, and fungi. Beyond its direct antimicrobial properties, LL-37 exerts diverse effects on the inflammatory response and wound healing, making it a versatile research tool for laboratories studying innate immunity and tissue repair simultaneously.
Vilon is a synthetic thymic dipeptide studied at the gene level as an immunomodulator. It is known to induce epigenetic changes that may enhance or restore expression of genes regulating the immune response. Vilon is a more recently established compound in the field of bioregulator peptides, with ongoing studies investigating its potential to restore immune function and reverse the immune decline associated with ageing.
Bronchogen is a bioregulator peptide under investigation specifically for respiratory tissues. Research has prioritized its potential to support lung tissue repair and modulate immune function within the pulmonary system. With a tighter research focus than many other immune peptides, Bronchogen is particularly relevant for laboratories studying pulmonary health, chronic respiratory conditions, and the regenerative capacity of lung tissue.
Vasoactive Intestinal Peptide is an extensively studied 28-amino-acid neuropeptide with wide-ranging biological activity. Research has connected VIP to neuroprotection, vasodilation, anti-inflammatory processes, and immune regulation. It is examined in the context of autoimmune diseases, neurodegenerative conditions, and inflammatory disorders. The ability of VIP to modulate both the nervous and immune systems simultaneously makes it a uniquely versatile peptide in the laboratory setting.
How the body stores and expends energy at the molecular level, and how energy balance is regulated, represent some of the most relevant research topics in modern medicine. Peptides that can modulate lipid metabolism, appetite signaling, cellular energy sensing, and mitochondrial function are opening new avenues for investigating obesity, metabolic syndrome, and the fundamental biology of energy balance. For laboratories working in this space, Pharma Lab supplies the following compounds.
5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase, an enzyme involved in cellular energy expenditure and fat metabolism. NNMT inhibition has been shown to stimulate energy metabolism in fat cells, promoting a shift toward a metabolically active, brown fat-like state from the default energy-storing role. This is why 5-Amino-1MQ draws particular attention in studies of obesity and related metabolic conditions, primarily at the cellular level.
AOD-9604 is a synthetic analogue that preserves the lipolytic (fat-reducing) actions of growth hormone without producing biological effects on blood sugar or cell proliferation. Its potential as an anti-obesity agent targeting lipolysis through a distinct mechanism has been the subject of investigation. It is studied for its ability to promote the breakdown of fat while simultaneously inhibiting the formation of new fat, all without the hormonal effects associated with full-length growth hormone.
AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) is an AMP-activated protein kinase activator that has earned the description of "exercise mimetic" in research literature. Activation of AMPK by AICAR triggers a cascade of biological pathways related to glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. This compound serves as an important research tool for studying the molecular mechanisms underlying exercise adaptation and metabolic regulation.
The AMP-activated protein kinase pathway serves as a master regulator of cellular energy homeostasis, and AMPK activator peptides specifically target this pathway. AMPK is activated when cellular energy levels drop, restoring balance by enhancing catabolic pathways while inhibiting anabolic processes. Research with AMPK activators explores how this fundamental energy sensor can be modulated to influence fat metabolism, glucose handling, and overall metabolic health.
FTPP Adipotide is a peptidomimetic that targets the blood vessels supplying white adipose tissue. Its role in inducing programmed cell death by disrupting blood flow to fat tissue has been studied extensively. Uniquely, Adipotide targets fat reduction by eliminating fat cells rather than merely shrinking them, making it fundamentally different from other metabolic interventions in the field of obesity research.
Tesofensine was originally researched as a neurological agent but has since been shown to produce notable effects on appetite suppression and weight reduction. Research has explored its effects on central nervous system hunger and satiety signaling, making it relevant to both neuroscience and metabolic research. Its mechanism of action as a triple reuptake inhibitor positions it at an interesting intersection of multiple research disciplines.
MOTS-C is a 16-amino-acid mitochondrial-derived peptide encoded within the mitochondrial genome — one of only a few peptides known to originate outside of nuclear DNA. Studies have particularly highlighted its role in metabolic homeostasis, insulin sensitivity, and exercise physiology. MOTS-C appears capable of coordinating cellular glucose processing and metabolic stress responses, establishing connections between mitochondrial signaling and whole-body energy coordination that are still being explored.
The brain remains the most complex organ in the body, and the peptides that interact with it — modulating neurotransmitter release, synaptic plasticity, neuroprotection, and circadian rhythms — are among the most compelling research tools available. This category includes peptides investigated in the context of cognition enhancement, mood regulation, anxiety reduction, sleep architecture, and neuroprotection. Pharma Lab provides the following neuropeptides for research purposes.
Selank is a synthetic adaptation of tuftsin, a naturally occurring immunopeptide, and has been studied for its anxiolytic and nootropic properties. It has attracted research interest primarily for its modulatory effects on the GABAergic system and its influence on serotonin metabolism. Research suggests it may alleviate anxiety without producing sedative or addiction-related effects. It is also explored for its immunomodulatory characteristics, placing it at a unique intersection between neuroscience and immunology.
Semax is a synthetic analogue of adrenocorticotropic hormone investigated for neuroprotective and cognitive-enhancing properties. Studies have demonstrated its ability to increase brain-derived neurotrophic factor, an important protein for synaptic plasticity and memory formation. Research has also focused on Semax in the context of stroke recovery and its effects on dopaminergic and serotonergic pathways.
DSIP is a naturally occurring neuropeptide originally discovered for its ability to induce slow-wave (delta) sleep. Beyond modifying sleep architecture, DSIP has been studied for its capacity to modulate the stress response, influence pain perception, and regulate circadian rhythms. It serves as a useful experimental tool for researchers investigating the neurobiology of sleep and its relationship to physiological recovery processes.
P-21 is a synthetic peptide based on the sequence of ciliary neurotrophic factor, investigated for its connection to neurogenesis — the formation of new neurons. Research has explored P-21's potential to promote memory acquisition and learning, and interest is growing in its applications as an experimental model for neurodegenerative processes that may resemble features observed in chronic conditions such as Alzheimer's disease. Its ability to promote neural growth without the systemic effects of full-length CNTF makes it a valuable research tool.
Pinealon is an oligopeptide bioregulator that acts primarily on the pineal gland — the region of the brain responsible for melatonin production and circadian rhythm regulation. Studies have examined its effects on sleep quality, neuroprotection, and biological clock regulation. Pinealon offers a targeted research approach for laboratories investigating the mechanisms through which pineal function declines with ageing and the consequences of that decline for neurological health.
Orexin A is a hypothalamic neuropeptide fundamentally involved in regulating arousal, sleep, and appetite. Much of the research into Orexin A stems from its association with narcolepsy — a condition in which orexin-producing neurons are lost. Beyond sleep-wake regulation, Orexin A has been investigated for its contributions to reward-seeking behaviour and energy expenditure, serving as an integrating signal that connects metabolic and arousal pathways in the brain.
Nicotinamide adenine dinucleotide is a coenzyme present in all living cells, playing a key role in energy metabolism, DNA repair, and sirtuin activity — proteins linked to cellular ageing and stress responses. NAD+ levels naturally decline with age, and questions have emerged regarding whether restoring these levels might ameliorate aspects of mitochondrial dysfunction, provide protection against neurodegeneration, and potentially influence certain features of the ageing process.
Adamax is a research nootropic peptide explored for its potential to enhance cognitive performance in areas related to memory, focus, and information processing. Its mechanisms of action through neural signaling pathways remain under active investigation. Adamax represents a relatively recent area of peptide research with growing scientific interest, and is relevant to laboratories examining compounds that might modulate cognitive function through novel pathways.
Protirelin is an analogue of thyrotropin-releasing hormone, a tripeptide secreted by the hypothalamus that triggers the secretion of thyroid-stimulating hormone. Beyond its role in endocrine function, TRH has also been studied as a potential neuromodulator, with suspected involvement in depression, consciousness, and central nervous system arousal. Protirelin research spans endocrinology, neuroscience, and psychopharmacological investigation.
Ageing is an accumulation of processes — telomere shortening, mitochondrial dysfunction, oxidative damage, and senescent cell burden. Peptides that target each of these specific mechanisms are equipping researchers with tools to investigate whether ageing can be slowed or modified by intervening at the molecular level. Pharma Lab offers the following peptides for laboratories focused on gerontology and cellular health.
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide researched for its potential to activate telomerase, an enzyme that helps regulate telomere length at chromosome ends. Since telomere shortening is a classical marker of cellular senescence, research on Epithalon explores whether telomerase activation could prolong lifespan at the cellular level. Additional studies have examined its ability to influence pineal gland function and melatonin production.
FOXO4-DRI is a senolytic peptide that directly triggers selective apoptosis of senescent cells — non-dividing cells that secrete inflammatory signals affecting surrounding tissue. By disrupting the FOXO4-p53 interaction, this peptide promotes the death of senescent cells while sparing healthy cells. FOXO4-DRI research represents one of the leading frontiers in rejuvenation science, where the removal of damaged cells may contribute to tissue-level restoration.
Humanin is a mitochondrial-derived peptide studied for its cytoprotective potential. Research has focused on defining its capacity to protect cells against various forms of stress-induced apoptosis, with particular interest in neurodegenerative disorders such as Alzheimer's disease. The protective effects of Humanin on stressed cardiac cells have also generated interest in cardiovascular ageing research.

Research into its potential benefits for cartilage regeneration and joint health has been particularly relevant to ageing-related musculoskeletal decline. Cartalax provides a focused research tool within the broader landscape of ageing science, specifically for laboratories investigating osteoarthritis, joint degeneration, and cartilage biology.
SNAP-8 (acetyl octapeptide-3) is a peptide investigated for its effects on neuromuscular signaling at the junction between nerve endings and muscle fibres. It has been studied for its potential to modulate the SNARE complex involved in neurotransmitter release, which in turn triggers muscle contraction. In the context of dermatological research, SNAP-8 has attracted attention for its potential to diminish expression lines.
L-Glutathione is a tripeptide composed of three amino acids — glutamine, cysteine, and glycine — that functions as the most abundant intracellular antioxidant in the body. Research has identified its key roles in free radical neutralisation, liver detoxification support, and cellular redox balance. Studies also investigate its involvement in skin health and the association between declining glutathione levels and conditions observed with advancing age.
At every stage of reproductive biology — from the hypothalamic signals that trigger the onset of puberty to the hormonal cascades regulating fertility and sexual function — peptides perform central roles. Research in this domain encompasses endocrinology, reproductive medicine, and behavioural neuroscience. All peptides listed below are supplied by Pharma Lab exclusively for research and laboratory use.
PT-141 is a melanocortin receptor agonist being investigated for its effects on sexual arousal and desire. Unlike most other approaches, PT-141 acts through the central nervous system, stimulating melanocortin receptors in the brain rather than operating through vascular mechanisms. Investigation has been conducted for both males and females, particularly in relation to hypoactive sexual desire disorder.
Kisspeptin is a hypothalamic peptide that initiates the signaling cascade for releasing reproductive hormones through stimulation of GnRH. It has been demonstrated to act as a master regulator of puberty onset and fertility, with research aimed at understanding its role in reproductive pathophysiology. Kisspeptin occupies the very top of a hormonal signaling hierarchy that governs reproductive function.
Gonadorelin is a synthetic version of gonadotropin-releasing hormone that stimulates the pituitary to release luteinizing hormone and follicle-stimulating hormone. It is used in research to investigate the hypothalamic-pituitary-gonadal axis and to study the regulation of fertility and the feedback loops that operate between reproductive hormones.
Triptorelin is a GnRH agonist which, despite initially stimulating pituitary hormone release, leads to desensitization upon continuous administration and subsequent decreases in LH and FSH production. This profile makes Triptorelin a useful investigative tool for examining hormone-dependent conditions, including those affecting prostate biology and the broader manipulation of the reproductive axis.
Human Chorionic Gonadotropin is a glycoprotein hormone produced during pregnancy, with structural similarity to luteinizing hormone. HCG is used in research for LH receptor activation, stimulation of testosterone production, and the study of various aspects of reproductive biology. It remains one of the most widely used compounds in fertility-related research.
Human Menopausal Gonadotropin contains both FSH and LH activity, which makes it a unique tool for ovarian stimulation studies, spermatogenesis investigation, and the experimental dissection of combined gonadotropin signaling effects on reproductive outcomes. This dual activity provides researchers with a single compound that activates both arms of gonadotropin biology.
Oxytocin is a neuropeptide hormone known for its involvement in social bonding, trust, emotional regulation, and stress reduction. Research extends well beyond reproduction to encompass anxiety, autism spectrum conditions, and the neurobiology of social behaviour. As both a hormone and neurotransmitter, Oxytocin is one of the most extensively studied peptides in behavioural neuroscience.
B7-33 is a single-chain relaxin receptor agonist with anti-fibrotic and cardiovascular effects. As a simplified analogue of relaxin-2, B7-33 allows researchers to study the actions of this normally two-chain hormone at the cellular level, both in vivo and in vitro, without the structural complexity associated with the natural hormone. This makes it particularly relevant to studies of tissue fibrosis and cardiovascular remodelling.
The biology of muscle growth has long fascinated researchers, and myostatin — a circulating protein that negatively regulates muscle size — has been one of the most actively studied targets since its identification. Peptides capable of inhibiting myostatin signaling or promoting muscle cell proliferation offer tools for understanding muscular dystrophy, sarcopenia, and the fundamental mechanisms of hypertrophy and atrophy.
ACE-031 is a soluble activin receptor type IIB, functioning as a decoy receptor that binds myostatin before the ligand can reach its target receptors on muscle cells. By intercepting myostatin signaling, ACE-031 effectively releases the natural brake on muscle growth. Research has explored its potential in muscle-wasting disorders such as muscular dystrophy and sarcopenia.
Follistatin 344 is a natural myostatin inhibitor that binds to and neutralizes myostatin, removing the inhibitory signal that limits muscle growth. Studies have primarily examined its role in muscle mass regulation, though research also extends to reproductive biology and metabolic function. Follistatin has been one of the most studied natural myostatin inhibitors for many years, establishing its importance in the field.
GDF-8, more commonly known as myostatin, is the key negative regulator of skeletal muscle mass. Scientists use recombinant forms of myostatin to study its signaling pathways and evaluate potential intervention points related to muscle wasting conditions. Understanding this natural growth brake — and how to modulate it — requires direct access to the myostatin molecule itself.
IGF-1 LR3 is the long-chain analogue of insulin-like growth factor 1, with a half-life significantly longer than native IGF-1. It is involved in cell growth and the inhibition of apoptosis, processes critical to muscle development and wound healing. The LR3 modification reduces binding to IGF-binding proteins, increasing the proportion of peptide available in its active form. Researchers working with anabolic signaling and tissue regeneration use IGF-1 LR3 for both its high potency and extended duration of action.
Melanogenesis — the biological process of pigment production in skin — is a fundamental area of research with implications for photoprotection, skin cancer prevention, and melanocyte biology. The following peptides act on melanocortin receptors to stimulate melanin production. Researchers should also note that GHK-Cu, KPV, Matrixyl, and SNAP-8, listed in their primary categories above, are all compounds relevant to dermatological research.
Melanotan 1, also referred to as afamelanotide, is a synthetic analogue of alpha-melanocyte-stimulating hormone with selective action on the MC1 receptor. Research interest centres on its biological effects in stimulating melanogenesis and enhancing skin pigmentation. It holds considerable potential as a photoprotective agent that may offer protection against UV-induced DNA damage at the molecular level, positioning it for use in both preventive dermatology and cancer prevention research.
Melanotan 2 is a non-selective melanocortin receptor agonist that activates several receptor subtypes beyond MC1R. This broader receptor profile results in a more complex research scope compared to Melanotan 1, with studies exploring effects on pigmentation, appetite regulation, and sexual function. By engaging multiple melanocortin pathways simultaneously, Melanotan 2 provides a tool for understanding the interactions and functions across different melanocortin receptor systems.
