Concise scientific profiles covering the biological role, mechanism and principal areas studied for each peptide. Every profile distinguishes between established applications, emerging human evidence and predominantly preclinical research, because not every peptide has the same evidence base or regulatory status.
The Peptide Library is an educational scientific resource. Inclusion does not mean that a peptide is approved, supplied or appropriate for clinical use in Thailand.
BPC-157 is a synthetic 15-amino-acid peptide derived from a protective protein sequence identified in gastric tissue. It is being investigated for its potential effects on tissue repair, blood-vessel formation and inflammatory signalling.
Tendon and ligament recovery, musculoskeletal injury, wound healing and gastrointestinal tissue protection. Evidence remains predominantly preclinical, with very limited human data.
TB-500 is a synthetic peptide related to thymosin beta-4, a naturally occurring protein involved in cell migration, tissue remodelling and wound repair.
Soft-tissue recovery, wound healing, inflammation and repair following muscle or tendon injury. Evidence for TB-500 itself is predominantly preclinical, and it has no established clinical indication.
KPV is a three-amino-acid peptide derived from alpha-melanocyte-stimulating hormone. It is studied for anti-inflammatory effects without the pigment-producing activity associated with the parent hormone.
Inflammatory bowel conditions, intestinal-barrier dysfunction, inflammatory skin conditions and local immune regulation. Evidence is largely derived from laboratory and animal studies.
CJC-1295 is a synthetic analogue of growth-hormone-releasing hormone, while ipamorelin activates the ghrelin receptor. Together, they are intended to stimulate the body's pulsatile release of growth hormone and increase downstream IGF-1 signalling.
Growth-hormone secretion, body composition, recovery and sleep-related outcomes. Human evidence for the combination is limited, and it is not an established treatment for general anti-ageing or body-composition management.
AOD-9604 is a modified fragment of human growth hormone corresponding to part of its C-terminal region. It was developed to investigate whether some of growth hormone's effects on fat metabolism could be separated from its growth-promoting activity.
Obesity, fat metabolism and body-fat reduction. Clinical development for obesity did not demonstrate sufficiently convincing efficacy, and AOD-9604 has no established therapeutic indication.
Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone. It stimulates the pituitary gland to release endogenous growth hormone, which subsequently increases IGF-1.
Reduction of excess abdominal fat in adults with HIV-associated lipodystrophy. It is approved for this specific indication in the United States and is not approved there as a general weight-loss treatment.
PEG-MGF is a pegylated synthetic form related to mechano growth factor, an IGF-1 splice variant associated with the local cellular response to mechanical stress and muscle injury.
Muscle repair, regeneration and adaptation following mechanical loading. Research is predominantly preclinical, with no established therapeutic indication or adequate human safety evidence.
IGF-1 LR3 is a modified, longer-acting analogue of insulin-like growth factor 1. It is designed to remain biologically active for longer and interact less strongly with IGF-binding proteins than natural IGF-1.
Cell growth, muscle development, tissue repair and metabolic signalling. IGF-1 LR3 is an experimental research compound and should not be confused with approved pharmaceutical forms of recombinant human IGF-1.
GHRP-2 and GHRP-6 are synthetic growth-hormone secretagogues that activate the ghrelin receptor, stimulating the release of endogenous growth hormone. GHRP-6 is also associated with a more pronounced effect on appetite.
Growth-hormone release, growth-hormone deficiency research, appetite regulation and body-composition outcomes. Neither peptide has an established indication for routine anti-ageing, recovery or physique management.
MOTS-c is a mitochondrial-derived peptide encoded within mitochondrial DNA. It is involved in cellular stress responses and the communication between mitochondrial function and whole-body metabolism.
Insulin sensitivity, glucose metabolism, exercise adaptation, metabolic health and healthy-ageing biology. Most therapeutic evidence remains preclinical.
Retatrutide is an investigational peptide that activates three metabolic hormone receptors: GLP-1, GIP and glucagon. This combined mechanism is being developed to influence appetite, energy balance and glucose metabolism.
Obesity, overweight, type 2 diabetes and obesity-related metabolic disease. Retatrutide remains under clinical investigation and should not be presented as an approved medicine unless its status changes in the relevant market.
PT-141, also known as bremelanotide, is a melanocortin-receptor agonist that acts through central nervous system pathways involved in sexual desire and arousal.
Bremelanotide is approved in the United States for acquired, generalised hypoactive sexual desire disorder in certain premenopausal women. Other proposed uses, including use in men or for sexual-performance enhancement, are not part of that approved indication.
Kisspeptin is a naturally occurring neuropeptide that activates the reproductive hormonal axis by stimulating gonadotropin-releasing hormone. It plays an important role in puberty, fertility and reproductive function.
Fertility treatment, reproductive-hormone assessment, hypothalamic amenorrhoea, hypogonadism and aspects of sexual and emotional processing. Its therapeutic applications remain investigational.
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma and other body fluids. It is associated with extracellular-matrix signalling, tissue remodelling and wound-repair processes.
Skin quality, visible signs of ageing, wound healing and hair-growth support. Topical cosmetic use is substantially better established than injectable or systemic use, for which human safety data remain limited.
Thymosin alpha-1 is a naturally occurring 28-amino-acid peptide involved in immune regulation, particularly the development and activity of T cells and other components of the cellular immune response.
Immune modulation, chronic infection, immune dysfunction and adjunctive support in selected clinical settings. It is authorised in some countries for specific indications but does not have universal regulatory approval.
Selank is a synthetic peptide analogue derived from tuftsin, a naturally occurring immune-related peptide. It has been investigated for interactions with neurotransmitter systems involved in anxiety, cognition and emotional regulation.
Anxiety, stress resilience, attention and cognitive performance. Available evidence is limited and largely originates from regional studies, with insufficient validation for a broadly established clinical indication.
Semax is a synthetic peptide derived from a fragment of adrenocorticotropic hormone, modified to remove hormonal activity while retaining proposed neuromodulatory effects.
Cognitive function, attention, neuroprotection and recovery following neurological injury or stroke. Evidence is geographically limited, and its regulatory status differs between countries.
Delta sleep-inducing peptide, or DSIP, is a naturally occurring nonapeptide originally investigated for its possible role in sleep and neuroendocrine regulation.
Sleep regulation, stress response, pain modulation and neuroendocrine function. Findings have been inconsistent, and there is no established clinical indication.
Pinealon is a synthetic tripeptide composed of glutamic acid, aspartic acid and arginine. It has been investigated as a short peptide capable of influencing neuronal stress responses and gene regulation.
Cognitive ageing, memory, neuronal protection and recovery from neurological stress. Published evidence is limited, and there is no widely established therapeutic indication.
Epitalon is a synthetic tetrapeptide based on peptides associated with the pineal gland. It has been studied for possible effects on circadian biology, cellular ageing and telomere-related mechanisms.
Ageing biology, sleep and circadian regulation, oxidative stress and telomere research. Evidence is limited and does not establish Epitalon as a clinically proven longevity treatment.
Humanin is a mitochondrial-derived peptide involved in cellular stress responses. Experimental research suggests that it may help regulate cell survival, metabolic signalling and protection against certain forms of cellular injury.
Healthy-ageing biology, metabolic dysfunction, neurodegeneration and cellular resilience. Research remains predominantly preclinical, with no established therapeutic indication.
