Peptide guides
20 plain-English guides covering mechanism, research areas and health benefits — grouped by goal.
Tissue Recovery & Repair
Peptides studied for soft-tissue healing, gut integrity and joint recovery.
BPC-157
Body Protection Compound-157
A synthetic pentadecapeptide derived from a protein in gastric juice, widely studied in animal models for soft-tissue healing, gut integrity and blood-vessel growth.
TB-500
Thymosin β4 fragment
A synthetic version of a region of Thymosin Beta-4, a naturally occurring protein involved in cell migration and tissue repair, studied for recovery and flexibility.
Growth-Hormone Axis
Secretagogues and GHRH analogues investigated for the body's natural growth-hormone rhythm.
CJC-1295 (No DAC)
Mod GRF 1-29
A short-acting GHRH analogue that produces a clean, brief growth-hormone pulse closely mirroring the body's natural rhythm.
CJC-1295 DAC
A long-acting GHRH analogue with a Drug Affinity Complex that extends its half-life to days, studied for sustained support of the growth-hormone axis.
Ipamorelin
A selective growth-hormone secretagogue that gently nudges the pituitary to release growth hormone in natural pulses, studied for recovery, body composition and sleep.
Sermorelin
One of the earliest GHRH analogues, a truncated fragment studied for decades as a gentle way to support the body's own growth-hormone production.
Tesamorelin
A stabilised GHRH analogue best known in research for reducing stubborn visceral fat while supporting the growth-hormone axis.
Metabolic & Weight
Incretin and metabolic compounds studied for appetite, glucose handling and body composition.
5-Amino-1MQ
A small molecule that blocks the enzyme NNMT, studied for boosting cellular NAD+ and metabolism, with interest in fat loss and muscle health.
HGH Fragment 176-191
AOD-9604 relative, GH frag
A small fragment of human growth hormone isolated for its fat-metabolism effects, studied for lipolysis without the broader actions of full growth hormone.
Retatrutide
An investigational "triple agonist" targeting three metabolic receptors at once, generating significant interest for weight and metabolic research.
Semaglutide
A well-known GLP-1 receptor agonist studied extensively for appetite regulation, blood-sugar control and weight management.
Tirzepatide
A dual GIP/GLP-1 receptor agonist that has reshaped metabolic research, widely studied for weight management and glucose control.
Mitochondria & Energy
Compounds explored for cellular energy production and exercise-mimetic effects.
MOTS-c
A mitochondrial-derived peptide that acts as a metabolic regulator, studied for energy metabolism, insulin sensitivity and exercise-like benefits.
SLU-PP-332
An experimental exercise-mimetic small molecule that activates ERR receptors to switch on endurance and fat-burning pathways, studied for metabolism and stamina.
SS-31
Elamipretide
A mitochondria-targeted peptide that protects the inner membrane lipid cardiolipin, studied for cellular energy, heart and age-related mitochondrial decline.
Longevity & Skin
Peptides researched for ageing pathways, skin quality and cellular maintenance.
Epitalon
Epithalon
A synthetic tetrapeptide studied for its effects on telomerase, circadian rhythm and the pineal gland, with longstanding interest in longevity research.
GHK-Cu
Copper Peptide
A naturally occurring copper-binding tripeptide celebrated in skincare research for collagen, wound healing and hair-follicle support.
Lifestyle & Wellbeing
Melanocortin-pathway peptides studied for pigmentation, libido and mood.
Melanotan 2
A synthetic analogue of the body's α-MSH hormone, studied for stimulating melanin (tanning) and, secondarily, appetite and libido effects.
PT-141
Bremelanotide
A melanocortin-receptor agonist studied for sexual arousal and desire, acting through the central nervous system rather than the vascular system.
Immune Support
Peptides investigated for immune signalling and T-cell function.
