The library
Peptide Library
Every profile covers what the compound is, what researchers use it for, commonly reported protocols, reconstitution, storage, and cautions.
5-Amino-1MQ
The oral metabolism molecule — a small NNMT inhibitor studied for raising cellular NAD+ and re-firing stubborn fat metabolism. Capsules, not needles.
AOD-9604
The fat-loss fragment — the tail end of growth hormone that keeps the fat-burning signal and drops everything else. No appetite suppression, no GLP-1 stomach.
BPC-157
The most-discussed recovery peptide — studied for tendon, ligament, muscle, and gut repair. The usual first compound for anyone training hard with nagging injuries.
Cagrilintide
The next weight-loss mechanism — an amylin analog that creates satiety through a completely different pathway than GLP-1, designed to pair with semaglutide.
CJC-1295 (no DAC)
A growth-hormone-releasing-hormone analog that prompts your pituitary to release its own GH in natural pulses — almost always paired with Ipamorelin.
DSIP
The sleep peptide — studied since the 1970s for deepening slow-wave sleep, which is where every other kind of recovery actually happens.
Epithalon
The telomere peptide — a four-amino-acid compound from Russian longevity research, studied for telomerase activation and sleep-hormone normalization.
GHK-Cu
A naturally occurring copper-binding peptide studied for skin quality, hair, wound healing, and tissue remodeling — the cosmetic-longevity workhorse.
Glutathione
The body's own master antioxidant — a tripeptide on every IV-therapy and med-spa menu, studied for detoxification, recovery, and oxidative stress.
IGF-1 LR3
A long-acting version of the body's primary growth signal — the compound experienced researchers graduate to once the GH-axis pair has done its work.
Ipamorelin
The cleanest of the GH secretagogues — triggers a growth-hormone pulse without meaningfully raising hunger or cortisol. CJC-1295's standard partner.
Kisspeptin-10
The upstream hormone switch — the signal that tells your brain to run the entire testosterone production line. Studied for natural hormonal support and desire.
KPV
A three-amino-acid fragment of a natural anti-inflammatory hormone — studied for gut inflammation, skin conditions, and calming an over-active immune response.
Melanotan-1
The gentler tanning peptide — more selective than MT-2, fewer side effects, and actually an approved medication in Europe for light-sensitivity disorders.
Melanotan-2
The tanning peptide — stimulates your own melanin production for a deep tan with a fraction of the sun exposure, plus the famous side benefit that launched PT-141.
MOTS-c
The "exercise in a vial" research peptide — encoded in mitochondrial DNA, studied for insulin sensitivity, endurance, and metabolic flexibility.
NAD+
Not technically a peptide — the cellular energy coenzyme itself, injected to restore levels that fall ~50% between youth and middle age. The longevity-circuit staple.
PT-141
The libido peptide — works through the nervous system rather than blood flow, which is exactly why it's studied where the little blue pill does nothing.
Retatrutide
The next-generation weight compound — a triple agonist (GLP-1 + GIP + glucagon) that posted the largest weight-loss numbers ever seen in trials. Still in phase 3.
Selank
A Russian-developed anti-anxiety peptide — studied for calming without sedation, and without the dependence profile of benzodiazepines.
Semaglutide
The peptide that changed the conversation — the original blockbuster GLP-1 agonist, with the deepest human trial record of any compound on this site.
Semax
Selank's energizing sibling — a Russian-developed cognitive peptide studied for focus, memory, and BDNF elevation.
Sermorelin
The clinic-standard growth-hormone peptide — the first 29 amino acids of natural GHRH, with decades of prescription history behind it.
TB-500
BPC-157's usual partner — studied for flexibility, tissue repair, and reducing inflammation across the whole body rather than one site.
Tesamorelin
The most clinically proven GHRH analog — an FDA-approved drug (for HIV-related belly fat) that research circles study for visceral fat specifically.
Thymosin Alpha-1
The immune-modulation peptide — an approved drug in 30+ countries that trains the immune system's response rather than suppressing or overstimulating it.
Tirzepatide
The proven dual GLP-1/GIP agonist — an approved medication class with ~20% trial weight loss, studied in research form for metabolic health.
