The library

Peptide Library

Every profile covers what the compound is, what researchers use it for, commonly reported protocols, reconstitution, storage, and cautions.

Weight & Metabolic

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.

Weight & Metabolic

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.

Recovery & Repair

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.

Weight & Metabolic

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.

Growth Hormone Axis

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.

Sleep & Recovery

DSIP

The sleep peptide — studied since the 1970s for deepening slow-wave sleep, which is where every other kind of recovery actually happens.

Energy & Longevity

Epithalon

The telomere peptide — a four-amino-acid compound from Russian longevity research, studied for telomerase activation and sleep-hormone normalization.

Skin & Longevity

GHK-Cu

A naturally occurring copper-binding peptide studied for skin quality, hair, wound healing, and tissue remodeling — the cosmetic-longevity workhorse.

Immune & Resilience

Glutathione

The body's own master antioxidant — a tripeptide on every IV-therapy and med-spa menu, studied for detoxification, recovery, and oxidative stress.

Advanced / Growth

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.

Growth Hormone Axis

Ipamorelin

The cleanest of the GH secretagogues — triggers a growth-hormone pulse without meaningfully raising hunger or cortisol. CJC-1295's standard partner.

Men's Health

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.

Gut & Inflammation

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.

Skin & Tanning

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.

Skin & Tanning

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.

Weight & Metabolic

MOTS-c

The "exercise in a vial" research peptide — encoded in mitochondrial DNA, studied for insulin sensitivity, endurance, and metabolic flexibility.

Energy & Longevity

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.

Men's Health

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.

Weight & Metabolic

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.

Mind & Mood

Selank

A Russian-developed anti-anxiety peptide — studied for calming without sedation, and without the dependence profile of benzodiazepines.

Weight & Metabolic

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.

Mind & Mood

Semax

Selank's energizing sibling — a Russian-developed cognitive peptide studied for focus, memory, and BDNF elevation.

Growth Hormone Axis

Sermorelin

The clinic-standard growth-hormone peptide — the first 29 amino acids of natural GHRH, with decades of prescription history behind it.

Recovery & Repair

TB-500

BPC-157's usual partner — studied for flexibility, tissue repair, and reducing inflammation across the whole body rather than one site.

Growth Hormone Axis

Tesamorelin

The most clinically proven GHRH analog — an FDA-approved drug (for HIV-related belly fat) that research circles study for visceral fat specifically.

Immune & Resilience

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.

Weight & Metabolic

Tirzepatide

The proven dual GLP-1/GIP agonist — an approved medication class with ~20% trial weight loss, studied in research form for metabolic health.
