Peptides

A topic-sorted overview of common peptides - from metabolic and healing compounds to neuro-peptides. Each entry explains the mechanism, benefits and study status in plain terms and rates the evidence on a scale from 1 to 4.

Everything here is source-backed and purely informational - not medical advice and not a buying recommendation. The dosage calculator helps with reconstitution, and the FAQ answers common questions.

Free registered users also get the Dosage Manager: it stores the mixes and reconstitutions you create, calculates the doses from them, lets you log your injections and tracks along. You always keep the full picture!

Evidence scale: 1 = experimental · 4 = established/approved

Metabolism & Weight

Semaglutid

SM
Evidence 4/4

GLP-1 receptor agonist and the gold standard of the first generation of weight-loss injections - officially approved (Ozempic, Wegovy).

Details

Tirzepatid

TR
Evidence 4/4

Dual GLP-1/GIP agonist ("twincretin") - stronger weight loss than semaglutide, officially approved.

Details

Retatrutid

RT
Evidence 3/4

Triple agonist (GLP-1/GIP/glucagon) - up to 24.2 % weight loss in 48 weeks; currently in Phase 3 (TRIUMPH).

Mitochondria & Energy

MOTS-c

MS
Evidence 2/4

Mitochondrial peptide ("exercise in a bottle") - activates AMPK, optimises cellular energy. Experimental.

Details

SS-31

SS31 / ELAM
Evidence 3/4

Mitochondrial peptide that binds cardiolipin in the inner membrane, stabilises the cristae and restores ATP. Advanced human trials.

Details

Tissue Repair & Regeneration

BPC-157

BC
Evidence 2/4

Regenerative peptide derived from gastric juice - promotes angiogenesis and healing. Heavily hyped, few human trials; WADA-banned since 2022.

Details

GHK-Cu

GHK / GHK-Cu
Evidence 4/4

Copper-complex tripeptide (glycyl-L-histidyl-L-lysine) and the gold standard of regenerative skincare - drives collagen, elastin and wound healing. Very well researched.

Details

Growth Hormone & Anti-Aging

CJC-1295 / Ipamorelin

CJC / IPA
Evidence 2/4

Growth-hormone secretagogues: they stimulate the body's own HGH release in natural pulses instead of suppressing it.

Details

Neuro & Cognition

Selank & Semax

SK / XA
Evidence 3/4

Neuro-peptides from Moscow: Selank against anxiety (without drowsiness), Semax as a nootropic (BDNF up). Approved in Russia.

Details

Blends

Glow Stack

Blend GLOW / GLW
Evidence 3/4

Pre-made regeneration blend of GHK-Cu, TB-500 and BPC-157 in a 5:1:1 ratio - an all-in-one repair tool for skin, tendons and muscle.

Details

Klow Stack

Blend KLOW / KLW
Evidence 2/4

Proprietary longevity blend with a composition that is not publicly specified; targets cellular longevity, anti-apoptosis and neuronal protection. Experimental.
