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 injection calculator helps with reconstitution, and the FAQ answers common questions.
Free registered users also get the Injection 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
GLP-1 receptor agonist and approved gold standard of the first generation of weight-loss injections - FDA-approved for obesity, type 2 diabetes, cardiovascular risk reduction (March 2024) and MASH with liver fibrosis (August 2025); brand names Ozempic and Wegovy.
DetailsDual GLP-1/GIP agonist ("twincretin") - in SURMOUNT-5 (NEJM 2025) achieved 20.2 % vs. 13.7 % weight loss versus semaglutide (Wegovy), officially approved.
DetailsTriple agonist (GLP-1/GIP/glucagon) - Phase 3 (TRIUMPH-4) confirmed up to 28.7 % weight loss at 68 weeks; NDA filing expected Q4 2026.
DetailsMitochondrial peptide ("exercise in a bottle") - activates AMPK, optimises cellular energy. Experimental.
DetailsSS-31 (Elamipretide) has been FDA-approved since September 2025 as FORZINITY - the first mitochondria-targeted drug ever. It binds cardiolipin, stabilises the cristae and improves mitochondrial function in Barth syndrome.
DetailsRegenerative peptide derived from gastric juice - promotes angiogenesis and healing. Three small, uncontrolled human pilot studies (2021-2025) without placebo; an active Phase 2 trial is underway. WADA-prohibited.
DetailsCopper-complex tripeptide (glycyl-L-histidyl-L-lysine) and the gold standard of regenerative skincare - drives collagen, elastin and wound healing. Very well researched.
DetailsGrowth-hormone secretagogues: they stimulate the body's own HGH release in natural pulses instead of suppressing it.
DetailsNeuro-peptides from Moscow: Selank against anxiety (without drowsiness), Semax as a nootropic (BDNF up). Approved in Russia.
DetailsPre-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.
DetailsCompounding blend of four well-known peptides (GHK-Cu, BPC-157, TB-500, KPV) in an 80 mg vial; targets tissue repair, regeneration and systemic anti-inflammation. No standalone human trials of the blend.
