Peptidepedia

80 compounds · every claim cited

Most of what you have read about peptides is selling you something.

This is the other kind of page. Every entry is graded on how much human evidence actually exists.

Each vial is one compound. How full it is, is how much human evidence exists for the use people take it for. Hover to name one.

All compounds

BPC-157

Preclinical

The most widely used healing peptide in the world, supported by a large rodent literature and zero completed randomised human trials.

Half-life~15 minutes (rat IV; no human PK published)

GHK-Cu

Preclinical

Copper-binding tripeptide with forty years of topical research behind it - and essentially none behind the injectable form people are buying.

Half-lifeMinutes in circulation; the copper complex itself persists in tissue longer

Retatrutide

Trials

Triple GLP-1 / GIP / glucagon agonist producing the largest weight loss recorded in any obesity trial to date. Investigational - not approved anywhere.

Half-life~6 days

Tirzepatide

Approved

Dual GIP / GLP-1 agonist and the most effective approved weight-loss drug currently on the market. Weekly injection with a real pharmacy supply chain.

Half-life~5 days

Tools

Reconstitution calculator

Vial size and bacteriostatic water into syringe units, with warnings when a dose is too small to measure accurately.

Side-by-side compare

Up to four compounds against each other on evidence, regulatory status, half-life, cadence and side effects.
