The Index

How the Index works

The same process.

We follow an identical methodology for every compound — from primary literature through to evidence grading and the editorial wall. The process doesn't change based on what's in stock.

01

Primary literature review

PubMed search. Every paper, not just abstracts. Cherry-picking flagged and excluded.

How we grade

The evidence scale, explained

Every compound is graded by the highest quality human study completed to date. We never upgrade based on what's in the catalogue — if the science isn't there, we say so.

Pre-clinical

In-vitro & animal only

Mechanism studied in lab settings. No human trial data published.

e.g. BPC-157, Epitalon, GHK-Cu
Phase I / II

Early human trial data

Early human safety data may be available. Efficacy remains uncertain.

e.g. Semax, PT-141, CJC-1295
Phase II / III

Controlled trial evidence

Controlled human trial data may be available. Check endpoints, comparators, and trial status.

e.g. Retatrutide, Tesamorelin
Clinical / Approved

Licensed in one+ jurisdictions

Regulatory approval for at least one indication or jurisdiction; context matters.

e.g. Semaglutide (pharma form)

PEPTIDE

Peptide

A short chain of amino acids studied for specific receptor and enzyme interactions.

RUO

Research Use Only
