research market · not for human use
A lit region shows where studies measured an effect, not that a compound works there. Most research-market compounds are not FDA-approved.
Evidence grades come from the published literature; no vendor can pay for a grade or a ranking. Some outbound links are affiliate links; they never affect grades, scores or order.

short answers
atlas questions
What is the evidence atlas?
A map of where peptides have been studied in the body and how strong that research is. Each compound has one grade from A (approved, strong human outcome data) to F (contradicted, unsafe, or identity problems), plus the highest rung of evidence it reached.
What is the evidence ladder?
Six rungs: cell studies, animal studies, small human studies, a phase 2 trial, a phase 3 trial, approval somewhere in the world. The ladder shows how far research got; the grade says what it found. AOD-9604 reached phase 2b and still grades F because the trial failed.
What does a glowing region mean?
That published studies measured an effect there. Mint means it was measured in people; periwinkle means animals or cells only. A lit region is not a claim that a compound works there.
Can a vendor pay for a better grade or ranking?
No. Evidence grades come from the published literature and vendor grades from lab data. Some outbound links are affiliate links; they never affect grades, scores or order.
Is this medical advice?
No. PeptideTech is an independent information service. Research-market compounds are sold as research chemicals and most are not approved for use in people.
