Peptide safety & interactions: what data actually exists
Real safety information for a peptide comes from one of three places: a regulator's label (for approved — or withdrawn — drugs), the adverse events collected in human clinical trials, or nowhere at all. This page maps all 663 peptides in the encyclopedia by which of those they have, alongside whether any drug-interaction research exists and the overall evidence grade. It is an honest map of where safety data is and is not, not a safety rating and not medical advice.
The most important safety fact on this site: most peptides here are research-only, which means there is no human safety data for them at all — and “no drug interactions found” means the interaction has never been studied, not that it is safe to combine. Absence of reported harm is not evidence of safety. A withdrawn status is the opposite — a strong, documented safety signal. Grey Peptides sells nothing and links to no vendor.

How to read this map (and what it is not)
“Safety data” says where human safety information for a peptide comes from: Regulatory review (an approved or diagnostic product has an FDA or foreign label with warnings and contraindications), Clinical-trial data (an in-trials or discontinued compound collected adverse events in people), Withdrawn (a product pulled from market — a documented safety signal, read the entry), or No human safety data (research-only and preclinical compounds never tested in people). “Drug-interaction research” reflects whether any interaction study or label interaction exists for the peptide; None found means unstudied, never “safe to combine.” “Evidence grade” is our editorial reading of the overall evidence (see how we grade evidence). This is a map of data availability, not a safety score: each peptide's own page carries its reported effects, contraindications and interaction detail with sources. See also What Works, the Trials & Outcomes tracker, and the interaction matrix. Of 663 peptides, 273 have no human safety data and 503 have no drug-interaction research.
