Recruiting trials, by compound
Registrations for the peptides and supplements we cover that are recruiting or about to start, in plain words, straight from ClinicalTrials.gov. Filter each compound's list by status, phase and US state, then read the listing itself.
Trial Finder Read from ClinicalTrials.gov Oct 20, 2026 1,962 registrations, 670 with US sites How it works
We never say who qualifies. Each listing names its own criteria, and only its study team can say whether someone can join. This page shows what the registry says; it is not medical advice.

How the Trial Finder works
Where the listings come from. On Oct 20, 2026 we asked the ClinicalTrials.gov API (version 2) for registrations with the status recruiting or not yet recruiting that list each of our 696 compounds as an intervention, searching the page name and the aliases that name the compound itself. The snapshot is stored with its date and refreshed by hand; a registration can change status after that date, so the listing is the record.
What counts as a match.The registry search also matches synonyms and condition text, so we keep a registration only when one of its study arms names the compound. On a supplement, that arm has to be a supplement or a product named for it, and not one given by injection, infusion or inhalation, on the skin or as a sulfate salt: magnesium sulfate in obstetrics is a drug use, not the magnesium page's subject. We keep up to 40 per compound, recruiting first, then the most US sites.
What we write and what we quote.Titles, criteria, conditions, study arms, summaries and contacts are quoted as registered. The “In plain words” line is built from the listing's own fields (phase, ages, sponsor, enrollment, sites) by a fixed template, never by a model. “Read closely” marks a registration where an editor found registry facts worth checking before contacting the study team, and says what they are.
What we never do. Assess eligibility, rank trials, or suggest joining one. Ask the study team listed on each registration, and your own clinician.
