This is the honest version of the question everybody actually types. “I’m losing my hair, what peptide?” gets you the compounds people push for it, each one carrying the grade of evidence that exists in humans. Sometimes that grade is excellent. Usually it isn’t.
A compound appearing under a condition means somebody claims it helps — a paper, a clinic, a vendor, a forum. It is not a recommendation and it is not a finding that it works. The grade beside it is the part that matters. Where an approved treatment exists for your condition, the entry says so, because a peptide with animal-only data is not an alternative to a treatment with trials behind it.
Every claim attached to any compound on the site. The number beside each is how many compounds carry that claim.
