Don't start with popularity. Start with what we actually know. Compare human evidence, community attention, regulatory status and the distance between the story people tell and the evidence that exists.
Every profile uses the same editorial framework so radically different compounds can be evaluated on the same page without pretending the evidence is equivalent.
Our fully researched, source-backed deep dives. Compare Human Evidence, Community Signal, The Gap, outcome and regulatory status using one consistent editorial framework.
Recovery's most talked-about peptide—and one of its biggest evidence gaps.
A triple-agonist obesity medicine with unusually strong clinical weight-loss data.
Real approval and strong human evidence—with an indication narrower than its biohacking reputation.
An endogenous mitochondrial signal whose biology is more established than its therapeutic use.
A tiny anti-inflammatory peptide with a broad preclinical story and almost no human therapeutic evidence.
A mitochondria-targeting peptide that became an FDA-approved medicine for Barth syndrome.
A recovery-culture staple whose reputation frequently borrows evidence from full-length thymosin beta-4.
51 peptides tracked. The seven flagship profiles above are our deepest evidence reviews. The additional 44 entries remain available while we progressively upgrade them into full Evidence Profiles.
A five-dot Human Evidence score does not mean “better peptide.” It means the compound has a deeper human evidence base for at least one defined use.
Recovery culture has built a remarkably confident story around a compound with only tiny, uncontrolled human datasets.
Powerful late-stage clinical evidence is colliding with an unapproved online market. Trial efficacy and product legitimacy are separate questions.
Related molecules cannot simply inherit one another's clinical evidence. TB-500 and full-length thymosin beta-4 make that distinction unusually clear.
One of the rare peptide stories to cross from experimental research into an FDA-approved medicine—while retaining a much broader biohacking reputation.
The Peptide Index is one way into the science. Outcome Hubs reverse the lens: begin with recovery, metabolic health, cognition, gut health or longevity, then ask which interventions actually have evidence.
