Healing & recovery peptides
The "Wolverine" category — huge claims, mostly animal data. Pep shows you exactly where the human evidence stops.
Rats heal, humans wait
BPC-157 and TB-500 have impressive rodent studies and almost no human efficacy data.
Watch the drug tests
TB-500 (TB-4) is on the WADA banned list — a real problem for tested athletes.
Promising ≠ proven
Mechanisms are plausible; that is not the same as it working in people.
Every Recovery peptide we've ruled on
See all categories →The recovery crowd's favorite peptide. Huge animal-study buzz, thin human data, and a lot of hype to sort through.
KPV (lysine-proline-valine) is the C-terminal tripeptide of the alpha-MSH hormone, commonly researched for anti-inflammatory activity in the gut and skin. It is not FDA-approved and is sold for laboratory research use only; effects and safety in people are still being studied and rest almost entirely on cell and animal work.
LL-37 is the only human cathelicidin antimicrobial peptide, a 37-amino-acid fragment your own immune cells release. It is commonly researched for antimicrobial activity, immune signaling, and wound healing. It is not FDA-approved and is sold for laboratory research use only; its effects in people are context-dependent and largely preclinical, and the same peptide has been linked to both healing and inflammatory conditions.
TB-500 is a synthetic fragment related to thymosin beta-4, commonly researched for tissue repair and recovery. It is not FDA-approved, its human evidence is thin, and it sits on the WADA prohibited list — a real problem for tested athletes.
Tesamorelin is a growth-hormone-releasing factor (GHRH) analog commonly researched for visceral abdominal fat and the growth-hormone/IGF-1 axis. The branded prescription version, Egrifta, is FDA-approved for one narrow use; research-grade tesamorelin sold for lab use is not that product and is not FDA-approved.
