Evidence & research
Animal model
A non-human species used to study a disease or intervention before human testing.
In plain terms
Much of the enthusiasm around healing and longevity peptides rests on rodent studies. Rodents are not small humans: they differ in metabolism, lifespan, and — for the injury models used in tendon-healing research — in how the tissue heals.

BPC-157 is one of the most confidently discussed peptides on the internet. PubMed indexes no completed randomized controlled trial of it in humans. Here is what does exist, and what it can support.
TB-500 is a fragment of thymosin beta-4, and the human trials people cite for it were run on the full-length protein. Here is what each has actually been shown to do.
