BPC-157
Strong in rats. Three tiny human studies, none with a comparison group.
Grade C: Animals and lab only
Looks good in rats or in a dish. Not proven in people.
The grade is for the use people talk about, not for every use. Filed under: Repair.
How it works
Thought to help new blood vessels grow into injured tissue. Shown in animals, not confirmed in people.
How it was given in studies
Three tiny studies used three different routes: into the knee joint, into the bladder, and into a vein.
30 people in total across all three.
This is what the studies did. It is not a how-to. Source: 2026 review of the human studies. Acta Orthopaedica Belgica.
What studies saw
Rat tendons healed faster within weeks. In one 12-person knee study, 7 reported pain relief lasting over six months.
The trade-off
Human safety has barely been tested. What is in the vial is unverified.
When it showed up, in studies
Rat tendons healed faster within weeks. No human timeline.
