BPC-157
A pentadecapeptide derived from a sequence in human gastric juice. Most existing data is preclinical (animal models), exploring tissue repair, gut barrier, and tendon healing.
Full pageMultiple animal studies (rats, mice) show accelerated tendon, ligament, and gut-mucosa healing. Mechanism appears to involve angiogenesis and growth-factor expression.
Almost zero rigorous human RCTs. Anti-inflammatory and joint-recovery claims in humans are extrapolated from animal data and have not been independently replicated in well-controlled trials.
Human safety data is limited. Long-term effects are unknown. Regulatory status varies by region.
Reported anecdotally: localized irritation at injection sites, headaches. No robust clinical safety profile exists.
TB-500
Synthetic fragment related to thymosin beta-4. Investigated in animal studies for cellular migration and tissue remodeling.
Full pageAnimal studies suggest cellular migration and tissue remodeling effects, especially in cardiac and dermal wound models.
Human efficacy is essentially unproven. Safety profile in humans is undocumented in peer-reviewed RCTs.
Almost no human clinical data. Banned in competitive sport (WADA).
Limited human safety reporting; theoretical immunomodulation concerns.
