FDA Update

Jul 2026

Avail. Notes

Not FDA-approved for any human use; sold as a research chemical; WADA prohibited (S0). Placed on the interim FDA 503A "Category 2" list (significant safety risks) in September 2023. In February 2026 HHS announced an intention to move several peptides toward "Category 1," but the FDA did not reclassify BPC-157. In April 2026 the FDA removed BPC-157 from the Category 2 list because the nomination was withdrawn — this does not authorize compounding, and BPC-157 is not on the 503A bulks list. Provider pricing varies by concentration, formulation, and source; use the PeptideBase directory to compare active providers and current availability.

Not FDA-approved; WADA prohibited (S2). Placed on the interim FDA 503A "Category 2" list (significant safety risks) in September 2023, alongside BPC-157. The FDA did not reclassify it to "Category 1" in February 2026 (that was an HHS announcement of intent, not an FDA action). In April 2026 the FDA removed the thymosin β4 fragment (TB-500) from Category 2 because the nomination was withdrawn — this does not authorize compounding.

About BPC-157

BPC-157 is believed to accelerate angiogenesis and upregulate growth hormone receptors locally at injury sites. It appears to promote fibroblast migration and collagen synthesis, contributing to faster tissue remodelling. Animal studies suggest systemic effects via modulation of the dopaminergic and serotonergic systems, though human data remain limited.

Research Areas

tissue repair across tendon, muscle, nerve, and gut — most broadly studied recovery peptideanti-inflammatory via COX-2 and NF-κB pathway modulationangiogenesis and wound healing via VEGF and nitric oxide system upregulationoral or subcutaneous administration studied — systemic and local tissue effects documented

About TB-500

TB-500 exerts its effects primarily through promotion of actin polymerisation and cell migration. It upregulates the expression of beta-4 thymosin, which facilitates endothelial and muscle satellite cell movement to injury sites. Unlike BPC-157, TB-500 appears to act via a more systemic mechanism rather than locally at the administration site.

Research Areas

actin binding and cellular migration facilitation — core mechanism driving tissue repairwound healing and anti-inflammatory effects across muscle, tendon, and cardiac tissuethymosin beta-4 C-terminal fragment — angiogenesis and systemic distributionsubcutaneous injection — frequently combined with BPC-157 in recovery research stacks
