recoverypeptidestissue-repair

BPC-157 & TB-500 are the two most researched recovery peptides, with complementary mechanisms. BPC-157 (Body Protection Compound) accelerates tendon, ligament, & gut repair via angiogenesis & growth factor upregulation. TB-500 (Thymosin Beta-4) promotes systemic tissue repair, reduces inflammation, & improves mobility. GHK-Cu supports collagen synthesis & skin regeneration. Note: all three are research compounds not approved for human therapeutic use.
