Ac-SDKP vs BPC-157

Inhibits hematopoietic stem cell entry into S-phase. Blocks TGF-β1-mediated fibroblast activation, reducing collagen deposition. Promotes angiogenesis via VEGF upregulation. Regulated in vivo by ACE enzyme.

A naturally occurring tetrapeptide derived from thymosin beta-4 cleavage by prolyl oligopeptidase. Potent anti-fibrotic properties studied in cardiac, pulmonary, and renal fibrosis. Also promotes angiogenesis and wound healing.

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.

BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It is commonly researched for its role in soft tissue repair, particularly in tendons, ligaments, and muscle following injury or high training loads. Early research suggests it may also support gut integrity and systemic healing.
