BPC-157 is believed to work through several overlapping mechanisms
That said, within the community of people that use BPC-157 for therapeutic reasons for tissue rejuvenation and repair, there's been an ongoing debate as to whether or not you can take it systemically
Route of administration changes the result: supervised subcutaneous injection of 503A compounded GHK-Cu produces systemic and targeted effects that topical serums cannot replicate
What GHK-Cu adds to the formulation: Gene expression modulation across hundreds of genes including collagen genes (Type I, III), tissue inhibitors of metalloproteinases, anti-inflammatory mediators Collagen synthesis stimulation, specifically Type I and Type III collagen the structural proteins of skin, connective tissue, and many other tissues Anti-inflammatory signaling through investigated effects on TNF-, IL-6, and NF-B pathways Copper-peptide chemistry effects including cofactor activity for skin-relevant enzymes Skin-research and hair-research applications (the GHK-Cu literature in these areas is substantial) For the GHK-Cu deep-dive, see Copper Peptides Explained
BPC-157 was my Hail Mary before getting surgery. What he tells athletes now McKnight said the experience has changed how he thinks about what athletes are told by medical providers, coaches and wellness clinics
Copper peptides have shown benefits for both fine lines and deep wrinkles, particularly in sun-exposed areas
