GHK-Cu + BPC-157 — Skin & Repair
ghk-cu remodels the skin's collagen matrix while bpc-157 drives repair and new blood supply — remodel plus repair, two complementary levers for skin and connective tissue.
Why this protocol
ghk-cu, the copper tripeptide, stimulates collagen and elastin and helps rebuild the skin's support matrix. bpc-157 is studied for wound healing and for bringing fresh blood supply (angiogenesis) to repairing tissue.
Together they cover two stages: GHK-Cu remodels the matrix while BPC-157 heals and vascularizes it. Different levers — rebuild and repair — rather than two takes on the same one, which is what makes the pairing additive.

Cycle & schedule
Cycle (8–12 weeks)
Co-inject GHK-Cu 1 mg + BPC-157 250–500 mcg once daily, rotating sites across the week.
Washout (4 weeks)
A 4-week break before reassessing skin and tissue quality and deciding whether to repeat.
