GHK-Cu + BPC-157 for skin and repair

GHK-Cu remodels the skin's collagen matrix while BPC-157 drives repair and new blood supply. Two complementary levers work together for skin and connective tissue.

8–12 weeks + 4-week washout

01

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. Rebuild and repair are different levers, not two takes on the same one, which is what makes the pairing additive.

Cycle & schedule

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