If you had to pick one: GHK-Cu has broader biological reach (roughly 4,000 genes modulated versus 300-500 for retinol) [3] and a higher responder rate for collagen improvement in the only direct comparison
While HPLC tells you how pure the sample is, mass spectrometry tells you whether the main component is actually BPC-157
