The question is whether you can have both, and the answer is
Your body levels of GHK-Cu drop with age (from 200 ng/mL in youth to 80 ng/mL by age 60), so supplementing mimics youthful repair
Cells were lysed with 500 L of RIPA lysis buffer containing 150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, 0.1% SDS, 25 mM Tris-HCl, supplemented with protease and phosphatase inhibitors at a 1:100 dilution
BPC-157 and TB-500 are the two peptides most often studied together, so a pre-blended vial is a convenient, lower-cost way to study the pair at 99% HPLC purity, lyophilized and tested in Canada, with a COA per batch
A separate investigation compared the biological activity of the GHK-Cu peptide complex with helium-neon laser-based stimulation in similar preclinical wound models
