Misconception: Topical GHK-Cu is as effective as injectable transdermal penetration of peptides is limited by molecular size (GHK-Cu = 340.84 Da, near the upper limit for passive diffusion)
Carol Ferguson I had a headache for 4 years, about 75 % of the time
Purity verification for a laboratory grade peptide like GHK-Cu should rely on supplier-provided Certificates of Analysis that include HPLC chromatograms, purity percentage (typically expressed as 98% for research-grade material), and mass spectrometry data confirming molecular identity
The answer is nuanced, focusing on how these two antioxidants "spare" and support each other at the cellular level
Anti oxidants are compounds that work against ( anti -) that damage, basically protecting our cells from the oxidative damage caused by free radicals
