ghk cu peptide structure GHK‑Cu Copper Research Solution GHK-Cu may Prevent Oxidative Stress

Its a small chain of amino acids (the building blocks of protein) that was originally identified in human stomach (gastric) juice

In September 2023, the FDA added injectable GHK-Cu to a list of compounded substances considered high-risk due to limited safety data

It may be used off-label by qualified medical providers as an investigational therapy, and availability through compounding pharmacies is subject to evolving regulatory guidance

You can stack AHK-Cu with other peptides like GHK-Cu, BPC-157, TB-500, and growth hormone secretagogues, but timing separation of 4590 minutes prevents copper ion saturation and maximizes bioavailability of both compounds
