MOTS-C mitochondrial function, metabolic regulation, cellular energy

Published in-vitro work commonly uses GHK-Cu in the range of 10 nM to 10 M, with 1 M as a frequently reported working concentration

Researchers using GHK-Cu in populations with impaired renal function should consider reducing dose frequency to every 72 hours instead of every 48 hours to avoid accumulation of copper, which is also renally excreted and can contribute to oxidative stress at excessive levels
