Following a 10 min dark incubation period, the reaction was terminated by adding 100 L H 2 SO 4 to each well, and the Varioskan LUX microplatereader (Thermo Scientific) was utilized to measure the absorbance at OD 450

While researchers note that the LD50 (lethal dose) for GHK-Cu in murine models equates to an impossibly massive single dose of roughly 23,000mg for a 70kg human adultrendering acute lethal toxicity highly improbable at the standard aesthetic therapeutic doses of 5-50mgthe long-term cumulative effects of daily copper peptide injections remain entirely unmapped in human populations
