I found a product-specific COA PDF for GHK-Cu 50mg with batch GHK301 and an HPLC purity result of 99.771{d72cc670942bc50f878173a7ecfafa6ec3e4734f471515e76ac5c48244e11706}. The document shows content (58.18 mg) but no visible chromatogram, mass-spec, sterility/endotoxin, or contaminant panel. [Manually corrected: the pipeline batch-code check misread batch GHK301 as a 301 mg vial; the COA PDF itself (read directly) is titled GHK-Cu 50mg, batch GHK301, HPLC 99.771{d72cc670942bc50f878173a7ecfafa6ec3e4734f471515e76ac5c48244e11706}, content 58.18 mg.]
