Melanotan I lab report: purity and COA

What to look for on a Melanotan I COA

• A lot number that matches the vial in your hand, and a test date after that lot was made.
• HPLC purity of 98% or higher, with mass-spec identity confirming it is Melanotan I.
• A named lab, ideally ISO 17025 accredited, and endotoxin and sterility results for anything that will be injected.
• A measured amount close to the label. Large gaps are a red flag.

Purity is HPLC area percent as reported by the lab; some reports confirm content and identity without a purity figure. Reports are the supplier’s published PDFs; we don’t test vials ourselves. See our methodology and affiliate disclosure.
