What to Look for When Buying Melanotan II

The research peptide market is largely unregulated. Quality varies significantly between vendors. Here are the non-negotiable criteria for sourcing research-grade Melanotan II:

Third-party COA from an accredited US lab (HPLC + mass spectrometry)
Purity 98% or higher confirmed by HPLC analysis
Correct molecular weight verified by mass spectrometry
Lyophilized powder in sealed, labeled vials
US-based manufacturer with verifiable address
Transparent return and quality guarantee policy

COA Note: Melanotan II is a cyclic heptapeptide (MW approximately 1,024 Da). Verify HPLC purity 98% or higher and mass spec confirmation. Distinguish from Melanotan I (afamelanotide) — they have different structures and profiles.

Red Flags to Avoid

No certificate of analysis, or COA from an unaccredited lab
Price significantly below market rate (often indicates underdosing)
Vague sourcing with no lab details or country of origin
No customer service contact or physical address
Claims of FDA approval or human-use authorization
Suspiciously high purity claims without documentation
