We report net peptide content, not just purity — so the milligrams you dose aren't padded with water and counter-ion. RP-HPLC purity and ESI-MS identity, on a lot-numbered COA.
Net peptide content, not just purity — RP-HPLC + ESI-MS, lot-numbered COA.

Melanotan-1, Melanotan-2, ACE-031, Adipotide-FTTP, EPO. Peptide and protein research reagents that operate outside the GH / cognitive / hormonal / immune / mitochondrial / repair / longevity / Khavinson clusters.
Who sources this class & for what
Other research peptides in this category — Melanotan-1, Melanotan-2, PT-141, ACE-031, Adipotide-FTTP, EPO, HCG, HMG — ship to research labs studying topics outside the GH / cognitive / immune / mitochondrial / repair / longevity / Khavinson clusters. Each peptide has its own analytical-packet emphasis (e.g. glycoprotein bioassay in IU/mg for HCG; cyclised-form confirmation for oxytocin) noted in the per-product CoA scope.
