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.

CJC-1295, Sermorelin, Ipamorelin, GHRP-2/6, IGF-1 LR3, MGF, Tesamorelin and HGH-fragment 176-191. GHRH-receptor agonists, GHSR (ghrelin-receptor) agonists, and IGF-axis reagents for somatotropic-pathway research.
Who sources this class & for what
GH-axis peptides ship to research labs studying somatotropic-pathway pharmacology, IGF-axis signalling, and pulse vs. sustained-elevation GH biology. Buyers qualifying a new source typically request sequence verification on the first lot, the counter-ion form (acetate by default), and stability data at −20 °C. Blends — the CJC-1295 + Ipamorelin co-formulated lot is the canonical example — are co-lyophilised rather than solution-mixed so the ratio is locked at the lyophilisation step.
