Common questions
Can Semax and Selank be resolved chromatographically in a blend?
Yes — they differ in sequence and hydrophobicity sufficiently to separate under standard RP-HPLC conditions, allowing individual quantification.
Where can I see the Semax / Selank certificate of analysis?
Every published Semax / Selank lot has its own certificate page on this site, listed under "Semax / Selank COA" above. There are 2 published lots; the most recent, lot SLSM1515N0526, was reported on 2026-05-27 at 99.4% purity by HPLC-UV. The certificates are issued by AxisPharm, LLC, an independent laboratory.
