Peptigrity tracks N-Acetyl Semax Amidate across 219 shops with 8 independent lab tests and an average HPLC purity of 99.82%.
N-Acetyl Semax Amidate is a chemically distinct, longer-acting derivative of Semax. The molecule carries an N-terminal acetyl group and a C-terminal amide on the parent heptapeptide MEHFPGP, modifications that slow enzymatic degradation and extend duration of action relative to plain Semax. Molecular formula C39H53N9O11S; molecular weight 855.97 Da; CAS 1366000-95-2. Some vendors sell this compound under SKU codes such as CB813771902 alongside their plain-Semax product line — the two should not be conflated. Peptigrity tracks N-Acetyl Semax Amidate as its own compound when reviewed shops list it as a distinct SKU and lab tests verify the modified structure.
