Adamax vs Semax
Adamax is Semax with two changes: an acetyl group on the N-terminus and an Ala-Gly extension after the Semax sequence, taking it from 7 to 9 residues.
That raises the molecular weight from 813.93 g/mol for Semax to 984.10 g/mol for Adamax.

Questions
What is the structural difference between Adamax and Semax?
Adamax is Semax with two changes: an acetyl group on the N-terminus and an Ala-Gly extension after the Semax sequence, taking it from 7 to 9 residues. That raises the molecular weight from 813.93 g/mol for Semax to 984.10 g/mol for Adamax.
How are Adamax and Semax stored as sealed powder?
Adamax: Store refrigerated or at −20 °C, protected from light; use desiccant as needed. Semax: -20°C, protected from light and moisture; stable long term.
How is the identity of Adamax and Semax confirmed?
By mass spectrometry: the measured mass is compared with the expected molecular weight, 984.10 g/mol for Adamax and 813.93 g/mol for Semax. Purity is measured separately by HPLC, and every lot we sell has its certificate at luvaminos.com/coa.
