What Is SEMAX

Mechanism & research

<!-- form-tracked-clarification --> Peptigrity tracks plain Semax (the heptapeptide MEHFPGP). N-Acetyl Semax Amidate is a chemically distinct, longer-acting modified analog sold separately by some vendors — it will get its own page once we add it to our test database. <!-- /form-tracked-clarification -->
