N-Acetyl Semax Amidate


Molecular Formula:C37H51N9O10S

CAS: 80714-61-0

Sequence: MEHFPGP

N-Acetyl Semax Amidate is the newest analog of Semax. It crosses the blood brain barrier easier than the original form of Semax and therefore is more potent by weight.  Upon receipt, use included medicine syringe to remove solution from the spray bottle and transfer into the amber container containing peptide, shake gently and let dissolve. This should take around 30 seconds. Then transfer back into the spray bottle and immediately refrigerate. Product should remain in refrigerator when not in use.


N-Acetyl Semax Amidate, Verified by HPLC to exceed 99.30% purity.

L-Methionyl-L-α-glutamylhistidyl-L-phenylalanyl-L-prolylglycyl-L-proline, (Pro8,Gly9,Pro10)ACTH-(4-10)

Status of N-Acetyl Semax Amidate nasal spray

N-acetyl Semax spray is a medication in Russia and Eastern Europe for stroke and other types of brain injury.  In the US, it is an unregulated substance.
