N-Acetyl Semax Amidate — commonly abbreviated NASA — is a structurally modified analog of Semax, itself a synthetic ACTH(4-10) fragment analog. Two modifications distinguish it: N-terminal acetylation and C-terminal amidation. Both are standard medicinal-chemistry strategies for altering a peptide's stability profile, which is why NASA is studied separately from unmodified Semax rather than as a drop-in equivalent.
This 30mg presentation is the extended research size. Durham Peptides also stocks standard Semax 10mg for researchers running comparative work between the modified and unmodified forms.
BENEFITS
Modified structure — N-terminal acetylation plus C-terminal amidation vs base Semax
Extended research size — 30mg suits multi-arm or longer-running study designs
Comparative work — pairs directly against standard Semax, also stocked
Cognitive research lineage — descends from the well-documented ACTH(4-10) analog family
Verified identity — MS-confirmed against a Janoshik report you can check independently

WHAT IS N-ACETYL SEMAX AMIDATE?
N-Acetyl Semax Amidate (NASA) is a structurally modified analog of Semax, which is itself a synthetic analog of the ACTH(4-10) fragment. NASA carries two modifications relative to base Semax: acetylation at the N-terminus and amidation at the C-terminus.
N-ACETYL SEMAX AMIDATE VS SEMAX — WHAT'S THE DIFFERENCE?
They are different compounds. Semax is the unmodified ACTH(4-10) analog. N-Acetyl Semax Amidate adds N-terminal acetylation and C-terminal amidation — modifications studied for their effect on the molecule's stability profile. Because of that, researchers treat them as separate compounds and often run them in parallel arms rather than substituting one for the other. Durham Peptides stocks both.
WHY THE 30MG SIZE?
30mg is the extended research size, suited to multi-arm or longer-running study designs where a 10mg vial would require repeat sourcing mid-study. Researchers running pilot work may prefer the standard Semax 10mg vial.
HOW SHOULD IT BE STORED AND RECONSTITUTED?
Store the lyophilized vial at 2–8°C, protected from light and moisture. Reconstitute with bacteriostatic water (sold separately) for research handling. Once reconstituted, keep refrigerated and use within an appropriate research timeframe.
HOW IS IT SHIPPED IN CANADA?
Orders placed and paid before 5:00 PM EST ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.
IS THE COA VERIFIABLE?
Yes. Every batch is Janoshik-tested with a unique report key you can confirm independently — see our guide on how to verify a Janoshik unique key.
