N-Acetyl Semax Amidate Nasal Spray — 30mg
Research-grade N-Acetyl Semax Amidate in a metered nasal atomiser format — 30mg lyophilized peptide supplied with sterile diluent for researcher reconstitution. N-Acetyl Semax Amidate is a structurally modified analog of Semax, carrying N-terminal acetylation and C-terminal amidation. 99%+ purity verified by an independent third-party lab via HPLC and mass spectrometry.
Ships unmixed — reconstitute on arrival for full-strength material.
For laboratory research use only.
Not for human or veterinary use.
Not intended for diagnosis, treatment, cure, or prevention of any disease.
Use only in controlled laboratory settings by qualified personnel following appropriate safety procedures.
N-Acetyl Semax Amidate 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 standard strategies for altering a peptide's stability profile. This nasal atomiser format supplies the same research-grade N-Acetyl Semax Amidate stocked in vial form, packaged for intranasal research handling.
SHIPPED UNMIXED — AND WHY THAT MATTERS
Durham Peptides does not ship pre-diluted nasal sprays. Peptides in solution are materially less stable than in lyophilized form, so a bottle that is mixed at the warehouse begins losing potency the day it is filled and continues to do so in transit and in storage. Instead, the lyophilized peptide and the diluent travel separately and the researcher reconstitutes on arrival — which means full-strength material and a known, controlled in-use window rather than an unknown one.
Every nasal spray ships with sterile water preserved with 0.3% potassium sorbate, supplied specifically for this format. No separate bacteriostatic water purchase is required.
BENEFITS
Ships unmixed — full-strength lyophilized material, not a solution degrading in transit
Diluent included — sterile water with 0.3% potassium sorbate, no separate purchase needed
Metered atomiser — consistent, repeatable delivery volume per actuation
Doubly modified analog — N-terminal acetylation and C-terminal amidation on the Semax scaffold
Verified identity — MS-confirmed against a third-party lab report you can check independently

DOES THE NASAL SPRAY COME PRE-MIXED?
No, and that is deliberate. Peptides are materially less stable in solution than in lyophilized form, so a pre-diluted bottle starts losing potency the day it is filled. Durham Peptides ships the lyophilized peptide and the sterile diluent separately so the researcher reconstitutes on arrival — full-strength material, and a known in-use window rather than an unknown one.
DO I NEED TO BUY BACTERIOSTATIC WATER SEPARATELY?
No. Every nasal spray ships with its own diluent — sterile water preserved with 0.3% potassium sorbate, supplied specifically for the atomiser format. This differs from the lyophilized vials in our catalogue, which are reconstituted with bacteriostatic water sold separately.
WHAT IS N-ACETYL SEMAX AMIDATE?
N-Acetyl Semax Amidate is a structurally modified analog of Semax, itself a synthetic analog of the ACTH(4-10) fragment. Two modifications distinguish it — N-terminal acetylation and C-terminal amidation — both standard strategies for altering a peptide's stability profile.
HOW DOES THIS DIFFER FROM PLAIN SEMAX NASAL SPRAY?
They are separate compounds, and Durham Peptides stocks both. Semax is the ACTH(4-10) analog itself; N-Acetyl Semax Amidate carries two additional structural modifications on that scaffold — acetylation at the N-terminus and amidation at the C-terminus. Because the difference is structural rather than a difference in loading, researchers commonly run the two in parallel arms to compare the modified and unmodified forms directly.
NASAL SPRAY VS VIAL — WHICH SHOULD I CHOOSE?
Both supply the same research-grade N-Acetyl Semax Amidate. The vial — N-Acetyl Semax Amidate — 30mg — is the flexible option, since the researcher chooses the reconstitution volume and therefore the working concentration. The nasal atomiser is the convenience option, arriving with matched diluent and a metered actuator for consistent delivery volume. The choice depends on whether the protocol calls for a custom concentration or a repeatable fixed one.
HOW SHOULD IT BE STORED AFTER RECONSTITUTION?
Keep the bottle refrigerated at 2–8°C and protected from light both before and after reconstitution. Once reconstituted, use within an appropriate research timeframe — a peptide in solution has a materially shorter usable life than the sealed lyophilized material.
HOW IS IT SHIPPED IN CANADA?
Orders placed and paid before 4:00 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 independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.
