N-Acetyl Semax + N-Acetyl Selank Nasal Spray — 60mg
Research-grade N-Acetyl Semax Amidate and N-Acetyl Selank Amidate in a metered nasal atomiser format — 60mg total lyophilized peptide supplied with sterile diluent for researcher reconstitution. Two nootropic research peptides from unrelated parent compounds, combined in one bottle. 99%+ purity verified by Janoshik Analytical 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.
This blend pairs the two most-studied nootropic research peptides in their modified amidate forms, combined in one atomiser. Semax derives from the ACTH(4-10) fragment and is studied in neuroprotection and cognitive models; Selank derives from tuftsin and is studied in anxiolytic and neuroimmune models. Different parents, different pathways, commonly run together. This nasal atomiser format supplies the same research-grade material 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
Two distinct parent compounds — Semax and Selank cover separate pathways in a single reconstitution
Verified identity — MS-confirmed against a Janoshik report you can check independently
WHAT RESEARCHERS LOOK AT
Neuroprotective and cognitive endpoints attributed to the Semax component
Anxiolytic and neuroimmune signalling attributed to the Selank component
Whether unrelated parent structures produce additive rather than overlapping effects
Intranasal versus parenteral delivery in comparative research models
Post-reconstitution stability across the in-use window

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.
IS THERE A VIAL VERSION OF THIS BLEND?
This blend is offered as a nasal atomiser only — there is no combined vial version. Researchers who want vial format, or who need the two compounds in different proportions, should buy N-Acetyl Semax Amidate — 30mg and N-Acetyl Selank Amidate — 30mg separately; both are stocked. The atomiser is the option when a fixed, pre-combined ratio and a metered delivery volume are what the protocol calls for.
WHAT IS N-ACETYL SEMAX + N-ACETYL SELANK?
Two separate research peptides in one bottle, both supplied in their modified amidate forms. Semax derives from the ACTH(4-10) fragment and is studied in neuroprotection and cognitive models; Selank derives from tuftsin and is studied in anxiolytic and neuroimmune models. Both carry N-terminal acetylation and C-terminal amidation.
WHY COMBINE SEMAX AND SELANK?
Because they descend from unrelated parent peptides and are studied for different pathways, the pairing covers both in a single reconstitution rather than duplicating one mechanism. Semax comes from the ACTH(4-10) fragment and Selank from tuftsin, so the two are not variations on the same structure.
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 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.
