N-Acetyl Selank Amidate

Selank, the Russian anti-anxiety nasal peptide, with two caps: an acetyl group on the front of the chain and an amide on the back. In shorthand it is Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH2. It is sold as a research chemical in vials and premixed sprays.

Sometimes. One seller sells this exact peptide as Adalank. Other sellers use Adalank for a hybrid of Adamax and Selank, a different molecule. Check the sequence on the label or certificate of analysis.

Guides report 2 to 3 times the potency, but no study has measured it, and nothing compares the two. Users disagree: some prefer it, one found plain N-acetyl Selank far better.

Guides range from 150 to 900 mcg a day, mostly as nasal sprays. One user who likes it nasally stays at 100 to 300 mcg; under the skin, 500 to 750 mcg once a day comes up. No label or trial dose exists.

One r/Peptides user runs that and likes it; the top reply calls it far too high. It sits well above the 100 to 900 mcg per dose that guides and most users describe, and high doses are where users report brain fog and memory trouble.

Users split. Several feel it more strongly by nasal spray and barely notice injections. Others felt nothing nasally and only responded to a subcutaneous dose.

Nobody has measured it. One user of an N-acetyl Selank spray (the thread does not say amidate) describes about 4 hours, and another describes about 12 hours of calm from a 750 mcg amidate injection. Guide half-life estimates range from 10 to 20 minutes to 4 to 6 hours.

Insomnia when taken late, brain fog at high doses, sedation, a spaced-out feeling, nasal drip from sprays and, for some, no effect at all. These are user reports; no study has looked.

Either, depending on how it hits you. Some users take it at bedtime and fall asleep fast; others get insomnia from any dose after 6 pm. Start in the morning until you know.

Powder in the freezer at -20 C, away from light. After mixing, keep it at 2 to 8 C. One premixed spray can sit at room temperature until opened, then goes in the fridge.

The back end. N-acetyl Selank keeps a free acid there; the amidate swaps it for an amide. They are different molecules with slightly different masses, though Reddit often uses "NA-Selank" for both.

It is a common pairing: the Semax version for focus, the Selank version for calm. Some users spray one in each nostril, and premixed blends of the two are sold.

One guide advises caution, because plain Selank acts on GABA and strengthened diazepam in rats. No interaction study exists for this variant.

It is not FDA approved and FDA does not name it. FDA has flagged plain Selank acetate for compounding risk. It is sold as a research chemical.
