What the market shows
PeptidePrices found 11 in-stock listings from 11 vendors, checked through Oct 8, 2026. The lowest 10mg cost is 40% below the vendor median of $46.74; 5 vendors (45%) fall below that median. 10 of 11 vendors (91%) publish public COA evidence.
A public COA link shows that a vendor publishes testing data. It does not prove that every listed vial has a matching current report. Match the product, strength, batch, and lot before relying on a report.
How this report is calculated
The headline and median use each vendor's lowest whole-package checkout cost to obtain at least 10mg. Smaller packages are multiplied until the target is met, while larger packages retain their full checkout price. The lowest package total is shown only as secondary context because package sizes differ. Known public coupon discounts are applied. Shipping, tax, and unverified promotions are excluded.
Research context
What is N-Acetyl Selank Amidate? Research, safety, and status
Tuftsin is a four-residue fragment of the heavy chain of human immunoglobulin G, Thr-Lys-Pro-Arg, studied for decades for immune effects. Selank is tuftsin with Pro-Gly-Pro added at the C-terminus. A 2016 paper from the developers' institute says the tail was added "to improve its metabolic stability" and give a longer duration of action.
N-Acetyl Selank Amidate keeps those seven residues and changes both ends. The N-terminal threonine gets an acetyl group, so it no longer has a free amine. The C-terminal proline becomes an amide, so it no longer carries a free carboxylic acid. No residues are added or swapped.
Key research takeaways
Selank was already built for stability. Its developers added Pro-Gly-Pro to the end of tuftsin to make it last longer. Unlike Semax, there is no Selank-specific paper we could find testing whether capping the ends helps further.
Selank's breakdown does not run only from the N-terminus. In rat plasma the main products were Thr-Lys-Pro-Arg-Pro, Thr-Lys-Pro, Arg-Pro and Gly-Pro. That mix points to cuts inside the chain and at the C-terminal end as well.
Parts of Selank's activity have been tied to its fragment Gly-Pro. Capping both ends changes which fragments can form. Whether that helps, hurts or does nothing is unmeasured.
N-Acetyl Selank Amidate at a glance
PeptidePrices safety rating
5/10 · Not FDA-approved
Mechanism
Modified form of Selank (a tuftsin analog) with an acetylated N-terminus and amidated C-terminus, presumed to resist enzymatic breakdown. Its pharmacology has not been characterised separately from Selank.
Research areas
Anxiolytic and neuropeptide-analog research. Human clinical benefit of this modified form is not established, and Selank's Russian registration does not apply to it.
Regulatory / research status
Research / preclinical only
Half-life
Not established in direct human pharmacokinetic studies.
Storage
Lyophilized vial: store at -20°C long-term or 2-8°C short-term, protected from light.
Reported side effects
No published human safety data exist for the N-acetyl amidate form. Effects of the parent peptide Selank cannot be assumed to carry over, and research-market purity and identity vary.
Modified Selank analog with no human data; Selank's Russian approval does not transfer. Safety ratings summarize published clinical data, adverse-event reporting, and regulatory status. How PeptidePrices rates evidence. Research information only, not medical advice.
