Selank
Thr-Lys-Pro-Arg-Pro-Gly-Pro, a Tuftsin analog
Also sold as: Selanc · TP-7 · N-Acetyl Selank · Selank amidate
An anxiolytic heptapeptide analog of the immune peptide tuftsin, registered in Russia but not FDA-approved, with human anxiety data that is difficult to verify independently.
What the evidence says
Graded on the compound profile, not restated here.
Selank
An anxiolytic heptapeptide analog of the immune peptide tuftsin, registered as a medicine in Russia but not FDA-approved. Human anxiety data exists but sits mostly in Russian-language literature that is hard to independently verify.
- CPreliminaryAnxiety (generalized anxiety, adjustment/neurasthenia)Russian trials report benefit comparable to benzodiazepines; not independently verified.
- DPreclinicalCognitive / attention effectsEarly and mostly preclinical or small-study data.
- DPreclinicalGABAergic / neurochemical mechanismPreclinical mechanism, mainly in cells and rodents.
- UUnknownLong-term human safetyPoorly characterized outside Russian clinical use; no independent long-term data.
Selank sits in the same position as Semax and carries the same buying problem: real clinical use in one country, a research-chemical market everywhere else, and no connection between them.
The compound profile grades the anxiety evidence at C. That grade reflects studies run on a registered pharmaceutical preparation, and it does not transfer to an unverified vial.
Naming is the practical hazard
Plain Selank, N-Acetyl Selank, and the amidate form circulate interchangeably in listings. They are distinct molecules. A vendor that lists one name and ships another is not necessarily being deceptive — the market’s naming is genuinely sloppy — but the result is the same: you cannot map the literature onto what you received.
Require the sequence and the modification in writing on a lot-matched certificate. That single demand resolves most of the ambiguity, and a vendor unable to meet it has answered the underlying question.
The verification problem behind the grade
Most Selank human data sits in Russian-language literature that has not been independently replicated. The evidence article covers why that matters — it is not a claim that the work is wrong, but it does mean the usual cross-checks are unavailable.
Before you buy
- Distinguish Selank from N-Acetyl Selank and the amidate form — different molecules, sold under the same name.
- Require the full sequence and any modification on the COA, not just the product name.
- Confirm mass-spec identity; the modifications are what a substituted product would drop.
- Do not treat Russian registration as a quality signal for a grey-market vial.
What is sold
- Forms
- Lyophilized vial · Nasal spray solution
