What is Selank?
N-acetyl and amidate versions have their own cards. Those changes are not proven matches. Nasal research solutions and freeze-dried vials are different products.
Tuftsin-derived research peptide studied in GABA-related gene expression.
Regulatory status, dated 2026-10-09
Compounding
not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.
Research
investigational. Preclinical findings do not establish human anxiety-treatment efficacy.
Sport
unknown. Not individually verified; consult the current sport rules. Absence of a listing is not permission.
What the cited papers actually measured
Papers such as PMID 18479057 and 20931363 discuss GABA-related and calm models, often outside US Phase 3 programs. That is not product approval. It is not a diagnosis-to-treatment bridge. Community use does not raise the evidence grade. This catalog does not record a US drug approval. A forum thread that calls Selank a finished anxiety drug is ahead of every US approval record on this card.
We mark the cited papers as C. That is our label for how strong those papers are. It does not say the compound works.
human-trial
Authors reported similar anxiety improvement to medazepam and antiasthenic effects.
62 patients with generalized anxiety disorder or neurasthenia; 30 Selank and 32 medazepam. Small historical active-comparator study without placebo; blinding and long-term safety detail are limited. Findings do not transfer to N-acetyl/amidated analogues.
How long it lasts, how you store it, listed sizes
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
The chart uses the 10 mg listing. Modified selank cards keep their own sizes.
U-100 math for listed Selank sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 10 mg | 100 | 50 | 33.3 |

Questions people ask
Is Selank approved for anxiety?
This source set shows no US drug approval. Cited papers are not a diagnosis or a prescription.
Should I use the N-acetyl page instead?
Use the card that matches the name on your vial. This calculator is for the selank id. Open the acetylated card when that is the name on the vial.
