## FAQ

### What is Selank's regulatory status in the United States?

Selank is not FDA-approved in the US and is classified as a Category 2 bulk drug substance as of 2026, prohibiting compounding pharmacy use while FDA review is ongoing; it is restricted to investigational research only.

### What is the amino acid sequence of Selank?

Selank's sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro, a 7-residue synthetic peptide derived from tuftsin, with additional amino acids incorporated to improve metabolic stability compared to the parent compound.

### Is Selank listed on the WADA Prohibited List?

Selank is not listed by name on the WADA Prohibited List, but as an unapproved substance it may fall under the S0 Non-Approved Substances catch-all category; athletes subject to doping controls should treat it with caution.
