Selank
Also known as: TP-7
A synthetic heptapeptide based on the immunomodulatory peptide tuftsin, extended with Pro-Gly-Pro for stability. Studied principally for anxiolytic-related effects.

Identifiers are published only with a source and a check date. Fields marked “not verified” have not yet been confirmed against a primary source — we show the gap rather than an unchecked figure. Always confirm against the certificate of analysis for the specific lot you hold.
Biological targets
- Reported GABAergic and monoaminergic modulation
Mechanism of action
Derived from tuftsin, a tetrapeptide fragment of immunoglobulin G, with the same Pro-Gly-Pro stabilising strategy used in Semax.
Research evidence and its limits
As with Semax, the literature is concentrated in a limited set of sources with sparse independent replication.
Safety considerations
No regulatory authority has assessed this compound as safe or effective for any human indication. The published record is predominantly laboratory and animal work, which does not establish human safety. Supplied and discussed here strictly as a laboratory research material. Not a medicine, not for human or veterinary administration, and nothing on this page should be read as a dosing, treatment or safety recommendation.
Analytical identification and quality testing
Identity by high-resolution mass spectrometry against the expected mass, purity by RP-HPLC with UV detection. Tandem MS sequencing or peptide mapping gives stronger identity evidence than mass alone.
Regulatory status
Has held regional regulatory status in Russia. Not approved by the FDA or EMA.

Semax
A synthetic heptapeptide derived from a fragment of ACTH with a C-terminal Pro-Gly-Pro extension that confers enzymatic stability. Developed and studied largely in Russia, where it has had regional regulatory status.
Delta sleep-inducing peptide (DSIP)
A nonapeptide originally isolated from rabbit cerebral venous blood during induced sleep states. Despite the name, its role in sleep regulation has never been firmly established.
