Selank 5mg Lab Grade Research Peptide — 99%+ Purity
Selank 5mg, the synthetic heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro (a tuftsin analog) supplied as a lyophilized powder for laboratory research. HPLC and mass-spec verified, lot COA included.
What is Selank?
Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro: the natural tuftsin sequence (Thr-Lys-Pro-Arg) extended with a Pro-Gly-Pro tail that slows its breakdown. It was developed in Russia and is studied mostly in rodent and cell models.
This vial holds 5mg as a lyophilized powder. Each lot is HPLC and mass-spec tested, and the lot COA ships with your order. Its sister peptide is Semax 10mg.

Why Buy Selank from CoreVionRX?
Detailed Description
Selank 5mg is a synthetic seven-amino-acid peptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), supplied as a lyophilized powder for laboratory research. It was developed in Russia as a more stable analog of tuftsin, a short peptide that occurs naturally in the body.

Selank vs Semax
Selank and Semax are sister peptides from Russian research. Both end in the same Pro-Gly-Pro tail, added to slow their breakdown. The front half differs: Selank starts with tuftsin (Thr-Lys-Pro-Arg), while Semax starts with a fragment of ACTH (Met-Glu-His-Phe). Semax is C37H51N9O10S, 813.9 g/mol, so the lot COA's mass confirms which one a vial holds.
What published studies examined
- Behavioural studies in rodents
- Gene-expression studies in rodent brain tissue
- Enzyme studies of how Selank affects the breakdown of enkephalins (in vitro)
- Small clinical studies published in Russia
Most of the literature comes from a few Russian groups, and independent human data are limited. Selank is not an FDA-approved drug.
Verified before it ships
Every lot is tested by an independent lab before it reaches our shelf: HPLC for purity and mass spectrometry for identity. The lot-specific Certificate of Analysis ships with your order, so you can match the number on your vial to the data.
Storage
- Sealed vial: store frozen at -20°C, away from light and moisture.
- Once dissolved for lab work: keep refrigerated at 2–8°C.

Frequently Asked Questions About Selank
Common questions from researchers buying Selank for laboratory studies.
What is Selank?
Selank is a synthetic seven-amino-acid peptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is an analog of tuftsin with a Pro-Gly-Pro tail added for stability, developed in Russia.
What is in the Selank 5mg vial?
One sealed glass vial holding 5mg of Selank as a lyophilized powder. Formula C33H57N11O9, molecular weight 751.9 g/mol, CAS 129954-34-3.
What is the difference between Selank and Semax?
Both are Russian-developed peptides ending in Pro-Gly-Pro. Selank is built on tuftsin (Thr-Lys-Pro-Arg); Semax is built on an ACTH fragment (Met-Glu-His-Phe). They have different masses, which the lot COA shows.
How should Selank 5mg be stored?
Keep the sealed vial frozen at -20°C, away from light and moisture. Once the powder is dissolved for lab work, keep the solution refrigerated at 2–8°C.
