Description
Selank 10mg — Product Identity and Format
The full sequence is Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). Each vial supplied by Core Research contains 10mg of Selank, verified by RP-HPLC to ≥99.0% purity with identity confirmed by ESI-MS. Batch-specific analytical documentation is available through the Core Research CoA Portal.
Selank is structurally related to tuftsin but is not tuftsin. Research evidence for tuftsin and research evidence for Selank are distinct and should not be conflated — tuftsin evidence does not directly support Selank claims without independent Selank data.

Frequently Asked Questions
Is Selank the same as tuftsin?
No. Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide derived from tuftsin (Thr-Lys-Pro-Arg) with a C-terminal PGP extension. The PGP extension is a synthetic modification not present in native tuftsin. Research evidence for tuftsin and research evidence for Selank are distinct and should not be conflated in research documentation or publications.
How does Selank differ from Semax?
Selank (tuftsin-PGP, TKPRPGP) and Semax (ACTH(4-7)PGP, MEHFPGP) are structurally distinct heptapeptides with different parent sequences and research contexts. Selank is derived from tuftsin; Semax is derived from ACTH(4-7). Both share the C-terminal PGP extension but differ in their core sequences and published research applications. Refer to the Selank vs Semax: Mechanisms and Research Applications guide for a detailed comparison.
Where can I access the Certificate of Analysis?
Batch-specific CoA documents are available via the Core Research CoA Portal.
