What Is Selank? The Tuftsin-Analog Peptide Explained
Selank is a synthetic heptapeptide based on tuftsin, sold for laboratory research use only. Here is what it is and how to verify a COA.
Selank is a synthetic peptide based on the naturally occurring immune peptide tuftsin. It is a seven-amino-acid peptide, and like Semax it was developed in Russia.
Research-use status
Published literature on Selank is mostly animal work from Russian institutions, and this page does not summarise effects or uses. Selank is a synthetic analog of tuftsin and is often listed alongside Semax, as both come from the same Russian research lineage. It is also commonly sold as the longer-acting N-Acetyl Selank Amidate.
Selank versus N-Acetyl Selank Amidate
As with Semax, vendors frequently sell a modified N-Acetyl Selank Amidate that is engineered for greater stability and duration. Confirm which form a product is when comparing across vendors.
What to check on a Selank COA
Look for a named lab, mass-spec identity confirmation, HPLC purity with decimals, the exact form, a matching batch, and a recent test date.
Frequently Asked Questions
Is Selank related to Semax?
They are different peptides but share a Russian research lineage. Selank is based on tuftsin; Semax is based on an ACTH fragment.
What is N-Acetyl Selank Amidate?
A modified, more stable and longer-acting version of Selank that many vendors sell. Confirm which form is being offered.
What should a Selank COA include?
A named lab, mass-spec identity, HPLC purity with decimals, the specific form, a matching batch, and a recent date.
