Selank price comparison

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the endogenous peptide tuftsin. It exists as a research-use-only (RUO) compound and has been examined in laboratory and preclinical models within research on anxiety-related and cognition-related behavior. It is frequently referenced alongside Semax in preclinical peptide literature. This index tracks research-use-only vendor pricing for Selank so researchers can compare cost across suppliers.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mg — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.

Why compare $/mg for Selank?

Per-mg pricing for Selank varies across vendors because of differences in synthesis scale, stated purity, lot testing overhead, fill quantity per vial, and how each supplier prices bulk versus single units. Comparing normalized $/mg across vendors lets a researcher see the true cost of the material rather than the headline vial price, and flags outliers that may reflect lower purity or unverified sourcing.

Reading the COA

For Selank, confirm identity by mass spectrometry against the expected monoisotopic mass for the heptapeptide sequence (Thr-Lys-Pro-Arg-Pro-Gly-Pro, C33H57N11O9, ~751.9 g/mol) and check that HPLC purity is stated at 98 percent or higher for the main peak. Because Selank is proline- and arginine-rich, watch for truncated or deletion sequences and residual TFA counterion from synthesis reported on the COA. Verify the lot number and test date on the certificate match the vial you received rather than a generic reference document. COA review is for confirming the identity and purity of the material only.

FAQ

How is lyophilized Selank typically stored and handled in a research setting?
As a lyophilized powder, Selank is generally kept sealed and protected from light, moisture, and heat, with long-term storage in a freezer; short handling periods at refrigerated or room temperature are common for research workflows. This is general material-handling information for the compound as a laboratory reagent, not use guidance. Always follow the storage conditions printed on the specific vendor's COA or product documentation.
What is a COA and what should I check on it for Selank specifically?
A Certificate of Analysis (COA) is the vendor's lot-specific test report documenting the identity and purity of the material. For Selank, check that mass spectrometry confirms the expected mass of the heptapeptide sequence, that HPLC purity is reported (commonly 98 percent or higher), and that the lot number, test date, and quantity match your vial. The COA verifies what the material is, not any outcome.
Why do per-mg prices for Selank differ so much between vendors?
Differences come from synthesis batch size, stated purity grade, the amount of quality-control testing behind each lot, vial fill quantity, and packaging or bulk-discount structures. A lower headline price can reflect a smaller fill or less rigorous testing, which is why normalizing to $/mg and reviewing each vendor's COA gives a clearer comparison of value for research-use-only material.
