Selank reference material, supplied as a lyophilized powder in a sealed vial for in-vitro laboratory research and analytical method development. Each fill size is a separate SKU. Lot and COA records are shown when assigned.
This listing is a research chemical / reference material. No therapeutic, preventive, or diagnostic claims are made or implied. The storefront displays only approved analytical characterization data released through its public report records.
Selank is a heptapeptide, tuftsin-derived of 7 amino acids. Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). Derived from tuftsin, an endogenous immunomodulatory tetrapeptide.
Reported to interact with the GABAergic system. Vectra makes no claim as to mechanism or effect.
Engineered at the Institute of Molecular Genetics of the Russian Academy of Sciences, and clinically approved and used in Russia. No Western randomised controlled trial data is on record in our sources. First described by Institute of Molecular Genetics, Russian Academy of Sciences.
Studied in GABAergic signalling and anxiolytic models. Vectra supplies it as a reference material for in-vitro laboratory research and analytical method development only.
As with Semax: approved clinical use in one jurisdiction, no Western trial record. Preclinical models report effects comparable to diazepam without sedation, dependence, or memory impairment — a preclinical comparison, not a clinical one.
Specific clinical adverse-event rates are not recorded in our sources.
Our sources carry no CAS number, molecular formula, molecular weight, or storage data for Selank.
Not approved as a medicinal product in the United States. No therapeutic, preventive, or diagnostic claims are made or implied.
These are the specific, documented failure modes that lot-level third-party analysis addresses. A report reachable from the lot code printed on the vial — without asking the seller for it — is the only document that answers 'is this vial what the label says'. That is why every Vectra vial carries a QR code resolving to its own lot's published report.
Findings reported by commercial testing providers. Each names its source; none is registry- or peer-review-grade, so read them as a documented pattern rather than established prevalence.
Yes, and altered certificates have been reported in this market at material rates — see the testing findings above. Three properties make a report hard to fake:
Peptide identity data in the vendor market is often wrong in ways that are hard to see. Near-identical compounds get their CAS numbers, residue ranges, formulas and molecular weights swapped. A certificate can be internally consistent and still describe a different molecule than the label names. Most commercial peptide material ships as an acetate salt, not free base. The two forms have different measured masses, so a figure quoted against the wrong one will not reconcile. A report that does not state which form it assayed cannot be checked at all.
The standard our own reports are built to meet:
FDA has acted in this market between 2024 and 2026. Actions include a civil forfeiture over $1.7 million against a compounding operation, several rounds of warning letters to peptide vendors, and more than thirty letters in March 2026 concerning compounded GLP-1 products.
Buyers here increasingly compare document trail, not price.
Compatibility does not assert current availability. No preparation, ratio, or protocol guidance renders here.
