TP-7 / TKPRPGPSelank research guide
Plain-language notes on Selank / TP-7 sequence identity, tuftsin-analog context, immune and monoamine marker records, GABA-interaction caveats, and lab-only handling boundaries.
01 - Short version
The quick read.
Plain-language context only. No preparation steps, no use instructions, and no product-effect claims.
New to Selank? Here's the short version. Selank is a synthetic heptapeptide also indexed as TP-7 and commonly written as TKPRPGP.
This guide keeps tuftsin-analog, enzyme, immune-marker, monoamine, BDNF, and GABA-interaction context separate from Form Laboratories product claims.
Lot identity, purity, appearance, and supplied form remain COA-led. Published papers are used only as scientific background.

Identity information lets you compare the guide with the product label. It is not a certificate, mixing method, or instruction for use.
03 - What studies look at
The main research themes.
Each note stays at study-context level and avoids use instructions.
01Enkephalin-degrading enzyme recordKost et al., Russian Journal of Bioorganic Chemistry, 2001.
The paper supports enzyme-system context for Semax and Selank.
02GABA ligand-receptor interaction recordVyunova et al., Neurochemical Journal, 2014.
The paper supports narrow GABA interaction language only.
03Structure-function reviewKoroleva and Mjasoedov, Biology Bulletin, 2019.
The review supports structure context while the guide keeps claims bounded.
Storage, appearance, purity, and release state come from the matching lot record.
Use the product label and matching COA as the authority for storage, appearance, purity, and release state.
This guide is educational context only. It does not include preparation, administration, human-use, or veterinary-use directions.
For laboratory research use only. 18+ only. Not for human consumption or veterinary use.
05 - FAQ
Common questions.
What is SELANK supplied for?
SELANK is supplied as laboratory research material only. It is 18+ only, not for human consumption, and not for veterinary use.
Does this page include matching COA information?
Yes. The product page lists lot, identity, purity, appearance, release status, and storage notes for SELANK.
How should the vial be handled after delivery?
Follow the label and matching COA paperwork. This page repeats 2-8 C storage guidance and light-protection notes before checkout.
What sequence identifies Selank?
The catalogue uses the seven-amino-acid sequence TKPRPGP, written in full as Thr-Lys-Pro-Arg-Pro-Gly-Pro.
Why is the GABA wording narrow?
The cited record supports ligand-receptor interaction research language. The page does not turn that into a broad product claim.
Can this be used outside a lab?
No. Selank from Form Laboratories is for laboratory research only, 18+ only, and not for human consumption.
