What you are paying for with Selank
Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin, developed in Russia. It is studied for anxiolytic (anti-anxiety) and cognitive endpoints without the sedation associated with classic anxiolytics. Because of that, the cost of Selank reflects more than raw material. Selank research focuses on modulation of GABAergic and monoamine signaling and on brain-derived neurotrophic factor (BDNF) expression, with interest in anxiety and focus endpoints.
What drives Selank pricing
Three things move the price of Selank most. First, vial size: Selank is cataloged in 5 mg vial, 10 mg vial, and a larger vial holds more peptide, so it costs more per unit even at the same per-mg rate. Second, purity and testing: genuine third-party verification to a 99%+ target with a Certificate of Analysis is a real production cost, and it is what makes a research result trustworthy. Third, quantity: ordering Selank in bulk or on a recurring research schedule lowers the effective per-vial cost.
Cost per milligram
Comparing peptides on price alone is misleading because vial sizes differ. The fair comparison is cost per milligram of verified peptide. When you evaluate Selank, divide the vial price by its milligram content and compare like-for-like against other 99%+ third-party-tested material - not against unverified powder that happens to be cheaper.
Getting the best value on Selank
Selank can be ordered as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months), and bulk or standing-order pricing is available for research programs. The best value is not the lowest sticker price - it is the lowest cost per milligram of documented, third-party-tested Selank, which is the standard every Peptides Factory Direct lot is held to.
Frequently asked questions
How much does Selank cost?
Selank typically ranges from $35 to $90 per vial at research-market pricing, depending on vial size. All Peptides Factory Direct Selank is third-party tested to a 99%+ purity target with a COA on request. Research use only.
Why does Selank pricing vary between suppliers?
Differences come down to purity and documentation. Material with genuine third-party COAs, lot tracking, and identity confirmation costs more to produce than unverified powder. The fair comparison is cost per milligram of verified peptide, not sticker price.
Is cheaper Selank a good deal?
Not if it lacks a Certificate of Analysis. Across the research-supply market the strongest trust signal is verifiable third-party purity testing. Unverified Selank can cost far more in failed experiments than the few dollars it saves.
Can I get bulk pricing on Selank?
Yes. Selank is available for one-time or recurring research orders, and bulk or standing-order pricing is available for research programs - note it on your order or open the portal.
