SELANK FAQ

Where do I buy Selank online?

Selank is available from Blank Peptides in 10mg vials, produced in our cGMP labs in the USA and shipped with a lot-matched certificate of analysis. There is no prescription requirement and no approval queue for research material. Processing time is within 1 business day, with tracking emailed once the label prints.

What is Selank?

Selank is a synthetic heptapeptide derived from tuftsin, an immune-active fragment of the IgG heavy chain, with a Pro-Gly-Pro sequence added for stability. Research has examined GABAergic and serotonergic signalling, BDNF expression and anxiolytic behaviour in rodent models. Most of the primary work comes out of Russian institutes.

Is your Selank tested for purity?

Yes, to greater than 99%. In-house HPLC and mass spectrometry establish identity and purity, then an independent laboratory, either Freedom Diagnostics or Horizon Analytical, repeats the analysis. Every batch also passes bacterial endotoxin testing before release, and Blank Peptides publishes the resulting COA against your specific lot.

How much bacteriostatic water for Selank 10mg?

1mL, our standard ratio across the catalogue, producing a 10mg/mL solution. Add the water gently against the vial wall and swirl rather than shake. The cake usually goes clear within seconds. If you need finer measurement resolution on small draws, a 0.3mL insulin syringe is the practical tool.

Selank vs Semax: how do researchers choose?

They come from different parent molecules and appear in different bodies of work. Selank traces back to tuftsin and its literature is anxiolytic and GABAergic. Semax traces back to ACTH, with research centred on BDNF and dopamine pathways. Comparative studies often run both because the contrast is what makes the design interesting.

How should Selank be stored?

Lyophilized and sealed at -20C, protected from light and moisture. Ambient transit temperatures are fine. Once reconstituted, keep the vial at 2 to 8C and use within a few weeks. Avoid freezing and thawing solution repeatedly; short peptides lose integrity faster under cycling than most people assume.

Do you sell Selank nasal spray?

Not currently. We supply Selank as a lyophilized powder in 10mg vials for laboratory reconstitution, which gives researchers control over concentration and solvent. If demand for other research formats grows we will look at it, but the vial is what is listed today.

Is Selank legal to buy in the US?

Selank is sold here as a research chemical, not a medicine. It has no FDA approval, is not a supplement or veterinary product, and is not for human use. It is a registered pharmaceutical in Russia, which does not change its status in the United States. Ordering confirms laboratory research use.
