Selank 10 mg reconstitution calculator

Unlike semax and epitalon, selank has no FDA review that cites solubility or storage reports, and we found no primary source that says how much water 10 mg dissolves in or how long it keeps once mixed. The arithmetic still holds: 10 mg in 1 mL is 10 mg/mL (100 mcg per unit), in 2 mL 5 mg/mL (50 mcg per unit) and in 2.5 mL 4 mg/mL (40 mcg per unit). Whether the powder dissolves fully at those strengths isn’t documented. Swirl gently, don’t use it if the liquid stays cloudy or has particles, and follow the general advice in how to store peptides and how long reconstituted peptides last.

Selank turns up both as powder and as sprays. Belgian regulators’ lab found selank and semax in seized “suspicious preparations” in 2017 and 2018, and reported that these peptides “are freely available either as lyophilized powder for injection purposes or are present in nasal sprays” (Drug Test Anal, 2020). This page is for a 10 mg powder vial mixed with water and measured in syringe units. A spray is already a liquid with its own strength: don’t add water to it, and syringe units don’t apply. The authors call these products “potentially dangerous molecules”.

Selank is registered as an anxiolytic in Russia (Pharmaceutics, 2022), but it isn’t FDA-approved, so no US label sets a water volume or checks the 10 mg on the vial (see the status below). The FDA says compounded selank acetate “may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities”, and that it “lacks important information regarding any safety issues raised by selank acetate administered to humans” (FDA). The calculator can only work from what your label says, so ask a pharmacist before mixing.
