Thymalin reconstitution calculator
Type in a vial size, the diluent volume you added, and a dose figure — the calculator below converts those three numbers into a concentration, a draw volume, and a syringe reading. What it cannot do, for Thymalin specifically, is check that arithmetic against an FDA-approved product's own label, because no U.S. approval exists. Read why below — including a name mix-up worth clearing up before you use it.
Not FDA-approved — and not the same compound as Thymosin Alpha-1 or Beta-4
Thymalin is a polypeptide complex extracted from calf thymus tissue, developed by an independent Soviet research program in the 1970s. Despite the name-adjacent similarity, it is chemically distinct from Thymosin Alpha-1 and Thymosin Beta-4, both of which trace to a separate, parallel American research program from roughly the same era — this page and this site's Thymalin evidence review both state that distinction directly. Thymalin has no FDA-approved drug product: a direct check against DailyMed, the National Library of Medicine's official archive of FDA-approved drug labeling, returns zero results for "thymalin," and openFDA's Drugs@FDA and FAERS databases both return no matches. A live search of FDA's current 503A Bulks List and its companion significant-safety-risks page found no mention of it in either document.
Thymalin's real clinical use in Russia is intramuscular injection of a lyophilized powder, and a live vendor check found it consistently sold in the U.S. peptide-research market the same way: a 10mg lyophilized vial, reconstituted with bacteriostatic water or saline before use — the arithmetic this tool models.
What the tool below actually does is narrower than that context might suggest: it takes the vial size, diluent volume, and dose you type in and returns the concentration and draw volume that arithmetic implies — nothing more. It cannot confirm that a particular vial is what its label claims.
