Published research contexts for Follistatin-344 describe 100–300 mcg per administration. Descriptive only, not a recommendation.
Native follistatin clears on a minutes-to-hour scale; the injected product's human pharmacokinetics are not established.
A myostatin- and activin-binding protein studied in animal muscle models; no human dose-ranging study fixes an injected amount or schedule, so no schedule table is shown.
