ABOUT FOLLISTATIN-344
Follistatin-344 is a glycoprotein best known in research for binding and neutralising myostatin — the signalling protein that limits skeletal muscle growth. Models with myostatin inhibition show dramatic increases in lean tissue, which is why Follistatin-344 sits at the centre of modern muscle-hypertrophy research. One of the most sought-after single-compound vials in the performance category, supplied at 1mg with verified purity documentation.

Reconstitution guideSlowly inject the 1ml of bacteriostatic water down the inside wall of the Follistatin-344 vial (do not aim directly at the powder). Gently swirl — never shake — until fully dissolved. Refrigerate after reconstitution; use within 2 weeks. Draw 10 units on a U-100 insulin syringe for a 100mcg research dose.
