    Follistatin 344 Description

    Follistatin 344 was initially identified as a follicle-stimulating hormone inhibiting substance found in ovarian follicular fluid. FST is a high-affinity activin binding protein that can act as an activin antagonist. Two alternatively spliced follistatin mRNAs exist, encoding mature FS with 288 amino acid residues (FS-288) and 315 aa residues (FS-315). Natural FS purified from porcine ovaries is primarily a carboxy-terminal truncated form of FS-315 composed of 300 aa residues.

    Follistatin 344 quickly gained popularity in the bodybuilding community as a potential supplement to rapidly increase lean tissue mass. Another protein, follistatin-related gene acts on similar pathways as FST regarding its muscle building properties. Increased lean tissue mass could give a bodybuilder an advantage in a competitive setting.

    Follistatin 344 Storage

    Lyophilized Follistatin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FST should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
