• 98%+ Purity Bodybuilding PeptideFST-344 Follistatin 344 (1mg / vial)

  Follistatin 344 Description

  Follistatin 344 was initially identifed 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 FSwith 288 amino acid residues(FS-288) and 315 aa residues (FS-315).Natural FS purifed 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 leantissue mass. Another protein, follistatin-related gene acts on similar pathways as FSTregarding 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-18C.Upon

  reconstitution FST should be stored at 4°C between 2-7 days and for future use below-18C. For long term storage it is

  recommended to add a carrier protein(0.1%HSA or BSA). Please prevent freeze-thaw cycles
