Follistatin 315 is the primary active circulating isoform of the follistatin protein. It plays a key role in regulating muscle growth by naturally inhibiting myostatin and activin, two proteins that limit muscle development. At Peptide Union, we offer high-purity research-grade Follistatin 315 in convenient lyophilized vials for those seeking quality peptide products.

• We source Follistatin 315 as a 315-amino-acid chain that circulates effectively in the bloodstream, making it one of the most bioavailable forms available for research purposes.
• This isoform binds directly to myostatin to prevent it from restricting muscle cell growth and differentiation, supporting greater muscle-building potential.
• Our product maintains high purity levels with batch testing to ensure consistency and reliability for laboratory and research applications.
• Follistatin 315 occurs naturally in the human body, and researchers study it extensively for its role in muscle regulation, metabolism, and tissue health.
• We provide sterile, sealed vials that preserve the peptide’s stability until reconstitution, giving you a ready-to-use research compound.
• Customers choose our Follistatin 315 for its targeted action and our commitment to discreet, reliable worldwide delivery with full tracking.
• Our team ensures every vial meets strict quality standards so you receive a consistent product for your specific research needs.

 Follistatin 315 supports muscle growth primarily by inhibiting myostatin, the protein responsible for setting natural limits on muscle size and strength. By blocking myostatin’s activity, it allows muscle cells to grow larger and recover more effectively. We supply premium Follistatin 315 to researchers exploring these performance and development pathways.

• It neutralizes myostatin in the bloodstream, removing a major brake on muscle hypertrophy and enabling enhanced muscle fiber development.
• Researchers observe increased muscle mass and strength gains in studies involving follistatin due to improved protein synthesis and cell proliferation.
• Follistatin 315 also modulates activin signaling, which further promotes lean tissue growth while helping maintain balanced body composition.
• Our high-purity version ensures reliable inhibition activity, making it a preferred choice for those studying muscle-building mechanisms.
• Many users report interest in its potential to accelerate progress toward strength and physique goals when used in controlled research settings.
• We emphasize proper storage and handling so the peptide retains its full potency for accurate research outcomes.
• The systemic circulation of Follistatin 315 allows it to affect muscles throughout the body, unlike more localized alternatives.

•  Follistatin 315 is the mature, active circulating form of the protein, while Follistatin 344 is the longer precursor isoform that the body processes into the active 315 version. We offer both at Peptide Union so researchers can select the exact form that matches their study requirements.

  • Follistatin 315 works directly in the bloodstream with higher systemic bioavailability and faster action on muscle tissue.
  • Follistatin 344 contains 29 additional amino acids and often serves as a precursor that converts to the 315 form in the body.
  • The 315 isoform shows better stability in extracellular fluid, making it ideal for studies focused on overall muscle regulation.
  • Researchers select 344 when exploring gene therapy or localized effects, while 315 suits broader performance and recovery investigations.
  • Our manufacturing process delivers clear distinctions in purity and labeling so you always know which isoform you receive.
  • Both forms inhibit myostatin effectively, but 315 provides more consistent circulating levels for systemic research goals.
  • We maintain stock of both variants with full specification details to help you compare and choose confidently.
