Overview of Follistatin

Follistatin (FST) is a secreted glycoprotein that binds and inhibits members of the TGF-β superfamily, most notably myostatin (GDF-8) and activin. The FST-344 variant represents the full-length circulating form. As a potent myostatin inhibitor, Follistatin has been the subject of extensive research in skeletal muscle biology, with studies consistently showing dramatic effects on muscle mass in research models.

Each vial available from SteroidsCanada.ca contains 1mg of lyophilized Follistatin, manufactured to rigorous pharmaceutical-grade standards and independently verified for purity exceeding 98% via HPLC analysis. This makes it an ideal choice for qualified researchers and laboratory professionals seeking dependable, high-quality peptides for myostatin inhibitor research applications.

Mechanism of Action

Follistatin’s primary research mechanism is its high-affinity binding to myostatin, preventing myostatin from activating its receptor (ActRIIB). Since myostatin is a powerful negative regulator of muscle growth, its inhibition removes the brake on muscle development. Follistatin also binds activin and regulates follicle-stimulating hormone (FSH) pathways, making it a multifunctional research tool.

Reconstitution Guidelines

Follistatin is supplied as a lyophilized (freeze-dried) powder that must be reconstituted with sterile bacteriostatic water (0.9% benzyl alcohol) before use in research applications. The recommended reconstitution volume for this vial is 1mL of bacteriostatic water, which yields a concentration suitable for precise research dosing.

Reconstitution Best Practices

• Use sterile bacteriostatic water (0.9% benzyl alcohol preservative)
• Add diluent slowly along the vial wall — never directly onto the peptide cake
• Gently swirl to dissolve — never shake the vial vigorously
• Allow the peptide to fully dissolve before drawing any dose
• Store reconstituted vials at 2–8°C (refrigerator)
• Use reconstituted peptide within 28–60 days depending on specific research requirements
• Always use sterile technique when drawing from the reconstituted vial

Research Protocol Guidelines

Research protocols use relatively small doses (10-100mcg) due to Follistatin’s potent activity. Typically 10-day research cycles.

Typical Research Timeline

• Day 1-5: Initial myostatin binding research phase
• Day 6-10: Peak research cycle activity
• Day 11-20: Typical wash-out period between cycles
• Month 2+: Extended research cycle planning

Individual research results vary based on protocol design, specific research objectives, and research model characteristics. The above timeline represents commonly observed patterns in published research literature.

Research Stacking Protocols

In research applications, Follistatin is often studied in combination with complementary research peptides to investigate pathway interactions. Common research combinations include:

• Follistatin + IGF-1 LR3: Complete muscle research protocol
• Follistatin + BPC-157: Muscle + repair research
• Follistatin alone: Pure myostatin research

Any research stacking protocol should be designed based on specific investigative objectives and informed by current scientific literature.
