Buy Follistatin-344 Peptide: A Comprehensive Research Overview

What Is Follistatin-344?

Buy Follistatin-344 is a synthetic, full-length version of the naturally occurring Follistatin protein, playing a critical role in muscle growth, metabolic regulation, and cellular repair. It exists in two primary isoforms:

• FST-344 (315 amino acids) – The predominant form, making up ~95% of Follistatin mRNA transcripts in most tissues.
• FST-317 (288 amino acids) – A minor variant, accounting for less than 5% of total Follistatin activity.

The numerical designations (344 vs. 317) refer to the precursor molecule lengths before post-translational modifications.

Follistatin-344 is a full-sized synthetic analogue of naturally occurring Follistatin. It neutralizes the effects of myostatin, activin, and follicle stimulating hormone (FSH). In animal studies, these actions lead to increased muscle mass (both hypertrophy and hyperplasia), reduced scar formation, and inhibited certain inflammatory responses. Follistatin-344 can be altered by the body to produce other variants of Follistatin.

Why Follistatin-344?
✔ Natural protein analog (lower immunogenicity risk)
✔ Broad-spectrum TGF-β inhibition (beyond just Myostatin)
✔ Emerging human trial data (safer than synthetic alternatives)

Mechanism of Action: How Follistatin-344 Works

Follistatin-344 primarily functions as a binding inhibitor of the TGF-β (Transforming Growth Factor-beta) superfamily, which includes:

• Myostatin – A key regulator of muscle growth inhibition.
• Activin – Influences reproductive health, inflammation, and fibrosis.
• FSH (Follicle-Stimulating Hormone) – Critical for fertility and gonadal function.

By neutralizing these inhibitory signals, Follistatin-344 promotes:
✅ Muscle hypertrophy & hyperplasia (via Myostatin suppression)
✅ Enhanced insulin/IGF-1 signaling (improving glucose metabolism)
✅ Tissue regeneration & anti-fibrotic effects (through Activin modulation)

Latest Research & Potential Applications (2024 Updates)

1. Muscle Growth & Performance Enhancement

• A 2023 study in Nature Cell Biology demonstrated that Follistatin-344 increased muscle mass by 30% in murine models without exercise.
• Human clinical trials (Phase II) are investigating its potential for sarcopenia and muscular dystrophy treatment.

2. Metabolic & Anti-Diabetic Effects

• Research in Diabetes & Metabolism (2024) found that Follistatin-344 improves insulin sensitivity by upregulating GLUT4 transporters in skeletal muscle.
• May offer therapeutic benefits for Type 2 Diabetes & metabolic syndrome.

3. Reproductive Health & Fertility

• By modulating Activin & FSH, Follistatin-344 shows promise in:
  • PCOS (Polycystic Ovary Syndrome) – Reduces ovarian fibrosis.
  • Male infertility – Enhances spermatogenesis in preclinical models.

4. Anti-Fibrotic & Wound Healing Properties

• A 2024 study in The Journal of Clinical Investigation reported that Follistatin-344 reduces liver and lung fibrosis by blocking TGF-β signaling.
• Accelerates tissue repair in chronic wounds by promoting angiogenesis.
