Description

FST 344 is a recombinant form of follistatin — a naturally occurring glycoprotein that functions as a potent myostatin inhibitor. Supplied as a lyophilized research-grade compound for use in controlled research environments, it is widely investigated in skeletal-muscle and growth-axis research models for its capacity to bind and neutralize myostatin.

About FST 344 / Follistatin (1mg)

Follistatin acts as a molecular "decoy" — binding myostatin and other TGF-β superfamily ligands and preventing them from activating their receptors. In preclinical research models, this is one of the most powerful anabolic signaling tools studied, frequently producing dramatic shifts in muscle-growth markers.

What It's Being Studied To Do

  • Increase skeletal-muscle mass and strength markers in research models by removing myostatin's natural inhibitory signal
  • Promote muscle-fiber hypertrophy and potential hyperplasia in research models
  • Preserve lean-mass markers during catabolic-state research models
  • Examine functional-performance changes in research models
  • Investigate secondary effects on bone-density markers downstream of increased muscle

Why It Matters in Research

Myostatin is the body's built-in limiter on muscle size — a research-relevant target in studies of sarcopenia, cachexia, and muscle-wasting research models. FST 344 research explores how neutralizing this signal alters muscle-development pathways at the tissue level.

  • HGH / IGF-1 LR3 — synergistic growth-signaling research
  • PEG-MGF — localized muscle-repair research
  • AOD-9604 — adipose-balance research

Storage Instructions

All products from Rhema Research Labs are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥99%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥99% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

  • Maximum stability: Extended shelf life compared to liquid solutions
  • Precise measurement: Researchers can work with desired quantities
  • Contamination protection: Sealed vials prevent environmental exposure
  • Shipping durability: Powder form is more stable during transit

Lyophilized peptides:

  • Store at -4°F for long-term storage (up to 24 months)
  • Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
  • Keep away from light, moisture, and repeated temperature fluctuations

We supply research-grade peptides to:

  • Academic and university research laboratories
  • Pharmaceutical and biotechnology companies
  • Independent research institutions
  • Licensed professionals conducting legitimate scientific research

We maintain rigorous quality control through a multi-step verification process:

  • HPLC Analysis: Every batch tested to verify ≥99% purity
  • Mass Spectrometry: Molecular weight confirmation for peptide identity
  • Third-Party Testing: Independent laboratory verification
  • Sterility Protocols: Aseptic handling and packaging procedures
  • Batch Documentation: Complete traceability from synthesis to delivery

"Research Use Only" (RUO) is a classification indicating that a product is intended exclusively for laboratory research and experimental investigation.

All orders are shipped with research-grade handling protocols:

  • Packaging: Insulated containers with cold packs when required
