FST 344
€1,120.00
FST 344 is a peptide derived from follistatin, a natural protein that blocks myostatin and other TGF-β family members that limit muscle growth. By neutralizing these growth-limiting signals, FST 344 allows muscles to grow larger and stronger. Supplied as lyophilized powder with ≥98% purity (HPLC-verified).
How It Works
FST 344 binds to myostatin and activin A, preventing them from activating their receptors on muscle cells. Unlike ACE-031 which works at the receptor level, follistatin-based inhibitors work at the ligand level — catching the growth-limiting proteins before they can signal.
Research Data
- Muscle hypertrophy: Follistatin gene therapy in animal models has produced dramatic muscle growth, with some studies showing muscle mass increases of over 200% in targeted muscles.
- Satellite cell activation: FST 344 promotes muscle stem cell (satellite cell) proliferation and differentiation into new muscle fibers.
- Combined effects: Research shows both muscle fiber hypertrophy (existing fibers get bigger) and hyperplasia (new fibers form).
- Functional improvements: Treated animals demonstrate measurable increases in muscle force output and exercise capacity.
Research Applications
- Follistatin and myostatin pathway research
- Muscle stem cell biology and satellite cell activation
- Extreme muscle hypertrophy models
- TGF-β family signaling in skeletal muscle
Product Specifications

Community Buzz
FST 344 is the frontier of muscle-building science — an AAV gene therapy that delivers follistatin to permanently suppress myostatin, your body’s natural muscle-growth brake. The community treats it with a mix of awe and caution: remove myostatin, and muscles grow far beyond normal limits (as seen in rare natural myostatin-deficiency cases showing extreme hypertrophy). Unlike injectable peptides that wear off, AAV delivery could theoretically provide years of ongoing follistatin expression. Human data is extremely thin — mainly small trials for muscle-wasting diseases. Very high risk, very high theoretical reward.
Why People Are Interested
- Permanent myostatin suppression. One-time gene therapy could provide years of unblocked muscle growth potential.
- Anti-inflammatory and joint-protective effects. Animal models show reduced osteoarthritis progression.
⚠️ Extremely limited human data. Gene therapy carries unique and serious risks. This information is for awareness only.

All peptide products are supplied as a lyophilized (freeze-dried) powder in sterile glass vials. Lyophilization preserves the peptide's structural integrity and biological activity during transport and storage. The powder must be reconstituted with an appropriate solvent before use in research protocols.
Recommended Solvent
For most peptide research applications, we recommend using Bacteriostatic Water (BAC) — sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent. BAC water helps maintain sterility after reconstitution and is suitable for multi-dose research protocols.

Reconstitution Protocol
- Prepare: Clean your work surface and ensure all materials (vial, BAC water, syringes) are handled in a sterile manner.
- Calculate: Determine the desired concentration by dividing the peptide mass (mg) by the volume of BAC water added (mL). For example, adding 2 mL of BAC water to a 5 mg vial yields a concentration of 2.5 mg/mL.
- Reconstitute: Using a sterile syringe, draw the calculated volume of BAC water. Insert the needle through the rubber stopper at an angle and slowly inject the solvent down the inner wall of the vial — avoid directing the stream directly onto the powder to prevent foaming.
- Dissolve: Gently swirl the vial (do not shake) until the powder is fully dissolved. Most peptides dissolve within 1-2 minutes. A clear, colorless solution indicates complete dissolution.
- Aliquot: For long-term use, transfer the reconstituted solution into sterile aliquots to avoid repeated freeze-thaw cycles of the original vial.
Post-Reconstitution Storage
- Store reconstituted peptide solution at 2-8°C for short-term use (up to 7 days).
- For extended storage, aliquot and freeze at -20°C. Avoid repeated freeze-thaw cycles.
- Always label aliquots with peptide name, concentration, date, and storage conditions.
Note: The optimal solvent and reconstitution protocol may vary depending on the specific peptide and research application. Researchers should consult peptide-specific literature for solubility guidance.
