Follistatin-344 Peptide – User Manual & Dosage Protocol Guide

Follistatin-344 is a recombinant protein studied for its ability to bind and inhibit myostatin and activin, regulatory proteins involved in muscle growth signaling. In research settings, it is used to investigate muscle hypertrophy pathways, tissue regeneration, and anabolic signaling.

Research Applications

• Myostatin inhibition and muscle growth models
• Tissue regeneration and repair studies
• Activin signaling pathway research
• Body composition and performance physiology models

Disclaimer: Follistatin-344 is for research and experimental use only and is not FDA-approved for therapeutic use.

Lyophilized Powder

Freeze-dried Follistatin-344 intended for reconstitution prior to use in research settings.

Reconstituted Solution

Prepared liquid form used as an injectable research preparation after proper reconstitution.

Follistatin-344 is studied for its ability to:

• Bind and neutralize myostatin, removing inhibitory signals on muscle growth
• Modulate activin signaling pathways
• Promote muscle fiber growth in experimental models
• Support tissue repair and regenerative signaling

Observed effects are primarily from preclinical and investigational protocols.

Subcutaneous (SC) – Standard Research Model

Typical research protocols use 100–300 µg per administration, usually once daily, often in muscle signaling research models.

Short-Course Research

Some studies use 100–200 µg daily in limited-duration research protocols.

Administration Method

Most research models utilize subcutaneous (SC) administration for controlled delivery.

Important

There is no approved human dosage. The ranges above reflect commonly cited research patterns only.

Initiation

A 1-week phase used for initial response observation in the research model.

Active Study Phase

Typically 10–30 days, focused on evaluating myostatin pathway activity.

Rest Period

A 4+ week interval between study cycles to allow recovery and system reset.

Note

Cycle duration may vary depending on the study design and research endpoints.

Supplies

• Sterile bacteriostatic water
• Sterile syringe
• Alcohol swabs

General Procedure

1. Clean vial stopper with alcohol.
2. Add bacteriostatic water to desired concentration.

• Example: 1 mg vial + 1 mL → 1 mg/mL

1. Swirl gently to dissolve (do not shake).
2. Refrigerate at 2–8°C after reconstitution.
3. Use within 2–4 weeks or per protocol.

Injection Model

• Common sites: abdomen, thigh, upper arm
• Maintain sterile technique
• Rotate sites to minimize irritation

Lyophilized Powder

Store in a cool, dry environment to maintain stability, with a shelf life of up to 12 months.

Reconstituted Solution

Keep refrigerated at 2–8°C and use within 2–4 weeks after preparation.

Protection Guidelines

Protect from light, heat, and contamination to preserve quality.

Safety Note

Discard the solution if it becomes cloudy or discolored, as this may indicate contamination or degradation.

• Research use only
• Not for therapeutic application
• Potential research observations: injection-site irritation
• Maintain sterile handling technique
• Keep out of reach of children

Human safety outside controlled research is not established.
