Dosage Protocols

FormDoseRouteCycle
Follistatin-344100–200 mcg/daySC injection10–30 days

Follistatin is a protein (not a small peptide) and requires careful handling. Doses are based on research community protocols — no clinical dosing guidelines exist for muscle growth applications.

Reconstitution

Reconstitute lyophilized follistatin with bacteriostatic water. The protein is temperature-sensitive — inject bacteriostatic water gently down the side of the vial. Do not shake. Use the peptide calculator for volumes.

Timing & Cycles

Research protocols typically run 10–30 day cycles. Some protocols recommend breaks between cycles. Follistatin-344 is cleaved to active forms (FS-315, FS-288) after administration, with effects on myostatin persisting beyond the active compound half-life.

Storage

  • Lyophilized: -20°C or colder for long-term
  • Reconstituted: 2–8°C, use within 7–14 days (less stable than small peptides)
  • Temperature-sensitive — avoid any exposure to room temperature when possible
