Gonadorelin- Summary
- Follistatin 344 is a recombinant form of the endogenous follistatin protein. It inhibits myostatin and activin — the primary negative regulators of muscle growth — potentially removing the genetic ceiling on muscle development. It is one of the most theoretically powerful anabolic compounds but is experimental with limited human data.
- Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
- Half-Life
- ~24–36 hours
- ~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
- Admin Route
- SubQ, IM
- SubQ, Intranasal
