Follistatin / ACE-031
Experimental myostatin inhibitors — follistatin-based agents and ACE-031, a soluble activin receptor — aimed at removing the brake on muscle growth. Human use is investigational.

What Follistatin / ACE-031 is used for
- Inhibiting myostatin can drive substantial muscle growth in animal models
- ACE-031 trials showed increased muscle mass in early human dosing
How it's typically used
Reported experimental ranges are on the order of 100 mcg daily, with no established safe protocol.
What to watch for
- ACE-031 human trials were halted over vascular and bleeding-related side effects
- Effects and long-term safety in humans remain poorly understood
- Not approved for human use; experimental research-only agents banned in sport
About Performance & GH
- What they are
- Growth-hormone secretagogues and related performance compounds. Rather than supplying GH, they push your pituitary to release more of its own in a pulse.
- How they're run
- Subcutaneous injection, most often at night on an empty stomach so the pulse lands with natural sleep-driven GH release.
- What to watch
- Water retention, tingling hands, and hunger swings are the common early signs. Raising GH raises IGF-1 — worth tracking on bloodwork, and a reason to avoid these with any cancer history.
