ACE-031 Dosage & Reconstitution Guide
⚠ ACE-031 (a decoy activin receptor) had its human trials halted over vascular and bleeding side effects. That is the headline fact any dosing page must lead with.

Dosing schedule
The table below reports the doses used in the underlying research or by the community — it is documentation, not a recommendation to replicate at home.
| Phase | Dose | Notes |
|---|---|---|
| Halted trials | 0.02 mg | 0.02–3 mg/kg single subcutaneous doses (discontinued) |
Timing & cycling
Trials used single or spaced subcutaneous doses scaled to body weight; development was discontinued.
Cycle length. None — the clinical program was stopped.
Storage & handling
Keep the lyophilized (unmixed) vial refrigerated at 2–8 °C (36–46 °F) in a dry, dark place — it tolerates short periods at room temperature during shipping. Once reconstituted, store it at 2–8 °C, never frozen, and use it within about 2–4 weeks (sooner if the solution turns cloudy or discolored). Swab the stopper before every draw and use a fresh needle each time.
Key points
- Blocks myostatin and related ligands by acting as an ActRIIB decoy, which also disrupts blood-vessel regulation — the reason it failed safety review.
- This page exists to document why people should not be self-injecting it, not how to.
What to monitor
The trial-stopping signals were nosebleeds, gum bleeding, and dilated blood vessels — not something to titrate around.
Legal & prescription status
No legal prescription exists. It is an unapproved research chemical, sold only for laboratory research and labelled 'not for human consumption.' It is not FDA-approved for any human use.
