What is ACE-031?
ActRIIB decoy receptor that inhibits myostatin; experimental muscle-growth compound.
How ACE-031 works
A soluble ActRIIB receptor that traps myostatin AND activin, removing the brakes on muscle growth — powerful but non-selective.
Benefits & uses
- Dramatic muscle mass increase (myostatin inhibition)
- Studied for muscular dystrophy
- Strength interest
Common uses: Muscle growth / muscular disorders (experimental).
ACE-031 dosage
- Typical dose
- Experimental myostatin/ActRIIB inhibitor; dosed conservatively in research, roughly weekly. Limited human data.

long
ACE-031 side effects
- 🔴 Nosebleeds and gum/vascular bleeding (dilated blood vessels)
- Skin capillary changes
- Vascular side effects
Warnings & monitoring
- 🔴 CLINICAL TRIALS WERE HALTED due to safety concerns — bleeding/vascular effects (dilated blood vessels, nosebleeds). This is the defining safety fact. Experimental research chemical — serious risk signal.
Preparation & storage
