ACE-031 Research Overview, Uses and Key Information
Researchers designed ACE-031 to inhibit myostatin, a natural regulator that limits muscle growth.
A collaboration between Acceleron Pharma and Shire Pharmaceuticals created ACE-031, and researchers studied it as a potential treatment for DMD.
How ACE-031 Works
ACE-031 is created by fusing a soluble activin type IIB receptor (ActRIIB) to part of a human immunoglobulin (IgG1).
It functions by binding to myostatin and related ligands, preventing them from interacting with their natural receptors on muscle cells.
By blocking these signals, ACE-031 promotes muscle growth and strength.
Potential Benefits
Researchers have investigated ACE-031 for several potential benefits, even though it has not been approved for medical use.
Increased muscle mass
By inhibiting myostatin, ACE-031 may promote lean muscle growth, especially in individuals with muscle-wasting conditions.
Improved strength and endurance
Clinical trials showed increases in muscle volume and grip strength in some participants.
Therapeutic use for muscle-related diseases
It was studied primarily for conditions like Duchenne Muscular Dystrophy (DMD) and sarcopenia (age-related muscle loss).
Possible use in metabolic health
Some studies suggested potential benefits in regulating fat mass and improving metabolic profiles.
Research and Clinical Trials
In early-stage clinical trials, ACE-031 showed promising results in increasing lean body mass and muscle strength in patients with DMD.
The company discontinued clinical development in 2011 due to safety concerns and unexpected side effects, including minor bleeding and vascular abnormalities.
Nevertheless, researchers continue to study myostatin inhibition, investigating newer compounds.
Risks and Side Effects
Although ACE-031 has not been approved or widely available for therapeutic use, researchers reported side effects during clinical studies.
Nosebleeds
Gum bleeding
Telangiectasia (small dilated blood vessels)
Vascular issues
Nevertheless, unknown long-term effects.
However, these issues led to the suspension of its development.
ACE-031 in Bodybuilding (Off-Label Use)
Due to its muscle-building potential, ACE-031 has attracted attention in the bodybuilding and performance-enhancing communities. However:
However, it is not legal for human consumption or sale as a supplement.
Furthermore, regulators do not regulate the use, and people question the quality control of underground sources.
Health risks are significant, particularly with improper dosing or prolonged use.
