Building muscles is beneficial for both your physical and mental well-being. Increased muscle mass enhances your strength and functional abilities, making everyday tasks easier and reducing the risk of injuries. Additionally, building muscles contributes to a higher metabolism, aiding in weight management and overall health. Strong muscles provide crucial support to joints and bones, positively affecting mental health, improving mood, reducing stress, and boosting confidence. This article will cover a drug called ACE-031 peptide that can increase skeletal muscle mass and improve metabolism, joint support, and thus a holistic overall health and quality of life.




Ace-031, often called ACVR2B, is a soluble version of the activin type IIB receptor, which inhibits muscle growth by inhibiting myostatin and other naturally occurring proteins. This substance was created genetically such that it would bind to myostatin before the protein could bind to its receptor and stop muscle growth. Acceleron and Shire were the two Biopharma companies that collaborated to create this remarkable molecule.

ACE-031 Peptide – Product Information

ACE 031 as a peptide is a strong myostatin inhibitor that has a high affinity to bind to myostatin (GDF-8), thus preventing myostatin from binding and activating its natural ACVR2B receptor that is responsible for the suppression of muscle growth (preventing myostatin from delivering the muscle growth-limiting signal).

In clinical trials, myostatin is reported to bind to ACE 031, a soluble version of the activin type IIB receptor, and inhibit its actions. Muscle cells produce a protein called myostatin that prevents skeletal muscle growth and hyperplasia. Additionally, ACE 031 likely impacts sperm health, fat storage, and bone metabolism.

In this way, ACE 031, as a drug, has the potential to significantly help in the development and maintenance of muscles and maximal skeletal muscle hypertrophy. Due to this property and ability, ACE 031 research shows great promise for patients with a symptom of neuromuscular disease. [R]

ACE-031 Mechanism of Action

ACE-031 operates by inhibiting myostatin, a naturally occurring protein in the body that plays a crucial role in regulating muscle growth. The myostatin gene affects muscularity negatively, limiting how much muscle an individual can develop. By inhibiting myostatin, ACE-031 is designed to release this brake on muscle growth, potentially leading to increased muscle mass and strength.

The mechanism of action of ACE-031 can be summarized as follows:

Binding to Myostatin: ACE-031 is designed to bind to myostatin, preventing it from interacting with its natural receptors on muscle cells. {R}

Inhibition of Myostatin Signaling: When myostatin binds to its receptors, it initiates a myostatin signaling pathway cascade that ultimately inhibits the growth and differentiation of muscle cells. ACE-031 is intended to block the inhibitory effects of myostatin by preventing this interaction. {R}

Promotion of Muscle Growth: With myostatin inhibited, the normal regulatory constraints on muscle growth are reduced, potentially allowing for increased muscle mass and strength. {R}

ACE-031 Benefits

Among its numerous benefits, here are a few that ACE-031 is most popular for:

1. Muscle Growth:

By inhibiting myostatin, ACE-031 is believed to enhance muscle growth and development. In recent studies, the muscle weight, specifically the thigh muscle volume, increased significantly with the use of the drug. {R}

2. Muscle Strength:

Increased muscle mass could lead to improved muscle strength. By preserving the energy supply and altering the muscle’s thermodynamics to favor oxidative respiration, ACE 031 can improve the muscle tissue’s capacity to produce force. {R}

3. Muscle Protection in Women:

ACE 031 has been proven effective in maintaining muscle mass in postmenopausal, healthy women. To maintain long-term bone health, maintaining muscle in such a way is essential for overall well-being. Thus it promotes muscle growth (growth hormone, IGF-1) and decreases muscle wasting.{R}

4. Energy Metabolism:

Myostatin may have a detrimental impact on the energy metabolism of muscles. By blocking myostatin, ACE 031 promotes muscular growth while increasing the muscles’ oxidative potential, protecting against fatigue and the negative effects of free radical generation. {R}

5. Muscle Repair in Muscular Dystrophy:

In “Duchenne muscular dystrophy disease,” muscle cells are fragile and prone to injury because of a dystrophin protein that isn’t functioning optimally. Myostatin seeps from injured muscle cells and slows or inhibits the growth of other cells as a secondary impact. ACE 031 reduces muscle deterioration by lowering the secondary impact of myostatin and addresses the dystrophin dysfunction. {R}

6. Bone Density Enhancement:

Additionally, the peptide has a trend towards greater bone mineral density, decreased fat mass, and increased lean body mass. {R}

7. Protection Against Chemotherapy Induced Muscle Atrophy:

Other elements than strength, lean body mass, and muscular composition affect ACE 031’s anti-cancer properties. Preventing muscle loss during cancer treatment and in the presence of cancer significantly extends the lifetime. In cancer patients, myostatin inactivation improves insulin sensitivity, lowers lipodystrophy (a build-up of fat), lowers inflammation, and speeds up the healing of fractures by strengthening bones. {R}

Moreover, ACE-031 has been explored for its potential therapeutic applications in conditions characterized by muscle-wasting diseases, such as limb-girdle muscular dystrophy, chronic obstructive pulmonary disease, and sporadic inclusion body myositis. Research has focused on its ability to increase muscle mass and strength.

Side Effects

Though adverse events associated with ACE-031 are minimal, some potential but rare side effects associated with ACE-031 might include:

Hypertrophy of Heart:

There is a possibility of cardiac hypertrophy (enlargement of the heart), which could pose risks to cardiovascular health.

Joint and Bone Issues:

Since myostatin also regulates bone density and joint health, some concerns inhibiting myostatin with ACE-031 might have unintended effects on these systems.

Is it Legal?

In August 2010, the US Food and Medicine Administration (FDA) designated the medication as an orphan medicine for treating Duchenne Muscular Dystrophy (DMD).


The recommended dosages range from 1-3mg per kg of body weight every 1-2 weeks.
