Description

ACE-031 (ACVR2B, Activin receptor type-2B)

ACE-031, also referred to as ACVR2B or ActRIIB-IgG1, is a synthetically produced protein that was originally developed by two bio-pharmaceutical companies, namely Acceleron and Shire, for its potential ability to inhibit myostatin and other naturally occurring proteins that limit muscle growth. It was hypothesized that ACE-031 would act as a decoy receptor for the catabolic proteins, specifically myostatin, and bind to them in an effort to keep them away from muscle fibers. Numerous studies have been conducted to determine if ACE-031 is an effective treatment for children who have Duchenne Muscular Dystrophy (DMD).

What is Myostatin?

Myostatin, abbreviated GDF-8 (Growth Differentiation Factor-8), is a protein naturally produced in mammals, which acts on muscle cells as an inhibitor of myogenesis (differentiation and growth of muscle cells). The gene encoding myostatin was discovered in 1997 by geneticists Se-Jin Lee and Alexandra McPherron who produced a strain of mutant mice that lack the gene. These scientists produced a strain of mice that lacked the gene and had approximately twice as much muscle as normal mice.

Ace-031, also known as ACVR2B, is a soluble form of activin type IIB receptor, which is an inhibitor of myostatin and other naturally occurring proteins that limit muscle growth.  This compound was genetically developed to bind to myostatin before it can attach to its receptor and halt muscle growth.  The two Biopharma companies that worked on this compound are Acceleron and Shire.

What is myostatin and why do bodybuilders want to stop it?

Myostatin is a hormone in our bodies that signals muscles to stop growing and replicating.  Therefore, when you inhibit, or block myostatin, muscles will be able to grow bigger and you will become stronger.  Imagine being able to block myostatin and continue to grow muscle indefinitely - you would be able to become like a super hero.

Negatives aspects and side effects

Even a slight decrease in myostatin would result in a dramatic increase in muscle mass, but it would also mean you would need more food to feed those muscles as well.  Another problem is that our heart would continue growing, since it is a muscle, and over time this could lead to heart failure due to having this organ work too hard.  Besides, in the long run, an unhealthy heart will definitely hurt your gains.  Furthermore, you could also argue that your stomach would grow as well because you can't control what muscles get affected or not.  For instance, certain muscles might grow bigger than others.  For example, you can have a 50% increase in your glutes and only 20% in your delts.

Human studies

In one human study, overweight females were given a one time dose of 250 milligrams (mg) of Ace 031.  As a result, after a month their muscles in the thighs grew over a pound.  What's more, their lean body mass increased 3%, which is quite a result.

However, in another study done on young boys with muscle dystrophy, the test subjects ended up having gum and nose bleeding.  Unfortunately, both Shire and Acceleron eventually abandoned their partnership, and since 2013 no further development has been conducted.  Since then, you can find Ace-031 being sold as research chemicals on various websites, but no trusted brand has come out selling it yet.

Other myostatins in production

MYO-029 was intended to be another myostatin blocker by Wyeth, but the results in their trial failed miserably, where subjects had zero strength gains.

Fat loss and bone health?

In the different studies that were conducted, subjects experienced a reduction in leptin concentration and boosted adiponectin, which is a 'good fat' hormone.  Hence, perhaps Ace-031 does really contribute to fat loss.  Another study showed an increase in alkaline phosphatase in the blood and reduced collagen telopeptide; this may mean it also helps strengthening the bones.

FSH effects?

In a study with females, the concentration of FSH (follicle-stimulating hormone) dropped significantly, and there is no explanation as to why.  Thus, it appears that there are some side effects, and we do not know if the same would occur in men.  However, we know that in cattle, farmers refuse to use Ace-031 to 'beef up' their stock because of infertility concerns.  Therefore, perhaps that connection has to do with mother nature not allowing an ultra muscular being to reproduce?

Dosage and Cost

During the studies done on Ace-031, where rats were injected, they were given 10mg/kg.  Hence, to match those types of figures, a normal sized adult bodybuilder would have to use about 1 gram a month, all things being equal.  This means that if you were to use a gram it would cost you tens of thousands of dollars to get in that amount each month.

According to bodybuilders who have been able to get Ace-031, dosages seem to range from 1-3mg per kg of body weight every 1-2 weeks. 

Half life

The half life of Ace-031 is 10-15 days.
