ACE 031 

Each VIAL contains 1mg

ACE 031 is a Myostatin inhibitor. Myostatin slows and reduces muscle growth. It has been proved that Ace 031 promotes faster, more robust and better growth of new muscle mass. The use of ACE 031 unlocks the protein's restriction on muscles providing them with unrestricted potential to grow bigger. 

Research has shown that the lack of Myostatin on test subjects had Twice as much muscle as those that had normal levels of Myostatin in their system.

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 fibres.


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.

When used on human test subjects it was found that ACE-031 showed substantial (in excess of 10%) muscle growth and increased strength in all test subjects when compared to those who had been administered with placebo products. Tests involving skeletal muscle building,  a single dose of ACE-031 was administered to test subjects. Results recorded over 2 pounds of muscle was developed by each test subject over a short period of two weeks. No serious adverse effects were seen.

The Half Life is approx. 12 days
