Add your review


Myostatin, also known as Growth and Differentiation Factor-8 (GDF-8), is a negative regulator of muscle growth. Moreover, myostatin is expressed in various muscles in early developing humans and adults. Myostatin is considered a myokine. When skeletal muscle contracts it produces and releases cytokines along with other peptides called myokines. Furthermore, myostatin was first described as a myokine in 1977 by Se-Jin Lee, and along with being expressed in skeletal muscle is also expressed in cardiac muscle and fat tissue

Myostatin (GDF-8) inhibits muscle mass, and interruption of this gene has shown to result in a great deal of skeletal muscle growth. The main area in which myostatin is expressed is in skeletal muscle; inactivation of myostatin in this instance produces an increase in muscle mass in many animal species. Work using Myostatin knock-out mice – experiments where myostatin is rendered inactive – showed that these mice exhibited muscles around 2 to 3 times larger than mice which carried the normal Myostatin gene.


Doses of Myostatin propeptide have been tested mice and it has shown an optimal increase of muscle mass at a dose of 20mcg/kg It can be used every 5 days for 25 five days.

it seems like welts develop whenever these myo inhibitors are injected redness and soreness can be less when using sub q
