Dont waste your money or time i know from personal experience also the only trials in mice that worked with any if them they infused them into some kind of vaccination i believe

It's bunk. You're chasing a unicorn. I have a masters degree in exercise physiology, and I have read the research. Myostatin inhibition is a result of genetic anomalies or variations that cannot be reproduced by even the biggest pharmaceutical companies. If this mystical unicorn ever is "invented", it will be made by big pharma, and not legal for sale by supplement companies... it's potentially very dangerous, and if it is developed it will likely be used for increasing meat production in livestock, with little to no possibility of use in humans.
