First off i have been researching deca and it sounds like it can actually heal torn ligaments and tendons and muscles. I am having some trouble with my shoulder and was curious if it would help ontop of add some velocity to me fastball. I was also curious if anyone knew which was better the deca 200 or 300? I might have to have surgury on my labrim in my shoulder so i also thought that if i did it could help me come back quicker. If anyone has answers to all my questions that would be great.
