I know i may sound a little ignorant at the moment but i did my fair share of research about deca. maybe my sources were not good enough and that is why i posted the question on this forum.
Just to give you some background info about myself, I am a mountain guide and last december i had surgery on my shoulder and during my recovery time i lost a lot of muscle tone and mass. so far ive been training at the gym and havent seen much progress. i have to guide a trip on april and i need to be good by then so the deca is to speed things up so to speak. please if im doing anything wrong (and i know i might) tell me how to fix it. last monday i had my first shot and this friday im supposed to have my second.
