all good answers for you so far and i will echo what has already been said....in this game knowledge is power, but in the same breath dont listen to exactly what everyone says...as time goes and you read more and more you will figure out who is giving decent info and who is talking out of their ass...after you reasearch some more i also suggest a single ester supplement whatever that maybe that you feel you are ready for (test, winny,deca, or eq) and doing it that way you will find out how you react to that substance...you see when you stack things its hard to tell what is accomplishing what for you...as for your buddy that did the winny, well its all diet dependent, winny isnt really known as a "bulk" drug its used more so in cutting and thats why you havent noticed him getting "bigger".....read and ask questions......
