alright bros ,when taking roids we deliver da message to our receptor site to build muscle wich then our receptors deliver it to our muscles cells to build more muscle.when we work out we stimulate da muscle which ever one it is example biceps.we then grow bigger by tearing da muscles and then resting to let them recuperate bigger .how does all this come in to play.if were delivering a message all da time with roids why arent we growing all da time .im guessing when we stimulate da muscle were also sending another message to da musle cell to grow da muscle we just stimulate . hope this makes sense any opinions
