I take 300mg max of deca and I love it. Higher doses shut you down. [/B][/QUOTE] true that,when your "shut down" your shut down,i see no in betweens.thats why i am doing 800 mg deca,320mg fina a week,along with 1000mg sust. imho if your going to take enough to close that door,then that doors shut,so other than the usual sides what more harm can be done?
