i've tried androspray and i like it a lot...i haven't tried 4 -aderm, but i plan to try it based on what i've read here and on par's website...i've been pleasantly surprised by androspray in that i've added 7 pounds and maintained or increased my strength in the six weeks since i completed a cycle of test and eq...very impressive...i've also made sure to keep my calories and protein high and have added dessicated liver and amino acid tabs with each meal...sort of an old school/new school combination...
