Depends what purpose your taking it for.its not just a pre comp drug,you can use it in your cycle when you want to increase your rep max(great for POWERLIFTERS)which obviously for the modern day bodybuilder that means over the recommended time span of 4-6 weeks you can put some serious size on,and as a pre comp drug/or leaning up for your summer look,this will give you that extra hardness and volumization under restricted calories so you look fuller instead of being stringy.we all know when were restricting calories in the summer our strength just goes(well mine does anyway)this will offset that and some!!
