TweetYea man, i've runa var only cycle and loved it. it's not for mass gaining -but will definately change body composition. 25-30 mg's may be a little low to run by itself if it is a generic or UG preparation. You would want to go 40-50. And eight weeks should be ok if you take care of yourself. You could take Tyler's liver detox as a good all around liver protector. Also include l-glutathion(sp?). when peole go to the hospital after a parasuicide atempt by taking a handfull of tylanol or something -they are given a shot of this to protect their liver. Also make shure you take plenty of omega-3's and omega-6's to protect your HDL/LDL heart levels and of course drink plenty of water. you may want to go get your liver values checked around week 4-5 just to make shure everything is ok. Var only is great for athletic improvement- good luck
