If this is your first cycle of anything, start with 10mgs. of var. first week, second wk. 15mgs. see how your body is responding, then 20mgs. 3rd.wk. 25-30 mgs. My first cycle of var. I found that anything over 25mgs. did nothing more than waste my money. Again, this is basic on a first cycle only. If you have use before to any extent, think about your receptors, than this would not apply. Each person is different in their response to any roid.
