lost 4 lbs in 5 days at 200mg, didnt feel all that bad either, just a little warm. Ive used it before and will again after next cycle. Is it dangerous? Hell ya, if your a moron and dont use common sense. So for those those that dont have the time to round up supplies, test dosage and generally just plain be carefull, dont even think about it. Cause personally I am tired of people getting themselves hurt and ruining things for those that do thier homework.
