I was on 40mg of DV2 and again on DV1 no problems. I actually prefer it at that mg minus some slight headaches and minor sides but my body reacted well. To be honest man it really just depends on your body.. you want to use the least amount of gear as poss to reach your goals... CK ran 50mg of beast somthing I dont htink many people have or want to do , but for him it was gold..
