If this is you first try i'd recommend running m-drol solo for 3-4 weeks (10/20/20 or 10/10/20/20), m-drol is strong enough by itself that it does not need to be stacked, I was running it at 10mg for 2 weeks and had great pumps all day long, remember that m-drol is very strong staking it should be done by advanced users. good luck
