I have done and Mdrol Hdrol run twice in the past. Its been about 2 years since I last used any PH/PS's but it was a strong combo at the time. Once I started the run with Mdrol for the first 2 weeks, bridged weeks 3-4, then went High dose H-drol the last two, I reversed the order the second time around. Worked better finishing with the Hdrol IMO. Make sure your "buddy" has his ducks in a row; this is a very very toxic combo, and will shut you down pretty hard as well. Maintain a diet high in good carbs all the way through to fight lethargy as well.
