out of all the DHT based drugs, i found that nothing dries me out more than winny. its a great compound for the tail end of a cutting phase. the quality of the muscle becomes very hard and dense looking and vascularity becomes quite pronounced. its a perfect 'icing on the cake'. that being said, it is also very harsh on your body. dry connective tissues can lead to injury in the gym, not to mention, over time, you feel the dryness in your joints. it can be sharp and painful. it can be frustrating when you feel very strong from the winny but it is also limiting you ability to preform in the gym, due to pain. also, my blood work has proven to me that its one of the worst on your cholesterol. after running it for several wks, my good cholesterol had gone down to 0!!! not good. of course that will return to normal over time, but repeatedly doing this just isnt going to be good. 

i say all of this to back up my suggestion of keeping it at 50mg. you could get results with less, but 50 is a good strong dose and you'll see your body respond fast. its when i've gone higher than that, or when i've extended my winny use past 6 wks, that i've noticed joint problems. winny has about a 9-10 hr half life, so split your dose into 2x a day and you'll start seeing and feeling results in the 2nd wk.

also, if getting dry and hard is your goal, be sure to have enough AI on hand to keep estrogen low. when cutting, i will use much more than when bulking. i'd start at a moderate .5mg EOD adex but as the diet draws closer to the end, i would up it from there to ED, if you are still holding fluid. look in your lower back and glutes. those are usually the last places to go on many people.
