Mast E makes me shed like crazy by week 4, but I get a lot dryer and harder than with mast prop. I also get way hornier. I didn't notice any strength gains with mast e, but I bailed pretty quickly because by week 6 I just couldn't stand to watch my hair fall out anymore. Life stressors may have been contributing to this at the time, but I know for a fact I lost a lot more water with Mast E. Considerably more. I was amazed.
Mast P = dry, hard, horny, mild strength
Mast E = as dry (lost 7 lbs of water rather than 4), harder, hornier, no strength, hair loss.
