As a tall fatty at 6' 6" and 332lbs, I would say stay away from it for now.
I ran 250mg Cyp/Enan (which ever one I could get) every week for a year and then blasted 15 weeks at 500mg per week. I gained very little strength and size and lost some weight. I would run a cycle at 500mg and (myself) being "fat", I would recommend an AI. I use amiridex at .25X2 a week at 250mg and .5X2 a week at 500mg.
No girlie boobs yet and my manboob (moobs?) are slowly disappearing. I straightened up my diet (big time last week - hopefully more fat loss) and train weights 4 times a week and cardio around 4-5 hours a week.
Note that I gave myself, wish I had read more or was told:
You can go into a slight calorie deficit (go for 1-2lbs weight lose per week) and maintain your muscle strength/size with the help of testosterone (500mg of cyp/enan for myself). Just make sure your diet is "clean" and you are hitting the weights.
They say you need a surplus of calories to make #GAINZ... well, my gain is fat lose. I'm okay with maintaining strength/size right now, I don't care (yet) to grow. Once I get to 15-20% BF (about 33-34 now), I'll then start eating to grow with help from gear.
Good luck and keep us posted.
