You are pretty much right. The "hard" look comes from low bodyfat and little water retention. Stacking drugs like Winstrol or Primo work great when you take test along with arimidex to combat the estrogen, which is the main cause of excess water. Adding in a diuretic also helps you attain paper thin skin. Dont go for Lasix though, it works but is too dangerous. Go for something like taraxatone to get off the last bit of water. And of course, the most important aspect is to eat a clean diet and do cardio a few times a week.
I've got a friend who ran this "cycle":
YEARS 1-3: deca, winstrol, laurabolan, Primobolan - continuous
suspension, halo, anadrol - cycled
liquid clen, 4-8 thermadrenes/day
I promise I am not exagerating. He looked absolutely phenomenal. Spiderwebs in his abs and calves. He could pull a vein across his calf, flex it and it would pop back into place.
He ended up at 5'11 220lbs 4%bf
He ended up having a panic attack after taking a sip of liquid clen, had to go to the hospital, and had to go off everything cold turkey. no clomid, nothing. He was extremely depressed for about 3 months. That was about 3 years ago. Now he is natural at 200 lbs with about 10% bf. Not bad, but not what he once was.
His words of wisdom: "its all an illusion"
I learned numerous valuable lessons from his rise and fall.
