This. When I lived in Missouri I'd see Chad around here and there and he told me that the biggest difference w/ Coleman wasn't so much the GH it was keeping him consistent the entire prep. I remember Chad sort of groaning about how he needs to call Coleman up to 10 times a day to make sure he was on track because Coleman would just sort of "not feel like training" for a week or he wouldn't do any cardio or even remotely stay on a diet. Chad had to tell him to "TRY" to eat as clean as he could throughout the day because he knew Coleman would never follow any prescribed diet.
Also when Coleman was at his best he was keeping his relatives and family a little more distant because Chad said they'd milk him for money and resource all the time. So it wasnt so much drugs it was more keeping him motivated and in the gym. GH and tren were Colemans staples. He wasnt very disciplined he wouldnt take his injections or literally he would forget about him Chad almost hated dealing with him. His superior genetics carried him a long way but Coleman was a child who needed babysitting.
I don't know about this but I saw Ronnie around a lot during 2003-2005 and he looked pretty disciplined to me, don't know much behind what u said
