Total BS. Ronnie used 36IU HGH per day and diminishing returns usually don't happen until 40IU's per day. And pro bb'ers use well over 100IU's of insulin daily these days, some up to 200IU's. Long-acting slin in the morning, 15-25IU's before each meal, 20-30IU's pre-workout and post-workout. Most of the good ones never eat without slin, as they feel it's pointless to do otherwise.
Don't forget the vast quantities of research peptides. Little research has been done on them, but pro bb'ers are drug addicts and are scared that others might be doing these things and gaining benefit from them. Gear use is 5g-10g per week typically. Orals in the 100-500mg range daily. Some get off orals occasionally, some don't. You should for liver health, but bb'ing has never been about health and never will be.
Also, rec drugs like narcotics, weed, and amphetamines are common to tolerate the abuse on the body. A lot of the bullshit cycles you see like this one might get you up to a relatively lean 220-230 assuming average height and good genetics, but you need to really pound down the doses if you ever expect to competing at 250+.
In the end, it's all genetics anyway. Many guys get tons of sides on 1g gear per week with nothing else added. Those guys simply aren't met for pro bb'ing. Most pros use 6g+ per week. 6g shouldn't be necessary but considering that most of these guys never come off, their receptors are always saturated and only get further growth by continually pounding down higher doses over the course of 10-20 years.
