Unfortunately, doping has gotten better in the last two decades. Where as before simple AAS would be taken (and popped like candy) newer technology has set the the Coleman era apart. In particular, IGF-1 is the biggest culprit for the gigantism (Barry Bond-esque head, Coleman's distended belly etc) prevalent among professional bodybuilders.
This man would have been considered a giant among men fifty years ago. Now he is simply average.
Now as for you sir, thank you for pointing out that Winstrol is the same as AAS. Unfortunately, though they are both steroids. The AAS that the bodybuilders of yonderyear took in no way resembles Winstrol. Winstrol is both stronger and taken in far larger doses than the originalk, prevalent testosterone drug.
Now, off my soap box. As anyone who thinks that guy is natural...he be takin' dat dere cell tech.
