If more people would have experimented with lower doses before they got into the very high dose territory, they probably could have also made similar gains like this. Most people just listen to others when it comes to planning their cycle out and establishing their dose. They don't experiment with small doses first, usually because they're so anxious to get big quickly and they just don't make good decisions. I could do the above cycle and have those results also, because I only do very small doses and don't allow my body to get accustomed to the higher dose cycles that seem to be the norm of most people. Why? I don't know, I guess most people just think that more is better and this is what made steroids dangerous and brought about so many side-effects which could have been easily avoided.

PS - The bodybuilders of the 70's favorite stacks included this D-Bol/Primo stack, in fact this was Arnold's favorite and it's been said that their doses were considerably less than the doses of today. IMO, they looked much better back then than bodybuilders look today. The GH and all that other bullshit of today wasn't used back then.
