It wouldn't matter what Arnold's steroid cycles were - it would have zero bearing on how anyone else would respond to it.
Nobody but Arnold had his bone structure, tendon, ligament, and muscle shape and insertion points, muscle fiber density and fast/slow twitch composition, his digestive and elimination system, nervous system, and mental disposition/willpower.
The best thing is to figure out what works for you - not someone else. People can share their experiences, but despite all being human, each of us is a different building, with different materials and quality built into our foundation, framing, and overall package.
Arnold had the best of everything for the most part, because even his weak points actually contributed to his unique look - such as his abs.
