Lots of heavy compound movements when on, also high volume. Especially when on GH. My joints and tendons can take the beating. Only once or twice a year do I "take it easy" and do high rep, light weight work for a few weeks at a time. Even during PCT/bridging I lift heavy, but the volume is much less. For a large bp like back while on I'll do at least 20 sets (by "on" I mean at least 2 grams of gear and GH/IGF-1), when off I'll do 3 sets of barbell rows, 3 sets T-bar, 3 sets dumbell rows, and 3 sets pulldowns. All heavy, but the actual time in the gym is much less and overall training volume is less. Also, when off, I don't lift more than 4 times a week. When on, 6 days a week.
