I think the major thing to concern yourself with at any stage of the game is not necessarily the weekly dose but how the amounts can accumulate due to the esters and the frequency of use. Gear like sustanon or any of the T-500 types can really build into mega levels without you being aware since the longer esters are still operating while you keep pumping more in. Personally, I have very much liked levels that max out around the 1000mg of test weekly (and stay stable), but I also run somewhat shorter cycles and don't really do that anymore. I've made homebrew for years and have had great daily pin cycles around the 1000mg per week mark that leave me really lean and hard but get out quickly due to the very short ester. One of the big experience points in AAS use is stable hormone levels and knowing the right dosages and cycle lengths for your goals.
