I'm not sure why the effects would have to exceed DHT from test? Could you elaborate a bit more on that?
I was thinking of something along the lines of between 200-400mg test per week, a gram of deca, and either finasteride or dutasteride in a reasonable dose. Low dose AI for the test and reasonable dose of proviron to allow for the fact you have no DHT. Throw in some dbol and I bet that you'd have an interesting cycle. If you used NPP you could probably run a 4-6 week tester, you'd have to make sure you had stable blood levels of the 5AR inhibitor before starting, and drop it before PCT.
I'd run it myself, but I'm running test eq and primo at the moment and will be coming off in a few weeks so its not exactly the best time for me.
