I think you need to do more research about AAS and the drugs associated with them before you start injecting yourself....
This being your 1st cycle and it being a base TEST cycle, a normal Nolva/Clomid 4 week PCT should be sufficient...

AI are cheap and worth the peace of mind, b/c if some gyno flares up...
Given the word "ideal" in teh question... It's obvious the lower the better whether bulking or cutting imo...
But what the bros have said he is accurate...
