I like the primo dose and the longer you run it the better. He is kind of in a bind with the sust since he only has amps so he will need to pop a ml at a time. I wouldn't mind running higher test in the beginning say an amp MWF or even eod depending on prior cycles and then switching over to test e or c at the last half of the cycle and running more of a maintenance dose to let the effects of the primo show through without potentially being covered up from excess water from the higher test. (I actually like the idea of using test P with the primo since you basically need to be pinning eod or ED to reduce the amount of oil per shot). Now if you are looking to do this as a strictly mass building cycle then just keep the test higher all through the cycle and slam the protein.
