Well, of course you know everyone reacts differently. I'll give you my experience. Doses in the 400mg range did nearly nothing for me. Now, 800mg, you're talking an awesome dose. Part 2 would be the length of the cycle. Primo really shows it's true colors and shines (again, for me) around week 14. I see changes in the mirror almost daily at that point. So I typically never run it less than 16 to 18 weeks @ 800mg +.
That being said, I probably would stay on the lower end of a good dose for a first cycle. 600mg is just fine, but I would certainly take it longer than 12 weeks.
As for running it on a TRT dose, I've never done that so I won't be able to provide any info. Blood work on primo showed Estrodial always just under 30. Test was always elevated because of my test dose. Always used adex @ .5 EOD . Rarely do I have to go to ED.
If I recall, you are trying to get to 6% ? Not sure where you are now, but for me, I need to be fairly lean to get the most out of it.
No sense talking to you about diet, I always refer to you in that department
