That’s what I did, 400/400 Test/Primo, slow steady gains for the win.I didn’t start running Primo until I got older, and have always ran it at 400 and just doubled my TRT dose, usually for 12 weeks, but I have gone 16 weeks because I loved the slow steady gains.
To be honest that 16 week run was really nice and made me want more, but I had to show restraint.
I don’t do anything too harsh anymore, just enough to be able to enjoy a cycle or two a year and then back to TRT.
