i stayed on primo dept pretty much all last summer. At 400mgs per week i took it for 12 weeks and gained a decent amt of lean mass while keeping my bodyfat low with no loss of strength. 400mgs is pretty much the lowest u can take if u want to see some results. i am gonna run it at 800mgs this summer for 8 to 12 weeks on a cut cycle with anavar, fina , winny, and halotestin.
coming of a anadrol/sust/eq stack right now and getting ready to start using it for gainskeeping with some clomid.
you know on-off, mostly on.
Doing 600 mgr/week gave no boost over doing 400 mgr/week.
So stick to the 400 mgr and add the Ox. Now this will give you a boost.
