I myself have only done 2 Test only cycles, i'm wanting badly to try out Primo / Test for next run. Why do people always talk about when running the two together they lower the test to about 200-300mg per week while running Primo at about 600mg or so. Why can't you run the Test also at the standard 400-500mg? Is it just too much compound for people to put in their body? or just running Primo you just don't need as much Test for good gains? Please if some people who have experience please shed some light, THanks!
