I would say that 40mg of anavar is a good dose if it is properly dosed.
I may run 20-30mg a day alongside 200-250 test soon. Tbh i dont expect a lot from Var at that dose, some hardening and freeing up of test i guess. But the only other thing i have that i could add to test is tren ace, and i dont want to run that now.
It is more about the synergy of test, var and mk677 for me. In theory that stack should be more anabolic than just throwing in 500mg of test.
Btw what dose of test are you running? 200mg a week?
