I would say minimum dosage of primobolan would be 400ew in 8weeks, 10weeks would be perfect
What ever is going to increase you in size, speed, endurence, ect ect. will be more powerfull then your own hormon producktion.
if you body makes 70g of test a week, shoting 400g of test is way more then your body, it will shutdown its own produciton to try regulate the amount of test. though it can only get rid of 70g.
So yes, every roids will go and shut you down to some degree and yes PCT will be required.
Imo yield from the very bottem, do one cycle primobolan, then anavar. then combine primbolan and var.
then test - var.. test - var - deca ect.
I am not a big fan of needles/pins.. ive tried to shot my self with primobolan and found it quite hard! i hated it.
so im so far sticking on win and anavar cycles still one day if so ill do pinning.
