On 200/70 you were still feeling shit with 45 e2 or better? You're just one of the many guys that need to run test higher and honestly if you're not having sides from pushing test higher i don't see why it would be a bad idea of taking 750 test and 400 primo for example instead of taking 500 test and 700 masteron.
As far as i can understand people search for a second anabolic when they hit the ceiling with test and the side effects don't worth to push it higher. For us gymbros and low level competitive bbers who still trying to put some good mass on perhaps pushing test higher is a better choice.
I'm no expert at all dude, just saying my opinion..but when i see guys that wanna run 200 test and push mast or primo or dhb to a gram i cringe a little and i'm talking about gymbros and average users chasing size and muscle mass because if you're ifbb pro you already have the mass and you need more of the cosmetic drugs to fine tune your physique. This is what i'm understanding so far from my research, maybe i'm wrong..
