I would say if u are getting legit primo, 500mg a week is a great dose... Over 90% of primos tested come back as either deca, eq, or test prop... Def. test it if u can... If u are worried about bloat this could play a factor, as both eq and deca will cause retention....
Mast anywhere between 400-600 should suffice... It will rip u up and give u a grainy look...
