So neither would be that beneficial for mass gains? They would be more for aesthetic reasons correct? If that’s the case I’ll just pass on them.
Mast definatley, but primo will absolutley work for gaining muscle, you just need to take more of it than if you were to run nandrolone for example, but that also depends on where you are currently in terms of size and experience. 400 primo will do a lot for some, but i require 600+ with a gram of test to make a slight gain!
