I agree lots of people probably use doses/compounds that they don't need.

But is it possible for a bodybuilder/fitness model to go through their entire career doing test only cycles?

I have calculated I have enough test for just under 8 cycles at 500mg for 12 weeks, will there come a point where I'll have no option but to add deca or another compound? Or can I gain indefinitely?
