If you are running a minimum of 2 cycles a year, planning to keep going .. potentially forever (*), do you need to confuse the body on compounds?
To give an extreme example, if you run 6 test c / deca cycles in a row, wouldn't the gains taper off?
But if you are always changing the compounds, and doing things like short esters in one then long esters the others, you will see better results?
Is there any research available on this including personal testimonies or even hunches etc ?
