naa bro , pyramiding isn't really used nowadays , it is already proved that you will not START to produce EVEN ONE SINGLE ML of test UNTILL you stop introducing it . So there really is no point .
It is even worse , if you are taking 500 mg test a week ....and making good gains out of it , and if you start using 300 mg for 2 weeks , then 150 mg for 2 weeks and so on , and then , later stop it . You have just WASTED your GEAR because you will stop growing and at the same time NOT allowing your body to start producing it . So , there is really no point in this .
All that cortisol thing and muscle loss can easily be avoided with the right PCT + suplements + diet manipulation .
