A 100mg shot of Deca will shut down your HPTA for 2-3 weeks before it returns to baseline. Tren is 5x more suppressive than Deca. This is why it is not advised to run Deca and Tren in the same cycle. Recovery is extremly difficult, thus meaning it will be harder to attain any gains made whilst "on".
Also Deca and Tren are Progestin's. You must also run an Anti-Progesterone to combat their side effects.
Pick one or the other IMHO, not both. For mass Deca. Tren is only advised for the more experienced user's aswell.
