If runs D-bol do it for at least 4-6 weeks this is a safe period of time for the liver, also if your not an experience user use one oral at the time.
Reason for this is so you will learn how your body reacts to diffrent compounds so you know what to expect for each compound you use, when mix or use after the other can be very toxic for your liver plus sides can be more complicated.
If I am you will do the D-bol 30-50mgs ed for 4-6 weeks or the same for T-bol but one after the other.
You will be using Test right?????
