I just finished my second week of my cycle which consists of

500mg test
400mg deca
30mg d-bol

But i just got some anadrol from a friend and was wondering if I can switch it with d-bol on my last 2 weeks since the oral is 4 weeks. Or should I hold off on it? If you guys say hold off, what should I stack it with? Can it be taken alone for my next cycle? Need ASAP. Thanks bros.
