Mj does not lower the strength of juice however since it makes you feel tired you can not give 100% at the gym and thats a waste in my book. If you take juice you better hit the gym harder otherwise whats the point of taking them.
I did cycles including deca,test, equipoise and anapolon but are you gonna take them all in one cycle or you gonna bulk up first w deca/test and anapolon and cut with test propionate and equipoise?
I am on GH right now and you know you gotta lower you blood sugar by taking insulin, guess what MJ does it for you. So if one day you get on GH you dont need to stick slin as long as you are cycling mj with GH.
also during contest preperation contestants smoke a lot of weed to deepen their cuts, the key is drinking lots of water instead of going carazy for munchies. If you can hold your self after mj you get sick definition, sliced and diced. I did it before, I did a diet with mj and my bf dropped down to 3% while maintaning lots of muscle.
So mj is good and bad for bodybuilding. it is bad cause you need more oxygen in your lung, it is good cause you can eat a lot with mj and bulk up in winter and you can diet with it and get lean faster.
One quick note, to prevent deca dick you must take equal or more amount of test to supress deca, otherwise your dick will go on vacation for some time.
