It's ok to use fat burners alongside d-bol, but I would advise against ephedrine, It could be more than your liver at stake. Check this out : http://www.ephedrine-ephedra.com/
I would reccomend Clenbuterol. This is much safer and is available from most anabolics suppliers.
That's like saying "Ummm no you shouldn't be juicing in the first place. Come on people. You speak too general. Anyway clen better and safer than ephedrine? I think not.
D-bol and ephedrine is a good mix if trying to build mass and keep fat retension low if dieting or if in mass building phase. Now if you're extremely overweight and eat a horrible diet and do 0 cardio and do tons of d-bol and alot of ephedrine I would advise against it. After having said that half the people on here still do it like that except they stack other high androgens in the mix as well.
