with everything but anavar.....i think it is the MG amount that is the problem. don't go too high on total MG's of orals. you can take 5 different orals....but keep it under 100mg's and its the same as taking 100mg of dbol alone. ya know? of course dbol/anadrol have the worst side effects though. i don't see how they are harder on the liver than say winny. but it may be so. anavar i have seen actually help with liver values, so i doubt it would cause any problems. but you never know.
