a lot of orals can make you feel like shit... when your liver really disagrees or is not proceessing properly then that is a first indicator... headaches, lethargy, painful pumps etc... that's why i often go with half doses... you can't avoid toxicity, that's how they are made, although some have more than others... the two best preventative methods are using some sort of cycle support and testing doses and going a bit lower... not to mention when you get a rise in blood pressure, lipid and cholesterol issues, etc... it becomes very problematic and needs to be addressed... this is why sarms a such an excellent addition or even substitute... why get the nasty sides from dbol when you can use tbol stacked with lgd and get that kind of size without the estrogen, the harsher sides etc... or instead of running something weaker like anavar, run gw and s4 instead... its just a nice alternative to have... just keep in mind, when you run an oral, chances are you will experience so if not all of these sides....
