Most everything you said here is wrong...Do not do PCT while on cycle or while taking any exogenous hormones. Like mentioned in the post after yours PCT is for after the cycle has been completed and it is not to keep aromatization down it is used to help begin your natural production of testosterone again. On cycle, to control estrogen you should use an Aromatase Inhibitor like Aromasin or Arimidex.
The reasons you gave are also not good reasons necessarily to not take dbol. It stresses the liver, but not to the extent that it is sometimes played up to and there are measures that can be taken to minimize the stress. The liver is the second most resilient organ behind skin and it can and will repair itself if it isn't diseased. Aromatization can be easily controlled and the water retention does not unnecessarily strain the cardiovascular system.
Deca is not any easier on the body than dbol as it actually can present much harsher side effects. Every steroid can present some nasty side effects and it really depends on the person as every steroid can affect each of us in different ways. Please do some more research, because what you have said here shows that you've been reading mostly the wrong information.
milk thistle has been known for quite a while not to be a good choice for liver protection and it seems as of late that Liv-52 is falling in that same category...I've seen bloodwork from several people, including myself, that had elevated liver enzymes while taking Liv-52...my next cycle I'm gonna be using NAC and ALA...seen some studies on those of guys that had elevated enzymes and started using these two supplements and their values decreased dramatically
