I think it all depends on what your goals are. I think its a good way to experiment with the effects of the drug, I used eq alone and it was good but the results were not too noticable, I also used anavar by itself at a very low dose, the results were the same, each drug was good at maintaining mass and neither had a crash when done using. If it is mass your looking for it's good for you to stack at least two drugs like eq and testosterone etc. Thats just speaking from my experience.
