dianabol is the name that makes you feel like you might turn into Arnold, I don't think there is a person that didn't have the wildest fantasies for the compound. You do get some radical changes, your weight absolutely sky rockets, but very little to nothing is of quality muscle as muscle doesn't build in a few days.
So as Empire pointed out, there is other drugs that work more elegantly. But it you hell bent on putting an exhaust on a city golf and making yourself think you a v6 by all meals go ahead. Dianabol is so toxic, side effects are high, you risk crashing out and losing the little you may have gained, but it will be just that, a little, you will also visibly look like you grew extremely quick from the water and then everyone will ask you what happened and why you looking so small of a sudden.
