you gotta clarify whether it is the inj masterone or that "oral masteron" stuff. I've used both and they are very differents drugs.
the inj is great for hardness...the oral isn't...it actually seems better as a bulking drug. If you want an oral for hardness winstrol or anavar are much better then the oral masteron.
both "masterons" provide a good kick to training aggression. both will also probably make you lose alot of hair if you are prone to it.
