U take 50mg+ u have a extremely high chance of shutting down. 30mgs won't do sh*t. 60mg+ at least. Its HARD to find legit Var. I have tested 6 different brands now and only 2 have been legit.. Op masteron is much better. I run 1gram of it with zero side. (I'm not saying to run that high just giving an example) 700mg is a great range for masteron e . Yes its good to be a low bf% but it still puts on slow solid muscle IMO.better bang for ur buck. Less chance to be faked too.
