ok here's the deal.... REAL superdrol is methyldrostanolone. It is chemically similar to masteron and proviron, yet acts like neither. This is similar to how Dbol is simply EQ with a C-17 alkylation. Those 2 don't act alike either. 40-50mg is a VERY high dose for real superdrol, while 20mg is pretty standard. Most men have bad side effects while using superdrol, however the in the cases I've seen, all users were taking over 20mg ED. Liver toxicity and headaches are of particular concern for most, but in women the dose is about 1/8th of what a man would normally use so those side effects should not be an issue.
It would seem to me that the only reason a woman would want to use SD is if it's the legal "clone" version and she can't get anything else. I would recommend going with var instead or reconsidering your motive for using AAS in the first place. It is my belief that as a woman who does not compete in BBing or PLing, you should seriously consider staying "natural." In this case, the risk outweighs the reward. Those who compete go into the process knowing they are going to have some issues at some point. Some are luckier than others in this regard. As I always say, I cannot tell anyone to do anything, this is simply a suggestion based on what I know.
And I'm with BR on the anabolic/androgenic ratios...they are not as important as people claim them to be. The fact that the anabolic/androgenic ratio for Methyltrienolone is even listed at some sites (like 12000/6000) makes me think that that number was in fact a guess. So, it would seem more logical to go by the personal experience of others rather than a chart composed of studies done on rats with no nuts. I would also believe that a non-competing female wanting to use a drug that not many competitors even use would not be the best idea
