I gave RPN's Havoc a go, which is exactly the same compound. It is a very dry steroid, nice strength gains. I did not see much mass gain, but have read about some adding 10 lbs with one bottle cycle (these are mostly kids in early 20's weighing under 200 lbs). It is methylated, so run as you would any other liver-toxic compound.
You can actaully use this as an anti-estrogen; it's un-methylated parent compound is used in Japan to treat breast cancer. Not sure if it's a SERM (like nolva) or an armoatase inhibitor (like Letro). Many people (see description above) have actually cleared up gyno completely using it.
It's also OTC.
