I really, really doubt its anything like winstrol. That is just marketing hype.
Here is some info on revolt, from its manufacturer.
"REVOLT is legal because it is a progestin, and before anyone thinks "birth-control", remember that the illegal steriods trenbolone, nandrolone, and Methyl-Dien are ALL progestins too.
As a progestin, REVOLT is structurally related to the so-called abortion pill RU-486 and as such acts as an "anti-progesterone". Yes, this means decreased estrogen-like effects and the potential for an increase in libido.
Research suggests that REVOLT has a half-life of about 6 hours, though it appears that it is closer to 10 hours based upon plasma levels maintained in our test subjects. It is not a 17-alkylated analog thus having very low potential for liver toxicity.
Results? REVOLT users report increased strength and recovery with amazing long lasting pumps the very first week of use.
Progestins do not aromatize to estrogens and being a 5-alpha-reduced analog prevents conversion to DHT. Naturally the lack of estrogenic activity translates into low water retention and solid gains.
