It was in late 2005 that the status of methasterone, in addition to that of four other designer steroids, as an AAS was brought to public awareness by an article published in the Washington Post .  Don Catlin of the UCLA Olympic Laboratory, who conducted the studies, noted methasterone’s similarity to drostanolone. A warning by the FDA was issued soon after to the general public as well as to the distributor, Designer Supplements LLC, for the marketing of this compound.  Methasterone was subsequently added to the World Anti-Doping Agency (WADA) list of prohibited substances in sport.  Despite all of this, methasterone has resurfaced within the supplement industry on several occasions since its banning by WADA. 
Truthfully, I cant be confident predicting more than a 5lbs gain with the use of Undestor , because this product has a very odd property, and that is the widely varying effects it has on test subjects. In one study I read, four test subjects were each given Undestor , and one had a huge surge in testosterone levels going up to /L and the other only had a /L level(5)! The remaining 2 test subjects fell in between those levels. I am speculating that the differences experienced by the test subjects were primarily due to the variances inherent in the lymphatic system. But to make matters even more inconsistent, there is no evidence that those variances wouldnt occur within the same person taking Undestor (. you get a huge surge in testosterone one day, and a very minor one the next day). This may be due to variability associated with whether this stuff is taken with food or not. Since it operates via association with your small intestine and lymphatic pathways, taking it with food greatly enhances its bioavailability (9), and this may be a case of "problem solved" but Im hesitant to close the books on andriols absorption problems so quickly, for now, well just say you are spending your money much more wisely if you take your andriol with meals.
