This is a bit late, but these are two very different products. Virtus is all about inhibiting estrogen...if you're holding water weight due to estrogen, then Virtus will help shed that pretty quickly. In the long run, Virtus will help burn fat and increase anabolism...but the effects you'd see early on would likely be related to water weight.
how's the run, now that you've had a little more time with it?
