Summary: Is Ultra-40 a supplement worth investing in?

Body: I recently decided that I was sick of the way that I looked, being tall and pretty skinny (about 165lbs/74.8kg), and I started on the 5x5 Stronglifts program that was recommended on TRP. I'm happy to say that it's helped immensely and in the span of about 2 months, I've put on at least 10lbs of mass, and looking much more like a man then a stickbug.

Then one of my friends, who also lifts, told me about Ultra-40, and said that if I took 1 tablet per 10lbs/4.5 kg that I weigh it'll help to get me bigger much faster.

It's something I'm very interested in, because if It'll help me gain mass quicker, that would obviously be extremely beneficial in raising my SMV. I just want to know if it's worth it/it will actually do what I was told it does.
