Hey bro - at one time I was interested in it as it sounded like a reasonable alternative to DNP. There are two different derivatives of Usnic - can't remember what they are. There was quite a thread on this board about it and I concluded it wan't worth wasting money on - cleaned out all my links to it. The inexpensive one seem to have some toxicity issues with it.
The demand for their current products is so high, they have trouble managing them, so I don't think a new product is going to come out any time soon.
I know that they have a couple of SICK fat burners in the making, one is a spot reducer, but when they will reach production level, I have no idea.
