Personally I would be wary of taking Craze for very long. I finally found out what this orchid extract was all about... turns out it contains 3 different Phenylethylamines... in other words, it is chemically 99% identical to amphetamine. I guess you could say that this is a bath salt drug in the form of a PWO?
Here's a good writeup on the three compounds.
There is currently a lawsuit about these supplements, and I think it even alleges that they used actual amphetamines, so the label may not be on the up-and-up... They allege that it is not actually a plant extract, but synthetic chemicals. This is similar to the problem the 1,3d supplements had, where they would call it "geranium extract" but it actually contained no geranium at all (because the plant version is ineffective in humans)
Here is a good writeup on the lawsuit.
Something to consider, if you care strongly about what goes into your body. Especially if you have to take drug tests for work or sports.
