^What he said.
There isn't any way to know for sure whats in such products, so the best advice is to avoid them.
We don't allow this type of discussion in Other Drugs simply because lab tests have shown that some manufacturers will sell a variety of chemicals under the same brand name, so its next to impossible to know for sure what a mystery product is.
I'm going to go ahead and close this, please PM me if you have any questions about this.
