Yes, but I doubt it'll have a usnic component.
Incidentally, the FDA has *never* specified what ingredient they claim is liver-toxic. We've only assumed they're referring to sodium usniate.
I haven't found any research that suggests a liver risk, and I've emailed Syntrax and several other sellers of usnea...all of them replied, and all of them agreed that they cannot find any research that implicates usnea in liver problems at all. Not only that, but there is research (cited above) that usnea is actually quite good at preventing cancers, killing tumors and harmful microbes, and detoxifying the body!
If anyone has objective research about usnea and the liver specifically, please mention it. I can't find any.
As for hospital trips, we know that usnea is an allergin to some people. I suspect that.
Meanwhile, I use lipok in a 2 weeks/1 week on/off pattern, along with NAC and milk thistle and oil of oregano. So far my fat loss is spectacular.
Hell, I may even try DNP someday.
