USP Labs' record of introducing novel ingredients to the market has been crap. Virtually all of their useful products are a combination of already known ingredients coupled with really good marketing. It would be cool if Compound-20 did what they said, but I am not blowing my money to find out. I will wait to see
I have only sampled OEP, but wasn't a huge fan. It has old school yohimbe in it, and that stuff is pretty harsh for me. I also question the wisdom of stacking DMAA and yohimbe together, but people have seemingly used it safely (and successfully when combined with a sensible eating and training regimine).
