I like the dicaffeine malate, nice energy from that. The PEA and paeonol combo doesn't work for me, paeonol isn't an effective MAO-A/B inhibitor so that's not too surprising. The salvia, GCBE, and piperine combo looks like it'd be great, helps sensitive to insulin, helps you enter AMPK, and decreases fat storage. I'm only halfway through my tub, but I like it enough to consider repurchase, if only for the salvia.
