You should look into beta-aminoisobutyric acid (BAIBA). Among a few other things it upregulates PPAR-alpha, which controls many of the enzymatic steps involved in fatty acid oxidation, upregulates transport proteins that carry fatty acids across cell membranes, and reduces amount of triglycerides in the blood. It also inhibits the signaling of certain pro-inflammatory proteins so it has anti-inflammatory effects as well. BAIBA is probably the closest thing to cardarine as far as being a PPAR modulator
