Definitely both good choices and yes, stackable. Personally epitome was very hit or miss for me on appetite tho... some days SUPER high, other days, somewhat less than normal. rarely just "normal". I would say more high than low though unfortunately.
Personally, SNS Lean Edge and the OG PES Shift (not the new one... its crap) were the only 2 non stim products that did anyhitng for my appetite (usually pretty high). Current formulation of SNS Lean Edge is my go-to and would be my recommendation. Realistically you could even stack it with those 2 evomuse products for a super comprehensive stack
