Taste good. I don't really noticed any energy increase but I would say it moderately reduces your appetite.*

I take this first thing in the morning. Pineapple is a little too tart for 4:30 in the morning.*

The ACV taste is a little hard to hide and I liked the original formula better but I will continue buying this product even with the new changes.*

Great flavor! Wanted something that was stimulant-free to alternate alongside Allmax Amino Cuts. Amino Cuts anytime before noon and then Rule 1 Lean anytime after noon.*

Get a little hint of pepper taste towards the end but it does heat me up and I like the Tim free option so I can still have coffee later in the day. Mixed well in shaker bottle.*
