Lean Edge and Ab-Solved is a great cutting stack.
As for caffeine or stimulant based thermogenics, that's entirely up to you if you want to add one to your stack. If so, a lot of people love stacking Thermagize XT + Lean Edge + Ab-Solved.
You may have typo'd - when you said 'So I need caffeine pills and creating?' above, did you mean Creatine? If so, I would suggest a type that doesn't make you hold fluid weight like our Creatine HCI powder or caps. Creatine Monohydrate is great for some people but for many people, myself included, it can cause fluid retention to where we can't really see our progress in trying to get lean for the water weight.

It's okay. It's a forum error that I know they've tried to fix forever. A lot of people don't know, especially when they're newer to posting. Hell, I've known about it and still accidentally done it myself before.
That's understandable. There are some supplements that you want to have been working out consistently for longer before you take them, but there's nothing wrong with taking fat loss products after training for just a few months. Many people take these when they're just starting training or not training consistently.
