SNS Leand Edge gets a lot of good rep and it's a great stacker, as it's non stim. I'm about to add that to my cut soon, but it will be the first time for me, so no personal opinion yet. I'm hoping for appetite suppression first and foremost and a little metabolism increase would be nice. It should stack well with the new CEL Lipo Elite, which has one or two of the same incredients, but not amounting to too high of a dose, according to Steve from SNS. And Lipo Elite has a few other ingredients and some mildish stims.
I think Synephrine solo is allways a nice addition to a cut, if not included via some stack (Lipo Elite includes Synephrine) or taking a lot of stims already. It's mild enough to not mess with sleep too easy, but offers some appetite suppression and a little boost in energy, especially if stacked with caffeine, wether from a supp, or just taken along with coffee.
SNS Reduce XT can be a nice addition to a cut, especially on the latter part, where cortisol can start to crank up.
I know you said you're looking at SNS and CEL, but I'll just mention, that Apex Alchemy Ursa Major (topical ursolic acid) is my favorite supp to help with cutting. Ursa+Reduce XT probably my favorite supp combo for cutting thus far. I'm 3 weeks in to my cut right now and adding Ursa in today, then Lean Edge the next week and I'm hoping it to be my new favorite combo = ) I also have Reduce XT on hand and I'm taking Synephrine here and there and also nicotine pouches (which probably isn't the smartest idea for everyone, but that's just what I'm doing).
SNS Recomp20 could help with muscle retention, but I don't know too much about it yet. I have seen some positive reviews around.
