RE: Cissus plus ECA on cut ?
I can't see any issues to be honest. Any side effect which could arise in the very rarest of oppurtinities are singular to each compound, so won't compliment each other in that regard.
If you're fine with your diet and cardio then I would say that these two alone would be fine. I'm a fan of megadosed ALCAR, 6-10g's daily, and it's relatively cheap.
