If you're looking for lean mass, I'd look at other products like Anabeta Elite (Invalid Link Removed) and ArA (X Gels -- Invalid Link Removed , X Factor) that were mentioned, or an -epi product or PA (soy lecithin granules).
I enjoyed the OG version of Slinsane, but now utilize Slintensity. But that falls into the category of "if I'm having a lot of carbs in one meal/sitting, I'm taking this beforehand" and that's generally it.
