I've experimented with SlinSanev2 (4-5 bottles), Slintensity(1 bottle), and now Recompadrol(1 bottle). SSV2 is my favorite, Rcomoadrol is still fairly new to me. I can't tell much for fat loss with GDA's yet but I can say I'm far less bloated after giant meals. I've put down 600g of carbs in a day and never felt lethargic or anything. I almost always take it with my preworkout meal (1+ hour out) and I actually feel a bit more energetic.
