If you want to lose a few pounds, the Acai supplements will help a little and they should be fine with MDMA use.
80% of weight loss (or any physique change for that matter) is proper diet. The fastest way to lose body fat is to limit carbohydrate intake, cut WHITE CARBS altogether, and get away from fast food. Supplements only help a little bit, but if you rely solely on them you won't see much, if any, change in your weight.
You could also try cycling carbs, I'm around 4.8% body fat, shredded from weight lifting and dieting and cycling carbs worked wonders for my summer cut cycle that I started in the spring. Cycling carbs would be like 3 days of less than 175g carbs per day, then on the 4th day you reset your cycle and eat 400+ grams of whole carbs and then repeat the cycle.

If you want to gain weight, eat a high protein, high calorie diet. Take your weight in pounds, multiply it by 20, and that's how many calories you should be eating per day. Out of those calories, at least 40% if not more should be in forms of protein. Another 40% should be in good carbs like whole wheat bread, and the remaining 20% comes from "good" fats, such as polyunsaturated and monounsaturated fats that you would get from foods like salmon and extra virgin olive oil.
Last winter, from November 1 to March 15, I gained roughly 10lbs of muscle by following that diet plan and weight lifting where i kept my rep range from 4-10 reps at heavy weights. Sports supplements (creatine, beta-alanine, arginine-akg, etc) for that plan accounted for MAYBE 5-10% of my overall change in physique...
I agree that creatine is a great supplement for increasing mass and strength, but it's only a temporary solution. Once you get off the creatine, the extra water in your muscles dissipates and you're left where you started. Creatine should be used and cycled to get past a plateau, not as the sole source of your mass gain.
Too many people rely too heavily on things like "fat burners" or supplements... looking for that magic pill that will change how they look, when the real change starts at the grocery store.
