it garnered a following in the uk and germany fwiw because it was the first time they ever got amentoflavone, and the amp citrate filled the craze gap before everyone could build up a resistance. if thats exactly what you are looking for its probably an ok buy, but it is almost certainly overhyped because it had good timing, probably none of those who are huge fans of it even know what amentoflavone is, and stack3d is... actually pretty bad for actual reviews if you ask me.
