Well, I've been a heavy user of AX's previous Slim X for energy, focus, and appetite suppression (you can search the net for my username + slim x lol) and I wasn't really impressed with Slim FX and the new Stimulant X, but I've found some love in SuperSize!
I'm SUPER picky about my stims, I usually combine with noots for a reason, and *nothing* otc is comparable to the late SX, and this is not a discussion about that, so I'll just give a thumbs up for SuperSize since it's THE most pleasant and smooth stim I'm experiencing on the market currently, IMO.
DS' Craze is more "effective" for focus, but it's too much stim at the moment, I'm liking Supersize more.
Had to give it a trial and it's a fantastic solution in powder form. I "micro" dosed SX too (splitted the cap), and Supersize offers that option too in easy powder dose.
It's really versatile and can offer stimulation in various settings (like 1/2 scoop in the morning to replace coffee when you need to do desk work, or 1-2 scoops before a workout, etc.)
It's a very refreshing flavour too, and goes well with a couple drops of vanilla extract (ymmv) and some crushed ice.
Home made "energy drinks" for the win! You totally decide how strong you want it.
It's stackable too (noots, ultra reps, other misc. stuff), you almost forget actual coffee exists.....
Good work, AX!
