What would you want to be taking it for? It's banned from shelves where I'm from and it's just a stimulant, have some caffeine instead.
Very effective stimulant that is a banned substance in competitive sports and has now been removed from the shelves in most countries that I know of.
It was in the original Jack3d, but that formula has been banned specifically because of the 1-3. Enzo Mac failed a drug test because he took it. Personally I'm not a big fan of **** like that anyhow. Most companies don't tell you the quantities of the ingredients and just slap 'Anabolic Blend 9000 Extreme' on and give you the weight of the blend. ****ing stupid that they're even allowed to do that.
