This stuff is Amazing! Whether you make a nice cold Terrere or a hot Mate, watch out! Best taken with your wife/girlfriend when you have nothing to do but get intimate. Don't say I didn't warn you! Also works awesome if you have a hard day of work ahead, or a serious workout. I have used it to get my energy AMPLIFIED when preparing for any outdoor activity-hiking, climbing, surfing, running, etc. I LOVE this stuff, it will keep you seriously focused and energized without depleting you, I used it to burn through my bachelors degree in 3 years.
