Don't hesitate. Just buy it.
I'm a mother of a 2 year old, 29 yrs old, 5'8" 125 lbs...active, great diet, take many different supplements. You would think that is all I would need. Nope, I was still fatigued all the time, muscle aches, cloudy headed, fuzzy memory, constant migraines, irritable, junk food cravings to fight off, etc. I was beginning to feel like I was 50 years old and feared any more of a decline that I wouldn't be able to handle with my son around.
I've tried the neurotransmitters route, hormonal imbalance, tons of water, whole food diet, fresh fruit/veggie smoothies and juicers, any supplement you can think of...all still hit or miss, up and down until this. All I can say is WOW. I mean, the diet is still a must but on top of this it's a home run. This has balanced me out and continues to balance me out more than anything else has. No junk food cravings at all, no more migraines, irritability drastically improved, no longer fuzzy headed or a shaky memory. We went on a vacation to the caribbean and I didn't take this with me. Around Day 5 I was dragging and nearly sucked dry of energy by the time we got back home. I immediately opened the fridge, took this again, felt a surge, and was good to go after a brief nap- zipping around the house, cooking dinner, laundry, etc. This stuff just amazes me. It isn't a drastic change as you might feel with something like Red Bull or 5 hour energy that I gave up a while back, but it is a more natural, your body is no longer fighting for energy or struggling with a deficiency type of boost.
Again, just buy it, it's worth a try if you are struggling like I was!
