Very good, but...

Posted by 5620678987357385644 on Nov 09, 2016

Thjis is very good (not a s xananx to imeediatley remove any anxiety you have at the moment). However: If i teke it in panic attack or when im anxious, it alomst does noithing except that you feel a littel resistance that you can handel. However when im alreally good , or relaxed iand i take iot ...i feel very amazing. THe same is true for theanine and cofee. If i am stressed, nothing almost helps (except xanax). But if im somewhat relaxed and take theanine and coffe i feel amazing and focused . It takes at least 40 minutes to hit. (I usually take 200mg and sometimes 400mg)

No Help At All For Insomnia

Posted by 5305309898245582342 on Jun 09, 2015

I purchased this product after reading an article about it's potential benefits for treating insomnia. Taken exactly as directed, 400 mg (2 capsules) had no effect whatsoever. The recommended dosage is 200-400 mg. I even tried taking 600 mg, but had the same result, which was zero effect. Very disappointed.
