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.

Mahtava tuote!!! Suosittelen ehdottomasti!!! 1. kapseli klo 19:00 ja seuraava 22:00 ovat antaneet rauhalliset pitkät yöunet (8-10 tuntia). Tällaista ihmettä ei ole tapahtunut vuosikymmeniin.
