I've been taking L-Theanine and a caffeine supplement for over 12 months now. Help me kick start the day and remain focussed without the caffeine jitters.

Also during times of anxiety L-Theanine and 5-HTP from this site have help members of my family through bereavement and other tough times.

Service Rating: szybka dostawa, dobrze zapakowany towar, ogólnie dobra informacja o produktach na stronie.
Product: nie daje skutków ubocznych, kapsułki niezbyt duże, dają się łatwo połykać, ogólnie samopoczucie mam dobre, ale za krótko używam, żeby konkretnie coś powiedzieć
