Just to add some comments and get this forum going again...
Ive tried Opticen, vanilla flavor (several buckets now) and its great tasting stuff. Even better than the sugary Nlarge I was using.
I also used thermocin for about a month, I did get some fat loss results and didnt get jitters... Im pretty caffeine sensitive since I dont normally take in any.
As for the service, I havent had any problems yet, it only takes a couple days from order time till its at your door. Ill continue to order and I think Ill try the Nitrean next time
