The thermo effect was not really to pronounced but once you started sweating you kept sweating for awhile. I did have alot of sweating during my workouts but I do tend to sweat pretty easy.
You will like your run of this just make sure to dose once a day till you "need" that second cap to make the bottle last awhile.
Thank you for your feedback !
