I was sent the above to trial 3-4 weeks ago and have been running since. Started at 1 cap daily. Didn’t feel much if anything to be honest however my Fitbit reported a steady increase in resting heart rate through the morning which is Defo of benefit to me as I don’t feel any noticeable stim effect but increase in heart rate both resting and through cardio. This last week I have been taking a second one around 6 hours after the first. I would say the effects are very mild compared to some fat burners but for myself I prefer this. It hasn’t helped with energy levels later in the day either but there is no crash like off some of the more stimy products. My mate was disappointed when I gave him. Few as he likes the stim effect but it’s each to their own with these products. I’ll be getting more n running through prep I reckon just for the slight increase in kcal burnt as I feel little things like this are important without nailing Stims.
