It gives me a feeling of added alertness within 30 minutes of taking the product. Not a buzzy type of high, or anything like that, but more a a controlled alertness.

At a little over 12lbs, I found I needed to reduce my dosage from 5 to 3 capsules a day. Also, if you are sensitive to caffeine or metabolize it slowly, avoid taking this too late in the morning as it may disrupt your sleep. Taking 5 capsules first thing in the morning definitely kept my focus high but I also had trouble staying asleep at night. Three capsules worked better for me including taking a two day break after 5 days on.

Great product

Excellent
