I like mine cheap. It's all 200mg of caffeine people. don't spend three times more for name brand caffeine. When I don't feel like making coffee, I pop one of these puppies into my mouth and it's go time. If you want to take a power-nap, do it after you take the caffeine. How? When your really tired midday, set the timer for 20 minutes (no more, or you'll fall into REM and wake up groggy), take one of these and take the nap. You'll wake up 20 minutes later super refreshed. Backup PETA, by puppies I meant caffeine. 5 stars

+++A+++ Quality I wasn't sure whether to try this brand of caffeine, but given the company's excellent reputation w/ other products, I decided to try it. I'm SO glad I did. I take caffeine pills everyday, and I know the difference between Quality caffeine and generic caffeine. This product is Definitely high quality and comparative to No-Doze. Comes in tablet form, so it is possible to only take 1/2 if you need a boost, but do not want to take an entire tablet :) +++A+++ 5 stars

this product works as advertised. I have a high tolerance for caffein, and this is an easy way to avoid drinking 5 cups of coffee (which i hate) 5 stars

I've been using this brand for many years, for getting up in the morning as well as exercising. Gets me up within minutes of taking them and helps me to exercise more efficiently, also with more reps per set!Prolab Caffeine- Maximum Potency 200 mg, 100 Tablets 5 stars
