This Caffeine powder is pure and when taken in the correct quantity, which I find is one small scoop, works very effectively. The scoop is provided in the container so it makes for easy measurements. If you need that little boost before your work out, or just a morning wake up before work then this is a cost effective way of doing so because it lasts a very long time. It also saves you buying a caffeine drink from the shop, like a coffee or an energy drink. Just thinking back, I used to spend a lot a day on coffee and juice for energy whilst at work and this worked out at around £100 a month. For one bag of 500g caffeine, it is much cheaper and lasts for ages. This powder is mixes well. I can take it with water because the taste is not strong and the taste is unnoticeable when mixed with diluting juice or the like. So for all these reasons I highly recommend this product. <B>Goes Well With:</B> water, diluting juice

If you have used pure caffeine powder before, you pretty much know what to expect. It may not taste very good when mixed with water alone, and the mixability isn't something to boast about, either. However, it works fantastically and you can feel the effects almost immediately. Be careful with the measurements, because even a small amount goes well above the daily dosage. It is, as a conclusion, laboratory grade caffeine at an incredible bargain.

This Caffeine stuff is great. Personally I hit the gym first thing at half 6 in the morning. I find it a rush to have a coffee etc. whilst getting ready, so I simply add 200mg of this to my glass of water/berroca/creatine/bcaa and within 5mins I'm wide awake and my eyes are like fog lights on full beam. <B>Goes Well With:</B> creatine/berroca/bcaa/beta alanine

This Caffeine is not effective at all if you are on any other form of caffeine-based pre-workouts, but if you cycle them on and off it works well as a pre-workout. It can also be used as a good wake up tool in the morning.

This Caffeine is not as effective as I thought it would be. The taste is really bad. I would rather drink a coffee to be honest.
