This basically product basically does what it's supposed to. I have recently been using powdered caffeine pre workout and adding my own ingredients, instead of pre made formulas As with most of their products, this is pretty high quality and provided good clean energy. I have tried a few different brands, and although this may be a little more expensive I believe it is worth it.
This stuff works very well. I believe it its a little bit stronger than some of the other 200 milligram caffeine pills i have used in he past. I would pop one of these guys and be good to go. It would enhance my mental clarity and alertness. I had a great boost in energy anf focus. The price is very competitive with other brands maybe a bit more expensive but priced well. Sometimes i even breakthe cap in half to only use a portion of the caffeine.
Caffeine is the main ingredient of all stimulant based preworkouts. It is the main reason you get all of that energy and focus when taking a PWO, but it is much cheaper to just buy ingredients like caffeine individually. You can also get the dosages right, instead of paying for expensive PWO supps with underdosed or mixed dosed ingredients. Supplement in tablet form like this if you don't like the taste of coffee, or if coffee makes you.. need to do other things than work out, or so that you can get a precise measurement (like 200mg). I use it in conjunction with 5g of creatine (daily). Keep your liquids up!
I will take usually half a tablet that I cut with a knife as part of a pre-workout. These particular pills don't seem to "rush my system" but is a more steady energy for me. I've taken other caffeine pills or pre-workouts w/caffeine and this was easier to handle for me.
