Awesome product if you want to stay focused and suppress hunger

I took my time to really experience this product. I've been taking it for about 3 months now. I was feeling so sleepy and unable to focus for my long days of studying that I decided to try different energizing beverages and I found out that all of them have the same in common. High doses of caffeine. I could just drink a cup of coffee and I like drinking it with cream but it usually gives me reflux so I looked for another way to have my caffeine dose and this pills work wonderfully. I'm also practicing intermittent fasting to lose weight and with this product I can easily workout in the mornings feeling energized and suppress hunger for about 5 to 6 hours having one of this pills. It's definitely a great product and I recommend it.

Absolutely love these. So cheap and they come in the ...

Absolutely love these. So cheap and they come in the perfect dose. I have dropped my preworkout and now just take this. Let's face it, your preworkout works well because it's loaded with caffeine. Unfortunately all the other stuff that's thrown in often upsets my stomach, especially when taken on an empty stomach. I take these on an empty stomach all the time with no issues. I used to drink coffee every single morning for a boost but now I can take one of these and get the same effect. One fun tip for people who have issues getting up the morning: set your alarm for 45 minutes to an hour before you have to wake up. When that goes off take one of these and go back to sleep. By the time you have to wake up that caffeine should be in full effect and I have a MUCH easier time getting out of bed that way.

Caffeine, pure, undiluted caffeine.

I'm not a big fan of coffee, I don't like the taste. I've had two kidney stones because of soda and energy drinks, so I needed something different to get my wake up in the morning / energy to last the day. This is one of the best purchases I've tried. 300 mg is a lot of caffeine if you're not used to it, most cans of soda have 41 or less mg, this is pure caffeine in all its glory without any of the unhealthy additives in soda or energy drinks. 300 mg is a lot, it may be worth trying to cut these in half at first to see if 150 mg is enough for you. I started with the full 300 mg and used to get a little jittery but thats worn off either from tolerance or practice I'm not sure. I still feel alert and awake when using these. 10/10 recommend if you don't like coffee or just want to save money but keep your caffeine pick up.

Better than coffee

Quit coffee because of heart burn. I do miss coffee, especially in the winter. With these I don't get the crash that I did with coffee. You take one in the morning and you're just awake. Not bouncing off the walls, just awake. When I first started taking these I did notice that I would get a little jittery if i didn't eat anything. I've been taking these for about 2 years now. Both in the morning and as a pre workout because those real pre workout powders give me crazy heartburn to the point of nausea.

This is the best caffeine pill by far

This is the best caffeine pill by far. I have used many different kinds and have yet to find one that i like more than this brands. The rush is nice and controlled and lasts a long time, the effect you would get from an extended release drug. But you get that initial jolt of energy without the crash at the end. Love this product, have been using for years and it gives me the same effect. Ps I'm an coffee-colic at work, especially during night shift, but this pill is life. Legit life changing.

Save your teeth and stay awake FOREVER(?)

My second time using these, first time I didn't split the order with a buddy. Love these things. Probably love them more than I should. I regularly drink 6+ (8oz) coffees daily and these save me from feeling like I have to use the bathroom every 4mins, also saves the coffee stains on my teeth (per my dental hygienist). The pills taste a little like warm plastic at first out of the bottle, I set about 40 in another pill box for immediate use and then rotate in new ones when the reserve is low - this eliminates the hot plastic taste. The effect on me lasts about 7hrs (8am-3pm) and I don't have a crash per say. I never feel like I'm draggin, just that my speed rage induced workforce is lacking luster around 3pm. I also take a couple prior to obstacle course races (Spartan, Warrior Dash, Rugged Manic, etc.) for the pre-pump without all the bladder filling come race time.

Excellent daily substitute for coffee, if used responsibly

For years, I used to drink 2 large cups of coffee every morning and then more throughout the day. Coffee tastes and smells great, sure, but it was really just the caffeine I wanted. In that case, a little over 2 years ago, I switched to these caffeine pills. I'd say that each pill is about a strong cup of coffee and taking 2 in the morning as soon as I wake up is comparable to my old coffee habit. Also, the experience of taking caffeine pills daily is much different than coffee. First off, the transition from pills to coffee was somewhat rough on my stomach at first. Second, the onset of caffeine pills feels different than coffee. Coffee is far more of a sudden hit, while the caffeine pills have a slower onset. On an empty stomach, the caffeine pills hit in 1-2 min. And third, you need to be careful with how many pills you take. 2 pills might be awesome, but 3 pills might push you into jittery-caffeine limbo. It's hard to accidentally drink an extra cup of coffee if you really don't want it, but it's easy to take an extra pill. I suggest starting with a low dose, perhaps 1 pill or 1/2 pill in order to feel how it affects you. The pills are pretty easy to break in half. Overall, if you figure out how to use these effectively and responsibly, these pills are an excellent daily substitute for coffee.

Effective even I caffeine resistance

Works as advertised, won't overdosed since human can take up to 600mg caffeine per day. I took a lot of tea starting from childhood as an Asian, so most of time coffee totally not working on me. Including coffee, sometimes even a weak energy drink will make me sleepy instead of keeping me awake. I believe part of the reason is sugar crash. Taking this caffeine tablet for 1 month and I feel great about it. After lunch, one tablet can stay me awake in afternoon hours without feeling uncomfortable. Also, as a replacement to coffee/energy drink, I can save my stomach for fruit/snacks/other drinks I like. To avoid being addicting to this, I only take one table per day when I feel sleepy.

I developed very bad stomach pains whenever doing so

These are my secret weapon that got me through law school and studying for the bar. Rather than taking excess coffee breaks, I could have one of these and get back to work. Word of caution, however, try not to exceed more than 2-3 per day. I developed very bad stomach pains whenever doing so.

Great!

I've been using ProLab's caffeine pills for over 4 years now, and I can't imagine life without them. Going to the gym? Take 1-2 pills depending on what lifts I'm doing that day, then I'm off to bench press some wagon wheels and squat the whole rack. Running on low sleep? Pop a pill to get that shot of energy which lets me pull through whatever tasks I need to do before I get to nap time. I'm not a coffee or tea drinker, so this is a must-have for me. The only side effect that you'll likely run into is that taking 2+ pills will absolutely ruin your stomach and send you to the toilet after 20-40 minutes. You'll have a rough time, but this is just a normal occurrence when digesting a large amount of caffeine and not something specific to this brand.
