Extended Release Caffeine Pills + L-Theanine + 200mg for Energy & Focus + No Jitters, No Crash + Natural Caffeine Supplement - 60 Capsules

As a Class A HAZMAT CDL driver, I can tell you that alertness determines life or death in a split second on a daily basis. These time release pills are a LIFE SAVER when we're tired. I've never taken anything that makes me feel not only alert, but also makes me feel like I had a good night's rest while operating on only 4 hours of sleep! I'll use this product as long as they manufacture it!

On daily, I average 300-500mg caffeine intake via espresso, kcups, karak chai, v8 energy or some combination of these forms. When I took this last year for Ramadan fasting, I noticed these helped relieve my headaches, crashes and heavy eye lids throughout my workday. I took two pills usually, and few mornings with less sleep night before, three pills would do the trick. These were super effective, and i had sustained energy levels. They did NOT upset my stomach or make my heart murmur or anything since I already have a high tolerance for caffeine.

Just ok. I took one it wasn’t enough. I took 2 and went to sleep. The sweet spot is taking 1 waiting 2 hrs or so and taking another one.

Coffee gives me headaches and energy drinks have a bunch of unhealthy crap in them. So I was looking for the healthiest caffeine I can find so I tried these. I've only been taking one in the morning and it seems to give me steady energy throughout the whole day. I have a low caffeine tolerance, but I was very impressed. All other forms of caffeine I've tried seem to give a spike then a crash, but these don't. Honestly it's amazingly cheap too compared to making coffee or buying an energy drink everyday.

Heavy chemicals and cologne like smell and taste. Not as expected or orderd

This is a good supplement on those days that I didn’t get enough sleep.

I've tried a lot of different caffeine products and most still have a little bit of a jittery feeling so I was expecting this one to have that too. However, I was really surprised that, while being effective, it wasn't causing any of the jitteryness or clenching my jaw or any of the side effects I usually get. I also didn't really feel tired or gross when it wore off. The amount seems perfect and it seems to last a bit longer than alternatives like no-doze. I really like this product and would purchase it again.

I bought these as an extended release stop gap replacement for the (not sadly discontinued from what I can tell) Puritan's Pride extended release pill... and they do NOT hold a candle to a caffeine that has nearly 2.5 Times LESS caffeine than what this one claims to have at less than $4 a bottle (pour one out for the last good value of 2023). As a matter of fact, I can't tell if they do anything, really... and will often take 3 along with a fast acting MuscleTech 225mg caffeine pill in the hope it might prolong the MuscleTech pill. Can't tell you if it does or if it's the additional caffeine I need to consume less than 4 hours later that's actually doing the trick. The kicker to this sugar pill saga is they put a QR code for a discount (presumably on a repeat order) on the box that DOESN'T EVEN WORK... taking you to a 'coming soon' site! Talk about fly by night! This isn't just poor form, but do you really want to trust putting something into your body from a foreign company that can't be bothered with filling out their template forms?!
