Buy it… Its good!
I’m on Day 3 of using this product, and I have to say — I’ve sweated more during my workout than I ever have before. I’m not a natural sweater at all, so that actually felt good. The energy boost hit almost immediately and carried me through the next two days. I could also feel a noticeable shift in my mood within the first 24–48 hours. It wasn’t anything dramatic, but I found myself getting up and moving instead of just lying in bed until it was time for work or the gym. That alone told me something was working.One thing to note: the very first time I took it, I did not sleep for a full 24 hours. My body was just going. I followed other reviewers’ advice and started with one pill, which I recommend. Even with the energy surge, I didn’t experience jitters, shakiness, or that anxious “wired” feeling some supplements cause. But I definitely used the bathroom more — increased bowel movements are pretty common with stimulants and herbal thermogenics, so that didn’t surprise me.From a technical standpoint, Zantrex contains caffeine and other thermogenic compounds designed to increase metabolic rate, elevate core temperature, and stimulate the central nervous system. That’s likely why I sweated so much and felt that extended energy lift. These ingredients can also influence dopamine and norepinephrine levels, which may explain the slight mood enhancement and motivation boost I experienced.Overall, I would recommend this product. I genuinely like how it makes my body feel — energized, focused, and more active — and I appreciate that it didn’t come with unpleasant side effects. Also, buy it here. This price is at least $10–$15 cheaper than what I’ve seen in other stores.

Fight that 2:30 feeling for less than $0.60 a day!!
I used to drink a pot of coffee per day, before that I used to drink 2-3 energy drinks per day. These pills give me the same level of energy as the aforementioned activities without the jitters or feeling anxious.Just to be certain I wasn't experiencing placebo effects I went off the pills and switched back to coffee. Right away I was feeling nervous and jittery and my thought patterns seemed cloudy. After a day of this I drank plenty of water to flush my system and began taking these pills again.Not only do these pills give me a constant flow of energy without the crash, I have noticed an extreme level of focus. My thought patterns are clearer and my productivity has increased tremendously as opposed to using caffeine or sugar supplements. These pills are really affordable as well, usually they can be had at less than $0.30/pill, and I take 2 ($0.60) on an average day which is less than a cup of coffee or an energy drink. Even on a long day when I take 3 or 4 ($0.90 or $1.20) it is still economically superior to other supplements that claim to fight that "2:30 feeling".I have been using these pills for six months and I have noticed a huge improvement in my general functioning and thought processes. I am a 31 year old male in average shape and also a full-time student. After over a decade of being out of school these pills give me the focus and stamina I need to stay alert in class and complete my assignments.In my personal experience Coffee and Energy drinks have too many detrimental side effects when compared to these pills. I also used to take nitric oxide supplements to try and stay alert, but those made me aggressive and caused me to feel as if I was vibrating. These pills give me a smooth, yet intense, flow of energy and focus that lasts throughout the day.Just a warning: start out with one pill a day first to test your tolerance. Drink lots a water and DON'T drink coffee, tea, soda, or energy drinks. The added caffeine will alter your results. After determining if one pill is enough, add another pill either with the first serving or later in the day.Personally I take 2 in the morning when I first wake up, around 5:45am-6:15am, and take a third pill no later than 12pm if I need another kick. I drink on average 96-120oz of water per day, and I do not drink soda or sugary juices and teas during the day. If I take these pills too late in the day, then I usually wake up in the middle of the night fully alert and unable to fall asleep again. I wouldn't recommend taking these within 6-8 hours of your bed time.Having said all of that I would recommend these over anything for people who need all-day energy without the jitters. The mental clarity and focus are worth the price of admission alone. If you want to be your best self and be truly "limitless" then buy a bottle today!

Better than most
I only use on Saturday and Sunday, milking around the house days, but two at lunch, and one to two in the evening seem to do the trick for me, at least better than most.Cuts my appetite and snack cravings noticeably.

Watch out for niacin flush!!!!
Ever heard of niacin flush? Yeah, neither had I. The photo is about 20 minutes after I took the recommended serving of two capsules in the morning before eating. I started to feel hot at first, then my face was burning. I looked in the mirror and the sunburn look extended down my face and neck, shoulders and in the crook of my elbows. I was terrified! I thought I was having an allergic reaction and immediately took some Benadryl. I consulted Dr. Google and found out that high doses of niacin cause a sunburn-like rash but it doesn’t last more than a few hours. I was supposed to head into work in the next 20 mins but ended up calling in sick. I looked like a steamed lobster for two hours and felt like a bag of garbage on the comedown probably from the Benadryl as well. I couldn’t rest because my heart was racing due to the caffeine content.Apparently a high dose of niacin is over 500 mg. These pills are supposed to have 50 mg or less per two pill serving. I figured the quality control at the factory is way, way off. I may be sensitive to niacin however, I have taken weight loss type pills before and this has honestly never happened to me.Bottom line, avoid these pills. If the niacin content is off, who knows what else is?

Works well but caused migraines
This product caused migrains as soon as I took it. I had a migraine for over a month and realized that it was the product. I found that it wasn't the caffiene but one of the ingredients that was causing. The product works well but I need to stick with the Blue Zantrex.
