Force Factor LeanFire with Next-Gen SLIMVANCE Advanced Thermogenic Fat Burner for Weight Loss with B Vitamins and Capsimax to Boost Metabolism, Increase Energy, and Enhance Focus, 60 Capsules

I take 1 (the dosage is 2) any day that I am feeling tired but need to get things done. I tried taking 2 but felt too jittery. One capsule is perfect for me. It gives me steady energy with caffeine and capsaicin for about 5 hours. That's usually all I need to accomplish my daily tasks and not keep me awake at night. If you do take 2 capsules, I recommend that you drink decaf beverages so you don't get too much caffeine. I didn't experience a lack of appetite but I didn't eat a lot because I was busy. I take this about once a week.

Love this stuff, can't go without it. I've been taking forever, I feel and see a significant difference very shortly after I run out if I don't have a backup or don't restock right away. I hope they never stop making it.

I have bought this several times! It gives me lots of needed energy.

This product works very well but if you have a sensitive stomach, it’ll make you a little nauseous.

THIS IS AMAZING NEVER CHANGE THE FORMULA AND KEEP THIS IN STOCK!!!! If you are trying to lose weight, this is a go to it doesn’t make me break out. It is literally perfect for losing weight fast as hell it works like a charm every single time and it gives you so much energy. If you take this, you will be awake for a good amount of time.

I took it once! Once. And I didn’t even take two pills I only took one, I ate 20 minutes prior to taking and around 2 hours later my stomach started hurting really badly so I started drinking water, 30 minutes later I threw up all the water and food I ate, it’s been about 30 minutes since I threw up as I’m writing this and my stomach still is hurting and I coughed a little bit ago and threw up again. If you have a sensitive stomach this product is not for you. And that also says a lot figuring my stomach is sensitive in the sense I get stomach aches but I don’t throw up literally ever not even when I’m sick. I had the stomach flu and I threw up once, so that says a lot.

I took the two pills (one dose) with a piece of toast and within 15 minutes began my workout. During the 45 minute workout I did sweat more than normal. After about 1.5 hours of taking it, the jitters hit me hard. I'm the one that as soon as I consume an energy drink, the jitters hit me within 10-15 minutes while the two tablets took 1.5 hours. About 2 hours after taking, i had to take a number two. After eating a snack, I had to go again. I will reduce the dosage to one tablet to see how I feel. I do not like the jittery feeling. I'm writing this review 4 hours after taking and I'm still jittery and stomach on edge. It appear this works by making you so jittery you do not want to eat. If you do eat something, you will soon poop it out. I also notice this did raise my blood pressure by about 8. After the half dosage, I will update this review.

I've been taking this for 2 years and I've lost 90 lbs. It gives you a boost of energy and you sweat a lot. I only took 2 pills a day, I was concerned about taking too many pills. I recommend this to anyone that is needing energy and wants to burn fat. These pills combined with exercise and a healthy diet you'll see results.
