When all is said and done, Stacker 3 is presented like many weight loss supplements. While it’s claimed to boost energy levels and burn away fat, there is no clinical evidence to support this on the official website. Furthermore, it would be nice to see some customer testimonials, a money-back guarantee, a full product ingredient list and free trial samples of Stacker 3 offered on the official website. When a manufacturer goes to the trouble of supporting their products this way, it shows that they really believe in what’s being sold.

    I used stacker 3 xplc to improve my energy at work. I thought everything was ok at first but after a year of one pill a day it affected my kidneys. I read the label and found meny warnings about my symptoms. I have no family history of kidney stones but I did develop a 13 mm kidney stone during the use of this product. I wish I would have been more aware of what harm stacker products can do yo my body. No stars only pain and regret.

    Stackers are awesome!! Some people may be allergic to them and that is unfortunate, but still not a reason to not recommend them because obviously not everyone is going to have an allergic reaction. And the two MAIN things you need to know before taking this product is to drink plenty of water and get moving!!! Do not take this and then sit around all day because it will make you feel crappy. If you are up and moving you feel just fine! Love it love it love it (:

    Trying the S3 XPLC, Been on it for less than a week. I have tried S2 before and did not really notice any weight decrease, but no jitter or negative impact on me. I have also tried the prescribed Phentermine, but that gives me bad dreams, and makes me edgy, short tempered so I stoppped it. It does provide great energy but that another story.

    For taking the stackers, if it is your first time around, I do recommend eating first. For this time, I needed extra energy to get pass the afternoons at work, it does provide good energy for about 2-3 hours, but then after you get so hungry. I just supplement it with eating fruits or drinking more water. So far so good. I have 3 of these bottles and hope to help me supplement weightloss plan with my strict diet – no rice & no red meat + more fruits and veggies.

    does stacker 3 give irregular periods?

    Hi. I would NEVER recommend any stacker product. I had the same reactions as Loraine but worse! It’s been 5 days since my serious allergic reaction and I can still feel it! Major jitters and shakiness,red eyes, chest, arms ears, I couldn’t talk straight, my food doesn’t taste the same anymore, I also had major increased saliva. It was my worst experience ever in my 41 years of life. I am pissed.Also, be careful if you are on any prescription med because there is nothing that suggests anything about interactions with meds. I am on Lyrica, amatript, and tramadol for fibro. THEE biggest mistake. For everyone… PLEASE INVESTIGATE FIRST!



    it made me sick to my stomach. i thought i was gonna die. couldnt function. my stomach is still messed up! class action lawsuit??



    Why would you sue? You take the product at your own risk. Most diet pills you take make you feel sick if you do not eat first. You will not win anything. That’s like drinking milk and then you break a bone and sue them because you said it didn’t make your bones stronger. You are just sue happy and the first time things don’t go your way you want to sue. Good luck though.

    My son bought these and didn’t like them. My best friend is getting married and I needed to lost weight. I took two just today (08/22/14)for the next 8 hours I couldn’t hold my head up for if I did I would feel so sick and dizzy body hurt so bad I would get this over whelming sick feeling at first I thought I had gotten food poising then it hit me I was (at 55 experiencing high blood pressure and it one that I don’t want to ever experience this pill changed my life! People if you are over 50 please make sure that you can take these pills just ask your doctor! Please don’t be like me and just take them! I have a whole new outlook on people who have high blood pressure! The only good thing that came out of this experience! I will be able to know the early signs of high blood pressure.

    I first used Stacker 3 for weight loss, and I did not notice any weight loss, but I did get a lot of energy. I now use it to pull al nighters for school. I think it really helps. I also lose the hunger for like 2-4 hours and then I get very hungry afterwards. I am just very satisfied with the amount of energy it gives me to stay awake and alert, and to workout even longer and more intensive. I think this may be better than the 5 Hour Power Energy shot.

    I take Stacker 3 to help increase the results of exercise and to get a little extra energy. If I take it without eating about 20 mins after I do get jittery, but if I do something active like a workout or cleaning the house or playing with the kids I do not get jittery. I like them just for the extra energy but apparently have not taken them long enough (less than 1 week) to see weight loss results. Overall, thumbs up!

    a coworker gave me 1 and it made me very very jittery. increased my heart rate and breathing to the point where I had to sit and just breathe for a minute. made me very cold and have the shakes, increase saliva, a runny nose. not really sure if I would try it again it was not really worth it.

    You have to have food on your stomach, drink plenty of water and liquids, and you have to take it when you are moving around, cooking, cleaning, dancing, working, running, walking just stay busy.. Drink! Drink! Drink! Your urine will let you know if you drinking enough water because if it’s yellow and not almost clear you are not drinking enough water and fluids.
