Zantrex Black

I like the 12 hour energy level it gives me while having no jitters or dizziness! price I buy mine for $20.00 on sale, I take 3 a day and it last all day long, I have no trouble sleeping. I have bad allergies to food and chemicals. After reading reviews of other products I told myself why am I looking for something else? I like this product. I just started about 2 weeks ago and it agrees with my allergies and gives me energy! I'm giving it a try faithfully.

Bottom Line: Yes, I would recommend this to a friend

I took two of them and I wanted 15 minutes. I read the directions but I got really hot on my face and neck. I also got really red my arms and legs broke out into a rash. It all went away after an hour.

Bottom Line: No, I would not recommend this to a friend

I have taken this pill in the past with no problems. Today within 10 minutes I had broken out in hives, face, arms, and hands. So bad that I went to convenient care and my blood pressure was extremely high. Loaded me up with Benadryl and still 7 hours later, my arms are still red, raised, and itchy. Face and neck are better but still itchy. Start on steroids tomorrow.

Bottom Line: No, I would not recommend this to a friend

I love this product! I pave roads for a living and I take 2 in the morning and 2 mid-day and it gives me the energy I need to get through work! I also have been losing a lot of weight while gaining muscle! I absolutely love this product, and highly recommend it if you need that extra energy boost and rapid weight loss! I would give this product 100 stars if that was a thing!

Bottom Line: Yes, I would recommend this to a friend

Yes, I have experienced weight loss, which is what I wanted but...where the heck was the extreme energy boost? I'm left wandering aimlessly, wondering when this is gonna kick in. Every single time I have a tablet all I want to do is sleep. It's as though taking the tablet induces extreme fatigue. Which for me is good because I suffer from insomnia so I now take it at bedtime. But for anyone else hoping for a daytime boost, I'd say tough luck because it ain't gonna happen.

Length of Use: 3–6 months

I bought these for me and my wife. We both had no luck. Going to try to get a refund. Will give you all an update.

Bottom Line: No, I would not recommend this to a friend

I have tried just about every diet/energy pill out there and have NEVER been so afraid for my life. There is niacin in this so I expected the red/tingling skin, but 30 minutes after I told 2 capsules I was driving and had to pull over. My vision started fading and I fainted to the asphalt. My husband caught me and kept me focused not on the thought of death. My vision went black and I could only hear my husband's voice. I was sure I was going to die. I couldn't breathe and my heart was racing. After about 15 minutes and a Gatorade, coconut water, and a bottle of water I finally could see and breathe again. After about 45 minutes I was so tired and had the worst headache. This experience has changed my life; I will not be consuming any sort of workout supplements ever again.

Length of Use: Less than 3 months

Bottom Line: No, I would not recommend this to a friend

I took a recommended amount, 2 pills 15–20 minutes before I ate. Within 10 minutes my face felt flush, then my stomach started hurting, and then my skin turned a blotchy red and I felt like I was on fire! It scared me, had to take a Benadryl.

Length of Use: Less than 3 months

I took this product and my face skin burned extremely bad. I thought I was just overheated and it had nothing to do with the product, but the next time I took it, it happened again. I’m definitely not taking it anymore because of red face, burning sensation, and hives.

Length of Use: Less than 3 months

I took 1 Zantrex Black softgel dietary supplement the first day, no problem, then ate breakfast. Then I took 1 more at 6 pm, then ate dinner, then I started to itch badly in my feet and hands, etc. It lasted for 20 minutes. Then the second day, I took 1, then ate breakfast, and started itching again, the same as the first day. So since it makes me itch, I decided to take it back to the store where I got it, that’s what it says on the box.

Why do they keep selling this product if it makes people itch? They should ban this product or take the ingredient out that causes itching (Xanthine and Niacin).

Length of Use: Less than 3 months
