It is really very effective,makes me sweat even when I am inactive. Just started using it over a week now and I already feel good.

Very Awsome product!!! ive lost 7 pounds in one week. taking this. Some was water weight but probably 4-5 lbs of actual fat tho.. Last thursday i weighed 217 now i stepped on the scale weighing 210. Noticed less stomach sticking out. Im about 6'3" so its not that noticable but i know though

This one is crazy! Made me loose 5 kg of fat at 1 month. I could've lost more, but i didn't push myself to the limit!

the first couple days i was a little jittery. but then i adjusted and its been pretty good! ive been losing a steady amount of weight and so has my husband. two thumbs up :)

Well just on my 2nd day. Didn't really notice the appetite suppressant. Think my energy levels are up a little as I didn't feel too tired after lunch as I normally do. Will update later

Great Fat Burner lost 7 Pounds In 2 Weeks And It Gives You Lots Of Energy. Very Important Diet Good Results Till Now.

I I dislike this product. Instead inhibits appetite I feel a monstrous hunger. I feel a slight dizziness and weakness after 1-2 hours of daily dose. Bad energy ... Older Oxylite was very good. I'll try the new formula and Lipo6 Black UC nevermore.

I've used Nutrex fat burning products before and have never been disappointed until now. I've been using the Black ultra concentrate for a few weeks now and am pretty bummed. It does not give me the energy and results that i've had in the past with previous products, and actually makes me feel nauseous most of the day. I will not be buying this again.

I used this for a month and a half..Start off taking 1 pill as soon as you wake up in the morning on a empty stomach then 20-30 mins later, eat breakfast..After your body gets used to it amp up the dosage to 2 a day. 1 in the am and another 1, 5-6 hours later. Always remember to drink PLENTY of water when taking this!! The first day I took it, I could feel it working and kicking in my stomach. With good diet and monday-saturday weight training and cardio I lost 10-15lbs. I was 175lbs on and off but this helped me get down to160ish. But after 2 1/2-3 weeks using it with 2 pills a day I didn't feel it anymore so I'm guessing my body got used to it..But overall It is a good supplement, and I would recommend it to my piers! I give it 8/10

this supp gave me crazy energy to kill my p90x workouts. hunger suppression isn't big but the energy pushed me through that 2:30pm nap time feeling. My reason for the 10 is because energy and the 3/4 of an inch I dropped this past week

Muito bom esse termo, tomava um de manhã antes o café da manhã, deu um up no metabolismo!

Very weak as a stimulant and for hunger suppresion.No thermogenic feeling at all even when being active throughout the day.Hunger suppresion is hardly noticeable.Price is not ridiculous but is on the higher side (over $35). Side notes-Older Lipo 6 formulas worked great for me.Im not a caffine(coffee,soda,etc) drinker.Im over 35yo and have a active job

Overall this product does what it is supposed to. I never got the jitters or heat flashes, which is good because I can't be sweating like a pig in class. It does suppress my appetite quite well. When I fist started taking it I couldn't even finish a 6'' sub from Subway (I used to be able to eat a footlong and still be hungry). I won't say that the fat will melt away because it won't. Any weight loss supplement is meant to "supplement" a healthy diet and exercise plan (who woulda thunk it). But great product in my mind.

c4 and consumed the east, the lipo 6 is much more effective, also requires fewer doses.

Loved it worked great. Lost like 10 lbs in the first few weeks. Had extra energy for my workouts and def curbed my appetite. I didn't give it a 10 bc I stopped taking t and immediately gained the weight back :( I tried hyper shred and that did absolutely nothing for me.

lipo6 black ultra and oxy elite are the 2 best!! the oters are not good
