eric: Black peper and caffeine, give me a break!!!

laura: Is this GNC X12 made by GNC? I usually trust them….

eagle_Eyez: I thought this GNC X12 was just cheap junk. GNC is obviously going downhill. all this did was provide me with basic caffein energy.

Libby: It definitely did something, I felt pretty energized while taknig GNc X12, espcially after workouts. THe buzz lasted longer. But the caffeine was causing me to wake up several times during the night so I stopped taking it after 2.5 weeks.

Evelyn: this is supposed to make you burn 12 times the calories when you exercise? with a little help from cayenne and coffee? really? who knew? puhleeeeeze!

Sarah: I just wasted $45 on this stuff. Oh well, next time I’ll read the reviews first!

Tessa: GNC X12 (which sounds like a robot btw) gave just a slight buzz, but no real results for weight loss metbaolism or apptetite control. I hope GNC gets back on the ball, this sucks.

Monique: Why would coffee make you lose more calories? Does this fall into “if you eat celery the chewing will make you lose more than the calories you’re taking in” category? Just because my heart’s beating faster doesn’t mean I’m losing weight, does it? Hmmm.

Violet: The only exercise I can really handle right now is walking and I really didn’t care for the way my heart ws racing after taking just one of these pills (GNC x12). Will they take it back do you think?

stef: When i take the GNC x12 too late in the day it keeps me up at night. I can’t afford to have that. Plus it doesn’t help with my appetite at all, which tends to be raging at about 4pm or so.

dave: This product is weird, they say that GNC X12 helps you burn “12 times more caloires” but then they say it makes you burn “278 more calories.” how can they come up with that number when they don’t know how many calories you usualy burn? Is 12 times as many calories always 278? It seems to me they are messing around with these numbers and its all a bunch of abritrary bs. ESPECIALY since it is nothing but pepper and caffeine!

AL: Took GNC X12 for a couple a months but was getitng tired of it, I reached a plateau after the first month and was not able to lose more than the 8 lbs I’d lost initally. Nuphedrine has been a better product for me, been using for 3 months now and lost 21 lbs.

Barry: I did not like X12 much. Didn’t have side effects but it didn’t work for me either.

Rosina: Those numbers also confused me but it all sounded good anyway, more calories is more calories. Trouble was, I was so damn hunger, I ate more, usually went for carbs too so, I never lost any weihgt.

Valerie: yeah, i felt more hungry too!!! what’s up with that???I didn’t even finish the bottle of GNC X12. I don’t need an “appetite enhancer” thank you very much!

homerSIMPSON: nuphedrine, is that the one with advantra z, i heard some gys at the gym talking about it i think but they were all muscle-y so i didn’t no it was for weight loss?

Diego: I am not a huge fan of X12 but I do credit this GNC product with getting me back in the mindset for fitness and watching how I eat. I don’t have to do much to lose weight I remembered.

jolly_j12: stuff made my face all red and hot, whats up with that? i felt sweaty before i even worked out from the gnc x12 is it normal?

JOE: CAFFEINE IS NOT A FAT BURNER!!!

Karmann Ghia: This GNC X12 is the shittiest GNC product i’ve ever tried they are def. starting to decline in quality

Miles: Would never make it to my sports club after work if i didnt have caffeine. Coffee upsets my stomach from all the acid, GNCX12 is just fine for me, I work out so hard my sleep is not effected either.

jonathan: HEY – SEEMS TO BE SOME CONFUSION HERE. GNC X12 DOES NOT HAVE ADVANTRA Z, IT JUST HAS BLACK PEPPER AND CAFFEINE. THE OTHER PRODUCT MENTIONED ABOVE, NUPHEDRINE, APPARENTLY DOES HAVE IT. OK?

lora: Really was not as strong as I expected, I actually didn’t feel anything at all from these GNC X12 pills. MAybe I’m just too used to caffeine? I was disappointed in it, waste of time and hope.

Therese: well, the master cleanse has cayenne in it so maybe there is something to this…?maybe?

RexNeffects: How much do just straight up caffeine pills cost? THat don’t clim to be diet pills? Maybe that’s cheaper way to get the rush. Hhaha cheaper than STARBUCKS!

MARGOT: I would not go so far to say it sucks but i don’t think its worth 40 bucks. GNC X12 helped me to stay alert for the day but also I had cravings as usual, like others mentioend. ANd I felt i could justify eating since I was already burning more with this. not a good idea. Nothing gained, but nothing lost either.

ginger_spice22: this made me half to peee all the time. thumbs downs

Marion: GNCX12 – I wish I would have read this block before I bought it. I just took second pill this morning and my heart beat was raising so much that I thought I was going to get heart attack. I was swetting and rolling around in bed… Very scary.

Anonymous: I really wanted GNCX12 to work, but the stomach pain was too harsh to continue use. Other side effects: jitters, sweats, diarrhea.

Mitze: I had an allergic reaction and broke out in hives and my face got all hot and blotchy. Had to take a benadryl immediately to counteract the effects. Now afraid to use the GNC X12 product.

krista: wow..have yu people even tried this product because i have and in one week i have lost 7 to 8 pds ..no side effcets more energy happy and look great! this product is safe and doesnt have ingrediants like some that mess with ur whole metabolic system but it wont kill you…it is wonderfull before workouts and keeps you alert…ive tried all products and this is by far my favorite because i dont feel like im going to die

Ms. Lady: Over the last two years I have used this product on and off again. In my situation 5:6 280 it worked just fine! My first go round I lost 24pound in 3wks. Now let me say this the pill didn’t help with my eating habits (I think that’s more of a self control thing) But it did give me major energy for my workouts. I worked harder and faster using this pill so in my opinion it did exactly what I needed. And once I got into the motion of things it’s was almost hard for me to stop! But each individual is different, I gave a pill to my friend and she threw up 45mins into our workout. So you have to find whats right for you, your body and your situation. It depends on what you are looking for in a pill. when I visited the store I asked for a energy booster and that’s just what I got!

Ryan: Lost 6 lbs in the first 10 days. I will keep taking in for the next 2 months to achieve my goal. The blochy warm feeling is just a reaction to the Niacin in the pill. It’s perfectly natural and harmless. Its not HIVES!!!
