Silly Rabbit, trick are for kids
In general, I feel that this product works. I have taken it for over a year now and I have lost inches. I was at 299 lbs and now done to 235 lbs. I work out seven days a week running 6 to 8 miles a day. I truly feel that this product provides the energy and makes you wanna move.

Great Weight Loss!
I have taken Hydroxycut 3 seperate times. The original Hydroxycut was great, but then I bought a bottle of Hydroxycut Hardcore and saw my weight drop and my body tone perfectly. At 6'1"-205 lbs and 10 lbs lighter I definitely owe it to HH.

Works with Side Effects
I agree with some of the other reviews. You have to find out what your tolerance is. I started with one pill once daily, and it worked well. Then, I upped it to two pills and I got kinda jumpy and my pulse raced a bit. I stayed with 2 and have been able to tolerate it, but I can't take more than the two pills once a day. I have lost 13 pounds and 8 inches. I think it has worked, but like everyone says, exercising with the pill is a must. I used to take Phentermine, and the effects would last me over 24 hours and I had such a problem with insomnia. With HH I haven't had that issue as long as I avoid taking it before bed.

Wondering wheter to take
I am a 16 year old guy, nearing 17. I am around 10-20 lbs overweight. I used to be around 40 lbs. I have lost quite a bit but it seems like I just stopped losing weight. So I decided to order some hydroxycut. I am little afraid of the side effects I have been hearing especially because I am only 16. Any tips out there on how to avoid headaches, increased blood pressure, and heart rate?

Thanks in advance.

Great fat burner!
Although sceptical about many products touting themselves as fat burners, this product did deliver. The main thing you need to do is educate yourself and READ the label for proper use. Minimum 6-8 weeks and a PROPER diet and exercise plan. It's not a magic pill that people are desperate for. You do need to put forth the effort. For me it was worth it, and I dropped 25 lbs. after 10 wks. Just my two cents.

LOSING WEIGHT FAST AND LOVING IT!!!!!
Well its been exactly 15 days since I've started this product. And its exactly what I needed to jump start my weight loss. I wrote a review 2 weeks earlier. I have lost over 15 pounds. And most of it has come off my stomach, thighs, and butt. It works great! Started with a much smaller dosage than recommended. I tried taking 2 pills two times in one day and got very sick. My blood pressure and heart beat went up dramatically. I almost called 911. Be careful using this product. Find out your tolerance first. I would recommend not just taking 1 pill a day for a couple of days till your body adjust. You cannot rush weight loss. The full dose would probably give me a heart attack. This is how I've dropped major weight. Take a pill right when I wake up. Eat my breakfast. Wait about an hour and half. Pop a second pill. Wait 30 minutes and then start my cardio work out. You have to do cardio or the pill is not very effective. I was lifting weights the first week and lost small amounts of weight. Now, I jog at 5mph for about 45-60 minutes. And the weight is just flying off!!! You got to eat right. No fast food, no fatty foods. Try to cut back on the salt also. Salt makes you retain water, and you might feel bloated while on HH. Just a sensible diet. Nothing extreme. I still eat fine. Just cut down on the calorie intake a little bit. HH does supress your appetite which has helped me greatly. I used to eat way too much at night. At about 3-4 pm I pop the 3rd pill and then might lift some weights if I feel like it. Boy this product has really started to change my body. You must drink plenty of water while on it! I drink almost a gallon of ice water a day! Just remember, HH is not a miracle pill. You got to exercise while using the product and give it some time. I'll repost in another 2-3 weeks. Good luck everyone! Remember, you can reach your weight loss goals if you try hard. Never stop trying!

Very Pleased
I have been taking HH for around a year and a half now so I can probably tell you anything you need to know about it.

You must eat when you take it or your stomach will get upset. I never personally got any headaches or nausea. It gives so much energy it is amazing. The recommended dosage is 3 pills 2x a day; this is way too much! I only take 2 pills 30 mins. to an hour before I lift and it works perfectly. i lift and run 5 days a week; I am 5'6 and used to be 175 and now I'm about 150 and feel great. This product really gives you so much energy to influence you to work harder at the gym and you will see the results.

Some negatives: It really helps with appetite and energy, but when I don't take it, I feel like it is very hard for me to control this appetite and I sometime binge eat. Sometimes if I go to the gym and I haven't taken HH I feel less motivated, I'm not sure if this mental or not.

1 question. I am in college, and I have noticed that if i drink (alcohol) on a day i take HH,i break out in rashes and feel extremely hot (in temperature). Has anyone else experienced this problem?

Hydroxycut Hardcore works but with some effects for me
Well I started on Hydroxycut Hardcore three weeks ago, initially on one pill a day for about 3-4 days and then moving to 2 pills and in the third week to about three pills. This is usually in the morning, and when i started 2 pills i used it just before workout in the evening.

The results were good.. went from 175lbs to 160lbs that is a lot.. :) happy about that.. since i could see noticeable difference in my stomach region.. So it does work..

Now the sideffects.. i told myself i would stop if any side effect pops up.. the pill definately did not affect my appetite.. nor did deprive me of sleep. I stopped after the third week because i got these incredible amount of burping.. like every minute.. that was it for me.. did some research on the net and found out that some people with too much caffeine intake could end up burping. stopping it definately helped.

So the next time i might go and get myself something caffeine free. My friend has been trying it, and he says he doesn't have a problem.. his fat % has gone from 17 to 12% and now he has got back his 6 packs.. so I would mostly do this again.. best thing take some protein shakes along with this.. probaly u get better results.. Will let you guys know if it works out for me and i get my 6 packs..

day 1- it works, but is it worth it??.. probably
I've been doing a 12 week fitness challenge with work and am on week 7 with some results but not as much as I had hoped for. Im 6'4. 243 but Im not concerned with losing weight as much as I wanted to tone up. I looked to HH to speed things along so today I started and took 2 pills about 30 mins after eating and 45 mins before workout.
I've been stuck at 244 for 10 days now but even after eating a big breakfast this morning and no #2 after (not to be too graphic- but)and I stepped on the scale before my workout and I was down to 243 and am still at that tonight.
I've never had energy like that for a workout before. I've been doing alot of rowing and normally I do 5000m on there in about 26/27 mins but today I didnt take 1 break (vs regular 2) and was done in 21.30
I had to work right after that and I wasnt intending on the side effects to be so apparent but I was jittery and somewhat lightheaded.
I think I'll do it for 3 weeks and see how it goes- I dont see myself being able to ever push it to 3 pills 2x a day.. I think I'd feel like I was going to die.

enrgy to burn
I'm 22, weigh 72kgs, 185cm tall. have been working as a labourer for 2 months, have been taking creatine and protein, as well as q10. have experienced wonderful results, however my stomach still was not as ripped as i wanted. i have been taking Hydroxycut hardcore for just over a week now. i eat 5 meals a day, granted sometimes its a force feed now, and at least two doses of protein and creatine, depending on how hard work has been. the focus i get with hh, as well as the energy makes heavy work much more enjoyable. the caffeine was a bit of a shock as i quickly moved up to the 3x2 dose, going over this has resulted in fatigue the next day. i'm impressed with this product, visually, i have noticed ab definition developing. as i don't really have weight i want to lose, as i'm also currently putting on muscle i don't intend to use this product for an extended period, however 3 week treatments every 2-3 months should be sufficient. i eat well, except for at night, very unhealthily, ice cream etc. my opinion, if you are motivated to exercised hard, and you take this product you will lose weight, quickly.

Mixed Reveiws
For this product I have seen many results good and bad. After reading what all the chemicals actually do, it explained my reaction to it. I am a 32 year old male, 220lbs in the beginning, 210lbs after 30 days of working out and this stuff. I work out 5-6 days a week. For me, I took two pills 30-60 min prior to w/o. I have to eat something small with it to keep my stomach settled. I warm up 15 min on a treadmill then lift for 1-3 hours. This product did increase my energy for the duration of my w/o. But, you MUST DRINK ALOT OF WATER! I have always had a belly no matter how much I run, this has helped to cure that problem, I still have a little of that annoying belly fat but I am hoping that another month will complete the task. I have noticed more definition and size, part of that I have to give credit to the protien (syntha-6). I have lost 10 pounds and feel better throughout the day and have more energy. Other reveiws are correct in saying you will be nervous at rest or if you have nothing to do, thus the reason I only take it before my workout. If I take the full dose, my chest hurts also and feels like my heart will explode. I have noticed improved memory, some of my forgetfulness has gone. I can recall directions and task much better now. Cycling of this stuff is a rough task, drink alot of coffee to help off set the headaches you are going to get. Overall I think it has been a good product for me if I don't over do it.

hh
It seemed to work for the first month and then the effects wore off quite quickly. I can work out a little longer, but for the price i would say try something else. it seems your body gets used to it to quickly and after the first month I didn't feel any different whether I took it or not.

Just Started HH
I have been working out for the last six weeks before even trying HH. I am 6'2 and about 230 pounds. My previous weight three years ago was 185. Looked really good at that weight. Used to be able to drop weight quickly and pretty easy just working out hard 5 days a week. I am 28 years old right now. Guess my metabolism has slowed down. I lift weights and jog monday, wednesday, and friday. On tuesday, and thursday I hit the punching bag for about 45 minutes with ab work. Been losing weight, but its been really slow. And its been tough reducing my belly. Started HH two days ago. Followed the instructions. It is making me a bit jittery and hyper. Feels like I am constantly buzzed. My workouts have improved greatly. And have already lost 4 pounds. Its early so I won't know the full results yet. But, I am really excited about this product. Let you know full results in about 3 or 4 weeks.

Quick Fix
HH is a great product. I've used it in 2 ways due to sheer laziness and quite the lack of will. For the first month, I worked out on HH and used the recomended dose (3pills 2x per day) and lost 10 lbs in a week, so i cut it down to 2 pills 2x per day and have been steadily losing about 2-3 lbs per week since. On month 2 I quit going to the gym and ate like crap. I STILL lose 1-2 lbs per week. I dont care if it aint right, I'm lazy as hell.

Question about HH
I'm a 19 year old male, 5"11 and I weigh roughly 170 pounds. I workout 6 days a week, upper body monday, wednesday, and friday, and then lower body tuesday, thursday, and saturday. I run almost everyday and do about 30 minutes of cardio. I also take protein, but thats it. I am gaining muscle, and have gotten bigger, but I want to get toned, especially in my stomach. Will HH help me gain muscle, and tone myself, or will I just lose it? I am considering trying HH so I will post again when I hopefullysee results.

its been two weeks
Well I'm 26 years old 5'7 about 183 I started working out about three years ago( four to five times a week over a hour of weight trianing and 40 mins of cardio) where I started off weighting 220, but over the last seven months or so I have hit a wall I can't seem to get pass that stomach fat. So I begin to take hh the first day of taking one pill twice a day (one 6am then 3.30pm right before I workout) the first day I felt a little funny and space out but after that I was fine. I use to run three miles and get tired now I can run 5 miles and still have enegry. When I moved up to two pills a day the same thing happen the first day I was kind of space out but now I'm fine. In two weeks my stomach has seem to already shrunk fromm visually looking n a mirror and now I have abs starting to stick out, even this morning I put on a pair of pants that would fit good but now they won't stay up so I proably have lost like a inch and a half n my waist I don't weight myself anymore cause wight lost is not my goal pretty much toning and getting cut long as it looks good I could care less about the weight. Just remeber to drank plenty of water and u should be fine.

so far so good
ive been taking HH for a week now. i dont take the recommended dosage. i think that would kill me because one pill gives me lots of energy. im 5'4 122 lbs. i take one pill in the morning and one in the afternoon. ive noticed that i can workout much longer before i get tired. also my appetite has decreased lots. im a big eater and now i eat three small meals a day. my problem area is my stomach and im basically taknig hh to try to get rid of a layer of fat that hasnt budged since i started exercising 9 months ago. i already notice my stomach feeling tighter. hopefully it keeps working and doesnt make me keal over or anything.

Great results
It's amaxing, I got great results!!!!I started using it last months. It's been probably 5 weeks now. It's not cheap, I use 3 pills first thing in the morning 30 min before breakfast, then 3 pills before my workout. If I dont workout, I take 3 pills b4 lunch. Plus CLA Tonalin twice a day and one multivitamin. I lost more than 10 lb. I have a lot of energy, when I workout (3 times a week) I perform better. I show more defined muscles, and feel great...love it! Oh...one thing, I'm getting headaches more often and I have to eat every 3 hours, small snucks between meals, otherwise my stomach hurts. Plus...one advice to everyone, try to eat often, high protein, low carbs food, drink a lot of water even if you dont feel like it.

Hydroxycut Hardcore
I definitely notcied fat loss within the first couple of days, especially around my stomach. I found if you don't exercise while taking them you get really restless and kinda agitated. I experienced some stomach pains and headaches at first. But altogether they're pretty good, they definitely keep the fat off. The key is exercise. You'll feel better and you'll get faster results.

Going to buy another bottle
I have decided the best way to take the pills is 2 around 8am, 2 30min. before lunch, and 2 either 30min. before I go to the gym or eat dinner. The side affects have worn off and even when I forget to take the pills or dont have them with me my hunger is not the same. I don't have to eat much to feel satisfied, I think that is what has helped the most. I will keep you posted till the wedding to let you know how happy I am with my results.

Extreme Cheddar!
It makes me want to go freakin' nuts, but I love it. Dosage is two pills twice daily; the individual at GNC advised me to keep with it throughout an entire cycle. He said that the three pills twice daily is a little much for most people. I would agree because when I took the first two pills, I felt like I needed to run 100 miles to lose my new found energy. I can feel the fat melting off.

Women Beware
I have been taking Hydroxycut Hardcore for almost 2 weeks now. I started my period and was bleeding excessivly. Enough for the Doctor to tell me to go to the ER. Come to find out, Hydroxycut has an ingredient in it that is similar to aspirin and it thins your blood causing you to bleed more. The ER doctor was quite surprised at this as was I. I will still take the Hydroxycut as it is really helping but I now know to take a break around period time.

GOOD FOR SOME - NOT FOR OTHERS . . .
In response to "Justin from Manalapan" as well as my opinion and findings of HH - Just like anything else you take or do, including exercise routines, you must introduce HH to your body SLOWLY. If you are ignorant about products and dump a mouthful (or double up) looking for a quick fix or miracle, anything assuredly will be DANGEROUS! I found it just fine and extremely HELPFUL to shrink belly, butt and thigh fat while light working out at least a few times a week, and eating small, normal meals. I think it is great for a helper.
