Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I would recommended this diet pill to anyone, it works great and the energy boost allows you to do your daily activities with no drained feeling after. I would advise a daily routine, sit ups, push ups, walking, etc. Of some type. I'm a mother of 2 boys, 4yr & 3 1\2 month old, my stomach has stretched a bit, I was on it after my first son and went from 176 and dropped to 125 and was only on it for 2months, the weight stayed off til my 2nd pregnancy, naturally I gained so I'm now on it again, but due to more stretching my muscles are weaker in my abdomen, if you rely solely on the pill you will loose weight and appear thinner but you will have saggy ecsess skin, you must tighten as you shrink. Chances increase due to rapid weight loss."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "Hi I’m 5 foot even and I’m at my biggest weight ever at 189lbs(I’m considered Obese)!... I just started back taking Adipex today my baby just made a year old and can’t wait to see how I do this time, back in 2010 I began taking Adipex and the first 2 weeks I lost 11lbs, and for the first month altogether I lost 30 lbs. My doctor gave me my rules while taking this medicine and to see the best results, he said plenty of water and cut the starch (rice, potatoes, little Debbie pies and etc...) and your going to loose tremendously, and I did so and I was very pleased with my results! It does work but you have to discipline your eating habits, I would do a smoothie in the morn everyday and lunch, dinner and snacks I would only do pan seared, grilled or baked meat(any meat) and I bunch of fruit and veggies try it and I promise you, you’ll be very please!.."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I usually don't give reviews but for Adipex is necessary that I share with you. I started on 3/4/14 at 215 pounds, today 4/7/14 I'm @ 198lbs. In only 33 days I've lost 17 lbs. I'm eating healthy and small portions, cause I don't get hungry.. I don't crave nor look for fast food restaurants. I've added more fruits and veggies into my menu. I'm staying away from sugar and bread. I'm thirsty all the time, water, water is my best friend. If you are reading this I was just like you 30 days ago reading and trying to find out if this would work, and my answer is "YES" it does. Just take it day by day and eat right and exercise. Will give my next update at the end of April."

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "I started Fastin 30mg from my doctor on May 19 2014. You need to change your lifestyle not just pop a pill and be done with it. Because if you don't change, the weight will return. I started at 285lbs in one month I lost 25lbs and feel great. I changed myself with habit changes and exercise. I told myself that when this weight is gone it's staying gone, so I change my lifestyle and you can do the same."

For Weight Loss (Obesity/Overweight) "I started taking 37.5 mg of phentermine - one pill am. Before taking this I had been exercising and eating right but I could not lose a pound. Since starting phentermine a week ago, I am down 5 lbs. I am so excited! I have so much energy and no appetite. I was close to 200. I also have fibromyalgia and it helps with that. I think they actually should prescribe it for fibromyalgia. I took Cymbalta in past for fibromyalgia but phentermine is so much better! I am going to hug my doctor if I reach my goal of 150. Side effects for me is dry mouth but you end up drinking more because of it so it isn’t a bad thing. I honestly feel like this maybe a miracle pill for me!!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I started Adipex-P nine months ago and I've consistently lost weight. When I weighed in at the Dr.s today, I am down 20.6lbs since last month! I've lost a total of 83lbs and was approved for my left knee replacement on Nov 18. When that heals, we do the other one. I have battled obesity my whole life- had gastroplasty (stomach stapling) back in the early 80s and I've lost and gained hundred pounds during time periods in my life and I've got hope now that there may be a light at the end of the Tunnel. When I get my knee joints in and get active I think I really might be able to get down to a decent weight and make it stick. I'd like a second chance at life, to find a wife to spend my retirement years with. Staying Positive!"

For Weight Loss (Obesity/Overweight) "This one little pill changed my life. I weighed 208lbs wearing a size 18 and had tried everything to lose weight and just couldn't. My doctor whom I was working for suggested taking phentermine and I'm so glad he did. I was losing an average of 1-2 pounds a day. I lost 65 pounds in 2 months! Now wearing a size 8. I have not taken the pill in the last year and I did not gain any weight back. The only side effect I had was dry mouth. I can handle dry mouth for the results I got from this amazing little pill that changed my life."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I started adipex on 5-23-16 exactly 4 weeks ago from today. From the first day I took it I noticed a huge difference. I lost almost all appetite, and had to force myself to eat even though I wasn't hungry. The best thing about it is when I did eat I took the time to think about what I was putting in my body and made better and healthier choices. There are times when I wanted something I knew wasn't good for me, but my will power is stronger and I turned from it. I drink only water...It helps me stay full. I also have been working out 2-3 times a week. Only side affect I've had was dry mouth the first week. I went to the doctor today and I've lost 23lbs in 4 weeks. I recommend this to anyone struggling with weight loss."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "3/19/14 Went to the Dr and asked about starting Adipex. I was extremely unhappy with myself, I stepped on a scale a few days before this and realized I weighed 250 I have never been this big I am 5'10". I started taking the medicine and walking every day at least a mile then walking has led to jogging and crunches. I still have my Sweet tooth but not like before with the medicine and willpower on 4/11/2014, I weighed in at 232. I didn't even realize I have lost that much my goal was to lose 30 lb by July 4 and I believe I will well exceed my goal!"

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "I started taking this pill when I was 218lbs and I now weight 135 lbs! I had thyroid issues too that originally caused the weight. But once managed I still had a hard time getting the weight off. This pill literally changed my life! Yes it does speed up your heart, my dr did an ekg before hand to make sure it was safe to take. But the results are beyond worth it. And if you take it with water or juice and a banana, you'll be good to go until dinner time! It took roughly 6 months tops to lose the weight, and I've maintained the weight loss for about 3 years now. I still fluctuate a little due to my thyroid. But I just start back on it if I need to lose again."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I love love love Adipex! It took me about a week to get used to all the side effects but when you realize how much weight you are losing the side effects aren't even in your mind anymore, I started taking Adipex Jan 24th 2014. Weighing 210 pounds. Today is now Feb 19th not even a month later and I now weigh 185. That is 25 pounds down in just one month. I work out (run a mile, ellipitical, 20 min abs) 5 to 6 days a week and I only eat 1000 to 1300 calories a day! This pill is amazing and everyone needs to try it, that is wanting to lose weight."

For Weight Loss (Obesity/Overweight) "5”11 and I weigh 170, yes I’m tall but this is the heaviest I’ve been and I’m not happy with it. Side effects: no sleep , lower back aches , dry mouth, made me angry which I’m never angry. Also here and there a little depressed. But I would have to snap out of it very quickly. But overall it’s a good pill to take if you have self control and you won’t get addicted to it. It gives you lotssss of energy which I like to work out in the gym or go for a jog at a park. You will lose weight quickly but you have to maintain it . I have a sweet tooth so I would eat chocolate after I lost all my weight then I would see I gained weight like 2lbs and I would work out the next day. You have to be consistent and dedicated."

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "This is my 3rd time using these pills. The first time was in 2012, I lost roughly 35 lbs. I started again about 2 months ago. I kept the weight off, for about 4 years then got too comfortable and gained weight so here I am. Along with everyone else, when I first took an entire pill I too thought I was going to die. LOL funny but not funny. I started breaking the pill in half & I had no more issues. I DO NOT recommend taking these pills on an empty stomach. Eat first, take with WATER no caffeinated beverages or juice. Drink at least 16 ounces of water with it and you more than likely will not have anymore side effects. I feel completely normal when taking the pill as mentioned above. Hope this helps!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "Adipex-P worked for me. I lost the weight and I'm keeping it off. I haven't become resistant to the medicine at all. The generic brand is different - I had a headache and dry mouth. The name brand - no problems. I'm continuing to take it under the supervision of my doctor. I have no side effects, I feel good and I'm at a good weight. I exercise and stay on a low carb/high protein diet. This medicine rescued me from the weight loss merry-go-round."

For Weight Loss (Obesity/Overweight) "Update, (I did a review on 2020-01-23) I have been taking phentermine now for 30 days. I started out at 316 pounds. As of this morning I weighed in at 295. I’ve lost 21lbs. I am 49 years old and 6” tall. I am surprisingly ecstatic over my results. As far as side effects I actually haven’t experienced any. The very first day I took the medication I did have mild increase in heart rate. I know that the medication will react differently with each individual. But so far mine has been non existent. I will check back and give update in another 30 days."

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "Fastin is an excellent dietary supplement for me. In the morning, right as I wake up, I take the little guy. The pill tastes like what I would imagine what baking soda would, but oh well, I am not sucking on it. It takes about 20-30 to give the first kick. That kick is the rush that says "I need to get moving or I need to get to the gym." The first time I took the pill I did get a little jittery and nauseous but once I started working out and drank water I started to feel fine. About an hour in I hit phase 2. Phase 2 is the spunk and mood booster. I feel awesome and amazing like I know what I am working for. Again, first day I felt a little dizzy and euphoric. Then there is phase 3 the come down. Drink water and eat a solid. I lost 100lbs."

For Weight Loss (Obesity/Overweight) "Please, for those of you who read reviews, don’t make such high expectations of yourself. I’m seeing that you weigh 200+ pounds and your goals are around or under the 150 mark which is completely understandable to want to reach. In my past, I have set such high expectations and failed miserably which made me feel even worse. I have learned that it’s so much more satisfying to reach tinier, more realistic goals in a shorter time span. Tell yourself that your first goal is 10 pounds. You’ll work hard and when it happens, you’ll be motivated for more. Set another realistic goal. Reward yourself. Not with food, but just a little something to say job well done. It works. Me - 310 to 185."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I am 5'5", and 31 yo. I have been overweight my whole life. Even as a child. At my heaviest I weighed 256lbs. I could hardly make it up and down the stairs. That is when I started taking Adipex. I am now 149lbs, and feel amazing! I know that there are side effects with every medicine, but there are also side effects to being overweight. Honestly, it is not easy to being weaned off. You have to work hard everyday, not to cave into the cravings, and keep active. It gave me the edge I needed to make that life change. Other friends that have tried using Adipex, but could no stick to the diet and exercise plan and lost little to no weight! You need to want to make the change, the pills just help."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I've taken Adipex on & off for about 14 years now. Each time it definitely works. It's the only thing that has ever worked for me. I always gain back what I've lost when I stop taking it though, but I've also had 2 back surgeries within the last 8 years that contributed. This time I'm really focusing on changing my eating habits & doing the Paleo diet with the Adipex. So far, I've lost 84 lbs. in a year!! I walk/exercise but have to take breaks when my back acts up. It's more than calorie reduction. You have to eat the right stuff along with the calorie reduction or you'll have cravings & it'll be harder to keep off once you come off it. Stay committed to drinking lots of water. That's a MAIN key. Bottom line, IT WORKS but you've got to work with it. You've got to do your part & take it serious. I've gone from a miserable 256 lbs. to 172 lbs. & I'm aiming for 150 lbs. I was 135 lbs. before I had kids, 20 yrs. ago so I'm getting close! There is hope! Patience, determination & commitment."
