Adipex-P (phentermine) "I started taking Adipex on July 15, and I must say I have definitely seen a difference in my eating habits and it's only been 3 days! Amazing! I was 127lbs in 2012 and somewhere along the line I lost the will to work out and stay fit. Needless to say I gained about 35lbs since then so I am giving Adipex a try and it's doing wonders for my appetite! I experienced dry mouth the first day and that's the only side affect I have had. I eat a yogurt for lunch and dinner is 2 turkey sandwiches on wheat bread, and I drink 2-3 bottles of water a day. Eating right and exercise are key to helping drop weight quicker! Once you stop taking the pill you must maintain good eating habits along with exercise or the weight will come back plus more!"

"I’m 62 and a Veteran. I have always been active. I started slowing down a bit, and gained some weight. I’m Diabetic and have tried to loose weight. I’m 5ft 8 and weighed 240 lbs. I went on a 1200 calorie diet for 3 months and loss 10 lbs. I leveled out. Went to see my PCP for some help. He put me on Phentermine 30mgs per day . Wow , in 2 months I have lost 24 lbs and eat like a bird. I have a salad and I am full for the day. I still walk and stay busy. I am retired because I am disabled. My desire for food is almost zero. I feel much better, my blood sugar is way down. You have to drink lots of water on this medication. Dry mouth is always there. I have to keep going and I plan too. For my Family. God Bless."

Adipex-P (phentermine) "I've been taking Adipex capsules for 1 week now and I am down 11 pounds. I don't exercise. The pill just makes me not want to eat. I have to make myself eat. I also have severe dry mouth, so I drink water way more now. The only other side effect I have is heart flutters. But I can handle that, because it happened to me before I was on Adipex."

Adipex-P (phentermine) "I just started taking Adipex. I think so far it's helping me a ton, I'm on 1000 calorie diet plus Adipex. I'm working out every day, this is my 5th day and I already lost 6 pounds. Adipex seems to be helping me from over eating, it seems to be helping me curb my cravings. I have no craving for sweets of any kind, so far so good."

Adipex-P (phentermine) "I am 20 years old and I have always had problems with weight loss since I was in middle school. I went to the doctor and was prescribed Adipex. I have been on a low carb diet and I have been on Adipex for 9 days now and have lost 6 pounds so far. I am very happy with the results right now and I'm hoping to keep at it and try to reach my goal weight! I am 5'4 and before I started the diet I weighed in at 192lbs and so far I am down to 186lbs. My goal weight is 145 to 150lbs!"

"While this medication may seem useful & effective in the beginning, be careful. I've been taking this medication off & on for approx 10 years. I've found the longer I'm on the medication, the more addicted (mentally & physically) I am to it. I love the energetic, invincible feeling that it gives me in the beginning, however, I've found that I am more irritable & moody now too. I have gotten to the point where I feel I can't function without it, although it's lost its suppressant effect."

Adipex-P (phentermine) "I started taking Adipex in Sept and went in on Dec 7th for my three month check in and I lost 38 pounds. I am 5' 8" and began weighing in at 259 and am now down to 221 and this is without including exercise. Walking is part of my daily routine, I walk a lot throughout the day as I'm running between classes and then to go to work. I did experience some side effects the first week like being light headed, dizziness and a dry mouth. But I use that to increase my water intake. My doctor actually recommended I only take it about 5 days a week so that my body doesn't become so used to it and that's what I have been doing. So far, so good and I can't wait to continue losing weight."

Fastin (phentermine) "I just started using Fastin and I like it better than other diet pills I've tried such as Hydroxycut because it doesn't make me feel sick/ nauseous. BUT it definitely makes my heart rate skyrocket, so for the first couple days I would only take half a pill at a time. A full pill makes my hands tremble and I can hear my pulse in my brain."

Fastin (phentermine) "I’ve been taking Fastin for about a year. And took it for a few months the year before. I love this medication. It helps me not be so tired. I take it as soon as I wake up and I’m good for the rest of the day. When first taking it make sure you eat a little something otherwise it will make you feel sick. It does make your heart rate go up. I don’t mind it because I know you have to get your heart pumping to lose weight. Went from a large 16-17 to a 11-12. 205lbs to 160lbs in past year and I’m only 5ft 2in. (I have large hips). It helps me have energy that I haven’t had since I was a teenager. And I only take one tablet in the morning. This medication is a blessing to me!"

Adipex-P (phentermine) "Teva changed adipex formula (no blue dots anymore) and although they say that was the only change, these are worthless. Not only did the cost go up, but they are ineffective. I spent $600 for 90 supply!!! I have to take 3 whole pills to get any effect whereas the pills with blue dots 1 to 1.5 was sufficient. All it does is make my face super hot and makes me super tired. I have called and reported it to teva also, but nothing is being done. Not ok to do this to consumers and take advantage like this."

I'm so happy with my result, my goal is to go down to 155 lb or around... I’m 5’6”"

Adipex-P (phentermine) "This drug is extremely effective. If you're not losing a lot of weight very fast like the more amazing stories you read, you are not taking full advantage of it. It will give you an amazing kick start to a new life that will be very difficult to maintain and that you must be very committed to or you need not bother -- because the weight will come back otherwise. Friends & I lost 20 lbs per month, so 6 months is the max length of time you should be using it. After you are finished with it, the real you will reappear and you will again have to fight all your original demons; hunger pangs, portion control, will power, laziness. If you can't do that, don't bother to set yourself up for yet another diet failure and heartbreak. OK 2B Hungry :)"

Adipex-P (phentermine) "I was on adipex in 2010. I started out at 272 lbs. I was amazed at how much weight I lost every week. I had to buy new pants, jeans..etc every week. I averaged 8-12 lbs lost per week. I lost 126lbs in just under 5 months. I was very active, exercised everyday and didn't have the craving for food. I did find that not eating lead to headaches and mood changes. You have to eat!!"

"I started phentermine right before thanksgiving. I am 5"2' and starting weight was 184lbs. It made me not hungry at all. I constantly drank water and ate very lightly. No insomnia first month. I lost 17 pounds. Second month I had to take 3 days off because of the insomnia. If I feel I can't sleep I will skip a day or two. Still only drinking water and eating lightly. No exercise at all and today I weigh 156lbs. Total loss of 28lbs in two months. This month I plan to add exercise to drop more weight. Love Phentermine!"

"I started taking 37.5 mg at the end of June 2023 and it's now the end of December 2023. I have lost a total of 53 pounds in 6 months. I have cut out carbs, sugar, and stuck to water (trying not to drink my calories), all while staying in a calorie deficit. I also have not worked out one day this whole time. Don't get me wrong, I am human and have my days where I have a cheat meal or a piece of candy, but I definitely limit myself to this. Overall, I highly recommend this medication as a way to help you change your lifestyle. Take this as early in the morning as possible as it gives you a lot of energy and taking too much may keep you up at night. I have experienced dry mouth with it, but it has gotten better the longer I take it. On the plus side, the dry mouth makes you drink more water and chewing gum helps. I would say to give this medication a fair two-month trial to see if it's a good option for you."

"Hello. I'm a 28 year old female standing 5'3". I went to my doctor on 7/31/14 and was prescribed phentermine 37.5. At the office I weighed in at 275 lbs.! I started taking the medication on 8/1/14 (half a pill to see how it would effect my heart rate. I have hypertension). On 8/2/14 I weighed myself and the scale read 269.6. I only took half a pill that day, too. This morning, 8/3/14, I weighed in at 265 on the nose! I've been overweight since the age of three and remember being on diet pills at the age of nine. I've tried it alI. As an emotional eater who needed a miracle, all I can say is thank God."

Adipex-P (phentermine) "I was put back on Wellbutrin back in February 09' and I started at 223 lbs. A month later I went back for a checkup and lost 6 lbs on my own. I then asked about Adipex. The Doctor put me on it in March 09'. I lost 19 lbs the first month. It is now August 09' and I am down to 159 lbs --- below my goal weight of 165 lbs!! This is the last month I will be taking Adipex but I will continue my low carb, no sugar diet. I also exercise 2-3 times a week at the gym for about 75 minutes. It has really helped me change my lifestyle. There is no magic pill out there! You really have to be dedicated and be willing to work hard."

Adipex-P (phentermine) "I was prescribed Adipex on Nov 10, 2014. I weighed 155 pounds. To some that might not seem like a lot, but it was to me. I had tried working out and eating right and nothing was helping. Today, Dec 22 I weighed 135. I have steadily lost weight since starting it. I skip some days and still feel energetic and not as hungry. The first week on Adipex, I had the worst dry mouth. I couldn't drink enough water. I still an pretty thirsty but it's manageable. Drinking water helps the medicine work better. I have also changed my eating habits to use when the pills are up. The first night I didn't sleep, but now I can go to bed no problem. This medication isn't a quick fix, it simply is helping you make life style changes to keep weight off."

Adipex-P (phentermine) "I re-started Adepex today. Full dose. I had amazing results 2 years ago. Went off it, but gained 40 lbs back. Unlike some user reviews, I can tell you the weight gain was NOT a result of quitting Adipex. It was poor choices in diet and lack of exercise. I got lazy. But NOT because I quit taking Adipex. I started today because I need help. It is a potent drug. And it will make you not want to eat. EAT ANYWAY. When you don't, you WILL experience mood swings and hostility. The purpose of this drug is to HELP you make better food choices and to get into a good exercise routine. Drink LOTS of water and EAT every three hours. Do some research BEFORE taking this drug. It can be EXTREMELY beneficial if you use it the right way. Good luck all."

Adipex-P (phentermine) "Started Adipex late October now it is in the middle of December I have lost 20 pounds. The pill literally cut my appetite and I drank water. No sweets, breads. I really didn’t excercise, but house work, working and being a full time Mom and Wife,I guess you can say that’s where it came from.The only side effects I had was dry mouth and Insomnia nothing too bad. Oh and yes I could have lost more weight but I skipped some days taking the pill"

"I'm a 18 year old female, my entire life I've always been overweight and I wasn't able to lose it, it didn't bother me until I gained 40 pounds in less than a year due to being on birth control. I went from 175 lbs to 215, that's when being overweight caught up to me. I wasn't noticing how much the way I looked changed. Until I went clothes shopping and I couldn't fit into a size 16. That was when I went to my doctor and he recommended Phentermine, It has been almost 3 months and so far I've seen nothing but positive results, I lost 31 ponds so far and still going! I bought a size 13 mini skirt, it was too wide! I haven't fit into a size 11 since I was 15. I strongly recommend it, because of it I smile every time I look in the mirror now."
