For Weight Loss: "I started my weight loss journey on December 28, 2015, weighing 250 at 5'4 On January 13, 2016 I started taking 30mg Phen. The first two weeks without Phen, I lost 5 pounds (3 one week, 2 the next) . I cut my calories and walked 2 miles 5 days a week, which is about 40 minutes of fast walking for me. After taking Phen I was HARDLY hungry. Before it seemed like my 1600 calories a day wasn't enough because I would wake up and go to bed hungry. After taking Phen, I would average about 700-1000 calories a day and I felt fine. I have so much more energy that I increased from 2 miles to 2.5 miles and it takes me 47 mins. In the next two weeks of taking Phen and sticking to my diet, I lost a total of 9 pounds. 5 one week, 4 the next. It works!"

For Obesity: "I started taking this medication because I was diagnosed with type II diabetes. My doctor told me if I could lose some weight I could control it better... So with changing my diet to cater to the diabetes and these pills I started losing weight quickly. I went from 207lbs to my current weight of 173lbs in just a couple months. I feel great..yeah, you'll drink more water from having dry mouth and be a little constipated off and on, but to me it's worth the side effects because now I am a controlled diabetic and have plenty of energy to actually play with my kids! I'm sure these pills aren't for everyone, but for me... They work and are continuing to work. I look and feel great!"

Adipex-P (phentermine) for Obesity: "When I started Adipex on 1/15/16 I weighed 224 lbs this is the heaviest I've ever been. My doctor said I hit a plateau. I work in a doctors office and when I went to work on 1/26/16 I weight 208 lbs! I weighed myself on 2 other scales because I couldn't believe it. I wasn't hungry at all but I knew my body needed nutrients so I have been having protein shakes. I drank 1 in the morning and one in the evening and I took a multivitamin everyday as well. I have literally lost 16lbs in 2 weeks. Excited to see what I weigh at the end of the month..."

For Weight Loss: "My first experience with Phen was in 2013. I lost 72lbs. I don't accredit it all to that though. But it REALLY helped. The side effects were pretty bad. I had horrible mood swings, my chest hurt and I had to force myself to eat...really! I kept it off. But I also changed everything about the way I ate. I only eat fresh veges.NO CANNED OR PROCESSED FOODS. Well it's Jan 26 and I am up 20 lbs, so I'm trying it again. I was introduced to Mudslides (what a drink!) :-) Anyways it does work but you have to watch what you eat and at least walk around some. My first week on Phen I lost 8 lbs!!! But we all know that's water. Just don't give up! I bet if I just don't drink, it melt right back off."

For Weight Loss: "Had to order as you can't get these in the UK. I originally purchased from a supplier online which ended up being fake. I was so so stupid but desperate. I then had a friend recommend a USA based company, and have started taking today. I'm a 50 year old woman weighing 14 stone 6 lb, and hate my self, I used to model years ago but due to Medication have piled the weight on. I'm off to Mexico in June and just need to get the weight off. I'm going to pop a review on every week. And I'm going back to the gym, just praying this is finally going to make the difference, I've never been a big eater food doesn't interest me really but I do love my wine!!!"

For Weight Loss: "I started taking this back around the last week in December of 2015. It is now January 24, 2016. I have only lost 6 pounds. I am very active and my diet has improved drastically, so I don't know why it hasn't worked for me. I have been debilitated by the crippling headaches up until 2 weeks ago. The were like the worst headaches of my life on a daily basis for weeks on end. I thought I was going to loose my mind and my job. Yes, I stayed hydrated and ate right, so it wasn't that. I'm dissapointed. I'm going to stop taking it now because research says tolerance sets in after a few weeks and one should discontinue therapy."

I have 60 more lbs to lose and I am so excited that I will achieve this goal!! This medication is nothing short of a miracle!! It works !!"

For Obesity: "I started on phentermine 37.5 mg on 12/11/15. 5'11" 364 lbs. At my first 30 day weigh-in after watching diet, eating 3 meals and 3 snacks a day, drinking lots of fluids (mainly water) and staying between 1200-1500 calories, I weighed 351. I lost 13 pounds. Wow! My next official weigh in is in 90 days and my doctor thinks I will be down at least another 30 pounds. I am also using the Fit Bit tracker. I am slowly increasing my steps per day and adding everything that I eat or drink into the calorie counter. This makes me more accountable."

For Weight Loss: "Last year I started taking phentermine 37.5 mg and lost about 15 pounds, but when I stopped I gained it all back. So I went back on it December 1 and started Weight Watchers at the same time. Eight weeks later I have lost 21 pounds. And my cholesterol has dropped 30 points already from 189 to 159. The key this time around is the WW. You're wasting your money on the Phen if you don't follow some sort of diet program and learn to change your eating habits for life. My downfall last year was thinking I could eat anything I wanted and not gain weight, and that's why you gain when you stop taking the pills. I am 59 years old and can't do that anymore."

For Weight Loss: "I just started this medication on January 19th. Here it is, January 22nd, and I'm already down five pounds! I'm only on 15mg, but five pounds in three days is fantastic. It has completely suppressed my appetite. I used to only want to drink cokes and snack all day, but now I'm more into water than soda. So far, the only side effect that I have experienced is dry mouth."

For Weight Loss: "My doctor recommended this to me 6 years ago for weight loss, which now seems an irresponsible thing for a doctor to do. I lost weight quickly at a rate of about 3 pounds a week.By the 3rd week I was experiencing side effects like constipation and some dizziness. I decided the side effects weren't worth it and stopped taking them I have been able to lose weight through natural means"

For Weight Loss: "I've used this drug 2x's. First time I lost about 20 pounds, which was awesome but after prescription ended, I gained most of the weight back even after I swore I'd never do that. 2nd time I used, no real results, guess my body adjusted to the drug. Each time I took for approx 4 months. My suggestion, achieve weight loss the old fashioned way, workout and make smarter food choices. Track what you eat too. I know that choice isn't anyones favorite, but its natural and much better than artificial drugs. This drug causes insomnia, and crazy mood swings, and irrational thoughts and behaviors. Do yourself a favor, don't use this. While the promise of quick weight loss is so tempting, the long term effects outweigh the positives."

phentermine not worth it (taken for 6 months to 1 year) January 19, 2016

For Weight Loss: "I took Phentermine and ended up with open heart surgery...I had success with the drug but eventually developed fluid around my heart which turned into a gel causing my heart liner to be glued to my heart and I couldn't breath and it took 2 months for the doctors to find it because my EKG and oxygen levels were fine, I went to the emergency room and an MRI found it right away, they had to do open heart surgery and peel my heart liner off my heart. I was exercising and was the healthiest I had been in years, running 6 miles a day and riding my bike 20 miles and all of a sudden I just couldn't breath and was so tired. Now 4 years later I can not run or do any aerobic type of exercise because I get to out of breath. STOP taking this drug!!!"

For Weight Loss: "I started the medication on December 17th 2015 at 6' 1 332lbs. As of today I am at 317.4. I am extremely happy with this weightless and medication. Goal weight is 250. I'm extremely active and I am police officer, female. On December 27th, 2015 I fractured my ankle at work and haven't been able to work out since. I was going every day for 2 hours and running a mile each morning. Portion control is key. I was still able to lose the weight by drinking vegan type protein shakes for breakfast and vegetables and chicken breast. I go to the Dr. today for my refill and weight check. Ill be sure to post the inches lost. Main thing is to keep pushing and keep working out. The pounds will be shedded. Remember to eat to avoid those nasty headache"

For Weight Loss: "Hi! So I started my journey on 12/17/15. I made an appointment with a weight loss doctor and started phentermine at 37.5 mg on 12/18/15 at my highest weight EVER, 334.8lbs. So I had my follow up appointment on 1/13/16 and I weighed in at 320.6!!! That's just by cutting out fast food. In a little over 3 weeks, I lost 14.2lbs! I'm going to start working out to see how much I will lose before the next appointment. Yes the side effects are crazy. Dry mouth, and lack of sleep is what I experience but I know my body will adjust with time. You have to choose between staying overweight, or take control of your weight. Just stay strong! It will be worth it when you are truly happy and healthy!! I will keep you posted after my next appointment."

For Obesity: "I have been struggling with my weight for a few years now. I was more and more depressed and my anxiety was through the roof with all the weight I was gaining. My doctor offered me phentermine and because of all of the things I have heard about it I said no. About 6 months went by and I was continuing to gain weight. I finally gave in and decided to give it a try. Thank goodness I decided to try it for myself and not listen to what I had heard. I was very afraid to try it because I do have major anxiety. I tired it on a Sunday when I didn't have to be at work. It was such a great decision. I have not experienced any of the side effects except my breath isn't the greatest. I have been taking it for almost 2 months. It has helped me lose weight"

For Weight Loss: "My Dr prescribed me phentermine 30mg & I'm also getting B12 injections weekly. I took the pill on 01/13 weighing 184. It has helped me suppress my appetite and curb my cravings. I also work out and try to stay under a 1500 calorie diet my Dr advised me to cut out sugars and carbs. I weighed myself today 01/14 (I didn't want to but was just curious) and I weigh 180. I know this is only day 2. But so far it's working!! My goal is to weigh 160! Good luck everyone on your weight loss journey"

For Weight Loss: "I just started taking phentermine as of 01/12/16 my weight is 191 and I am 29 yrs old. My goal is to loose 65 pds! Well for this 3 days so far I have a lot of energy and my cravings for food have dropped. I work in a sit down job all day and sometimes were slow and so I eat all day to keep me from boredom. I been working out for 30 mins because I actually have the energy to do it and watch what I eat. It is great to eat small amount and feel satisfied I have not been able to do this since I was a teenager. I definitely have dry mouth all day so I carry water with me everywhere and a little jittery at times but I feel it is worth it. I will post back in a month to report my success."

For Weight Loss: "I have been taking Phentermine for 20 days now and I have never felt better! I am 21 years old I started out at 289 Lbs and is of today I'm 274 lb with that being said I have done a total life change. I quit eating fast food, and any sweets, no soda or energy drinks, and the hardest one for me is I have dropped from drinking around 30 beers a week to my limit or 2 a week. It has been hard but I know it is totally worth it! The only side effect I have seen is my blood pressure seems to by high for the first couple hours I take it."

For Weight Loss: "I am 39 and weigh 191 . I had a surprise 'its not really menopause - its a baby' 7 months ago. I lost 20 out of the 25 lbs I gained being pregnant. Then in November I had a partial hysterectomy. And gained back what I had lost in 2 months. That sucked. So today I went to my primary care Dr and asked for adipex...most drs won't prescribe it but she agreed I needed to lose weight. I've taken phentermine before in my 20s with great results. Wish me luck on losing! I'll update again in a week."
