For Weight Loss: "I'm a 52 year old women, moderately active through golfing and walking, and a relatively healthy eater who never has dieted and didn't need to. Menopause, age, activity level and metabolism has each contributed to a 35-40 lbs weight gain. After a year of increased activity and reduction of calories and carbs such as pasta, potatoes and breads, I was not able to really maintain a 5-10lbs weight loss if I didn't walk at least 5 miles each day. I noticed there was an overall reduction in energy. My doctor had been on this journey with me; food journals to now Phen. 37.5 mg. In 12 days I've lost 8.6 lbs. I do have a dry mouth and a suppressed appetite which I hope over the 3 month prescription will help me to reduce portions considerably."

Adipex-P (phentermine) for Weight Loss: "I just started this medication on June 12 starting weight is 184 I am down to 179 already. My primary doctor advised that I do the name brand of the medication for the first month and than the following two months I have the choice of generic or name brand. Like most I have tried all the fad diets and pills and spent countless money on stuff that just did not work. Now Medical I have RLS (restless leg syndrome) and I have not had a problem with this medication effect the medication I take for that. Only real side effect I have seen so far is dry mouth even though I am drinking anywhere from 64oz water or more a day. I have increase energy which is great. I will update more results as they come. Also my insurance does cover some of the cost."

For Weight Loss: "I'm 5'7 and at a current weight of 209. I've been yo-yo dieting for several years, losing 20 - 30 lbs, gaining it back and then some the next year. My GW is 149 (60 lbs total). I started 37.5 mil of phentermine 3 days ago and am already down 4 lbs! The only side effects I've had, so far, are extreme thirst (which is good) and TONS of energy (which is great). Hasn't kept me up at night at all (other then the constant trips to the bathroom!) I am also exercising about an hour a day, either walking or some sort of cardio, and eating small, healthy, frequent meals throughout the day, which I have to remind myself to do since I have NO appetite. :)"

For Obesity: "Update so I started taking this on May 19th, 5ft tall and 250 pounds. I felt dizzy my first three days and ate very little. I try to eat less than 1200 calories a day. Some days I'm still hungry though. It hasn't even been a month and today I weigh 224. That's 26 pounds in 27 days almost a pound a day with no exercise. The results for me have been amazing. I do have trouble sleeping so I usually take the pill earlier in the morning. I take a whole one a day. I also have had severe dry mouth mainly the last 3 days but I'm also taking a water pill."

For Weight Loss: "I love the results of taking this prescription. My only issue was my mood swings while on them. I seemed to be mad a lot. So I started just taking half a pill and it only got a little better. That is the only reason I gave it a 9 and not a 10. It works, but the effects it has on my mood are not good."

For Weight Loss: "Hi. I have been on adipex 30 mg for almost a full week. I am 49 with high blood pressure, in menopause and recently diagnosed diabetic. My Dr put me on it because no matter what I do I can't seem to lose weight but keep gaining. When I eat healthy and exercise I do lose inches but no pounds. I am 5'7 and 202lbs. I have never been this big. I think I can see a difference but I am so afraid to get on the scale. My Dr has told me in the past I'm fighting an uphill battle. I have been skeptical and when I read of so many seeing such great results, I do not want to be devastated if I don't see any. My plan is to join a gym in the next couple of weeks as I am not good at exercising on my own."

For Obesity: "Started on Tuesday June 6, 2017. Staring weight was 278lb (126 kg). Today is June 8, 2017. My weight is 269 (122 kg) I also got a B12 shot but it made me sleepy. Has anyone every experienced this? Next Saturday I'm going to try the Lipoden shot. I also went for a two mile walk yesterday and I plan on walking everyday and going to Zumba as well. I started a new job and there's an on site gym. So on lunch I might jump on the treadmill or walk around the building. I'll keep posting updates on my progress.."

Adipex-P (phentermine) for Weight Loss: "At 280 pounds, recently diagnosed with Type 2 Diabetes, and told to start medications, I turned to my doctor to discuss potential stomach procedures. Well, with 1 Kidney, I'm pretty certain Diabetes would eventually cut my life short so why not go through a drastic change? No.... instead I asked her for three months to lose 30 pounds, and she suggested I try Adipex/Phenermine 37.5mg So like many all of you, I did, and I instantly felt that sudden feel good surge of energy. I'm now 10 weeks in and lost 33.5 pounds. Some will read this and many of your posts and instantly think it's a fake review. But honestly readers, this pill has changed my outlook on life. Give it a shot, it may not work for all, but it may work for you!"

Fastin (phentermine) for Weight Loss: "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!"

For Obesity: "I started this pill April 13th 2017. I am 5'3 and starting weight was 199. I am also turning 27. So far my weight as of today is 186. At first I was really seeing some weight shed when I stepped on the scale and it kept me motivated. Now, not so much. I keep teeter tottering my weight each week. I gain a point, loose 1.2 lbs. gain another lb, lose 1.4 lbs and so on. This has been happening for the last 3 weeks. I'm discouraged seeing so many people losing 10+ a month where I'm almost on two and only down 13 lbs. is this normal? Idk what I'm doing wrong. Is a temporary and will kick in again where I lose more rapidly? Idk what to do. I am going to quit by all means, but I do need some encouragement. I see the doctor tomorrow. Will see"

Adipex-P (phentermine) for Obesity: "I work at endocrinology clinic. And there I have seen crazy stories about Adipex-from 191 lb in 1 year to 30lb a month. So, I said to myself I'm going for it. In first 3 days I am 4lb down. I have plenty of energy, I do have a dry mouth and one time after I stood up from the bed I felt dizzy. Now my post is more for the people who are taking it- plz take 1200 cal per day. If you take less, you will have jitters and you would start doubting the med. And yes, I push myself to eat, because I want to eat, but I eat small portion. From day one I want to adjust my portions, always small portions. After 1 months after my med finish, I will continue small portions and wont pass the 1200 cal. Good luck.."

For Weight Loss: "I started 5/26/2017 on one 37.5 mg tablet daily, my starting weight was 220 lbs, and one week later I am down 10 lbs, I weighed myself this morning and I weighed 210! I had to completely cut out all simple carbs like bread, pasta, tortilla, and also absolutely no sweets which is my downfall but to be honest I have no interest in any of those foods because the results I am seeing are more addicting than the food! I stay under 1200 calories a day and I drink 1 gallon of water a day. The only side affect I have noticed is dry mouth, and when I workout really hard my heart rate did creep up to about 198 which freaked me out a little so I had to tone it down a bit on the run that day. I have also workout 5 days a wk. It's been worth it so far!"

For Obesity: "Hello everyone. I'm a 30 yr old female. My starting weight is 396. I went to the Dr looking for help. He gave me a choice between 2 meds ( phentermine and contrave). I choose phentermine. I started taking the pill on May 4, 2017. He suggested I start taking half a pill just in case it would speed up my heart rate. After 3 weeks of taking half of pill I started taking the whole pill. I've been on the pill for a month and I have the most energy. The scale says I'm down 19lbs!!! My clothes pretty much fit the same but I can feel I difference in my walk. My back ache is no more. I can stand and have conversations at work without looking for a chair or leaning against something. I have changed the way I eat also. I cut out fast food."

For Weight Loss: "I started taking Phentermine 37.5 mg in April after I went to my doctor appointment and weighed 172 lbs. This was up 14 lbs in 1 year. I am 5 ft 7 in, 52 year old woman going through menopause. I absolutely flipped about how my weight keeps going up and my doctor suggested I try this a couple months. It has been a great success, on June 3 and I'm down to 159. Had a lot of side effects though. Besides the dry mouth, I have terrible insomnia, so bad I can only take like three days in a row then I need a break so I can sleep. Worse, I have been really cranky with my boyfriend and crying way more than normal. I still have 25 pills left, but I don't know if I'll take them. Will update later."

For Obesity: "37 yo, mother of four children; 18y, 12y, 2y, 10 mos. I've been overweight then obese pretty much all my life. The older I get, the harder it is to try to lose weight it seems. My Dr. put me on Phentermine 37.5 last week. As of that appointment on 5/25 my starting weight was 260lb. As of 6/2, my current weight is 252lb. it's a huge challenge to try to eat as my appetite is GONE this first week. It's slowly coming back. the energy boost is great and much needed with 4 kids!"

For Weight Loss: "After gaining 90lbs through the last 4 years of nursing school, my heaviest weight of 277lbs when I asked my MD for a px for Adipex. I started taking phentermine (Adipex) 37.5mg daily every AM on May 9th and weighed in at 267.2lbs May 17th, 266.1 May 25th, and 263.9 June 1st. I also do between 30-60min strength training/cardio 3-4 times/week at the gym. After my first week taking this px, I did find myself needing to pay more attention to eating small meals 5-6/day or the side effect of dizziness would occur. Dry mouth is also a side effect which I've noticed so I bring water with me everywhere to get my fluids in around 3200mL. I started taking half this dose the other day to decrease the dizziness which has been effective."

For Weight Loss: "I started taking phentermine 37.5mg on Feb 28, 2017. I am 5'7, and weighed 264 pounds at the time. I did not loose much due to me being inconsistent with taking the pills. Once I became consistent accurately, in March I lost a total of 11 pounds for the month. (253). In April, I was on a second refill, but someone stolen my pills, so I was not able to take anything for the month April. Refilled on May 13, 2017, weighed in at 258, I gained 5 pounds. On May 24th, two weeks after taking the pill I lost 8 pounds which put me down to 250. The main point of all this is to be consistent, with taking the phentermine, exercise, eat your protein, and drink water water water water. I drink a gallon of water daily. I hope this helps someone!"

For Weight Loss: "I'm 5'3" and last year I was at my heaviest of 267. I started on phentermine last year for 3 months and l lost a total of 38 pounds. I kind of fell off the band wagon of going in each month for a new prescription and how busy my life got and ended up gaining 13 lbs back in a year. But ready to get back on the band wagon and go for at least another 38 pounds if not more."
