For Weight Loss: "I have now been on Phentermine for a week. I have already lost 5 lbs. I need to lose another 20. I am not obese but am on two cholesterol medications. I always weighed the same until my thyroid medication was too low and I gained 20 lbs. I could not get it off no matter what I did...until Phentermine came into my life. I am experiencing none of the side effects except dry mouth. What I am experiencing though is 1) higher energy; 2) better sleep; 3)a feeling of well being; 4) more focused; 5) less appetite; 6)more stamina. I am only on 15mg per day and feel wonderful."

Adipex-P (phentermine) for Weight Loss: "I'm 5ft nothing, weighed 155.4 when I started.I tried dieting, exercising&weight watchers&kept gaining weight. I was proscribed Adipex Nov 18th, 2015 & the lbs started falling off. I took the whole pill & felt anxious & shaky for about 3 hrs &after that, no bad symptoms. I took it for 2 months& lost 26lbs. I stayed off for a month & I didn't gain a single lb back. After a month off, I got back on, instructions from the doc when I first started& by the 1st wk,I lost 5lbs. I have 10 days left & I am at 118.Goal weight is 115. Adipex changed my life & Losing 30+lbs in 3 months...amazing. I would recommend it to anyone! Also, it is not expensive at all, with or without insurance!"

For Weight Loss: "This medication saved my sanity and my life!! I have multiple severe autoimmune diseases so after gaining 45 lbs because of a horrible reaction to a medication, I didn't know what to do with myself. I tried everything I could to lose weight the "natural" way but nothing worked; my body and metabolism had changed. I hated the way I looked and felt. Thank goodness my family and SO were by my side but nothing helped me. I was THRILLED when I found out about phentermine. I did my research and even though there was scary stuff posted about it, I didn't care...I wanted this weight gone. And gone it went! 30 LBS IN 3 MONTHS! Yes, some people can have bad reactions but that's no reason to give it a bad review because it does what it's supposed to!"

For Weight Loss: "I started Phentermine HCL 37.5 in January 2016, 1/day. I am 5'7" and weighed 200lbs. I am almost at the end of my 2nd month (3 days left) and now weigh 173lbs. Weight loss to date is 27lbs. I am very happy with the results thus far. My doc said he would only allow the use of Phentermine for 6 months at the most. I have a check-up every month and have really put my mind to eating healthy foods and no pop or sweets (which were my culprits). I drink water, but most flavored and never had high-blood pressure. Only side-effect was insomnia for about a week in the beginning. Will start incorporating exercise in month 3 because once you go off, the weight will come back if you haven't taken the time to change your diet and exercise habits."

For Weight Loss: "I took two A.M. doses of prescribed 15 mg phentermine over the course of two days. I experienced "amphetamine comedown" symptoms in the evening of both days, including some minor chest pains and pressure, so I decided to discontinue the pills. I then had to endure a 3-day unpleasant amphetamine withdrawal period. From two small doses. I know I am sensitive to drugs, especially "uppers" and "downers" so I suppose that was the reason why this happened to me while attempting phentermine for weight loss. I will never take it again because I did not feel safe while on it. Just be careful if you are sensitive to substances. Ask for the 8 mg dose to start and know that the drug puts a strain on your cardiovascular system."

For Weight Loss: "I have been on Phentermine 37.5 and Topamax 25mg since February 3rd 2016. I noticed immediately that I cannot drink carbonated beverages anymore after yelling at the poor fast food server that there seltzer machine was bad. I now only drink water or occasionally juice and tea. I did not change my eating habits during this first month but I did notice I would get full faster. I then began noticing that I was eating less and often times having to remind myself to eat. I am 5'8" and began my weight at 311lbs as of March 3rd 2016 I am 290 lbs. This month I have added daily walks around the block. As time goes by I will increase my distance and begin eating a little healthier."

Now at 246 and 5 ft 7 high blood pressure high cholestrol and pre diabetic. I need a jump start and I am praying this drug will help. I have the prescription and starting tomorrow morning 3/4/16.

For Weight Loss: "I started taking Phentermine 37.5 mg Jan. 21. I am a 51 yo female, 5' 3". On that day I weighed 193 lbs. Weighed in again today and I was 177. So far so good. I am eating between 900 and 1200 calories a day. Very lean and nothing complex. Yogurt, salads, chicken, Slimfast meal replacers, steal cut oats, lost of fruits and veggies. Since Jan. 21 I have only had pasta and rice 4 times. I drink a lot of water! I walk on the treadmill for 30 minutes a couple of times a week. I hate working out in the winter time. As for side effects: At first I had a hard time sleeping. My mind would race...felt like I was on speed. Now it is just always thirsty and now and again I clinch my jaw way too tight. Very happy with my progress."

For Weight Loss: "I was on Phentermine for almost 2 months, I started out weighing 175 pounds and now I am at 155.50. I started out with bad headaches, numbness of feet, cold feet, tingling legs and no appetite. I am a 38year old female. I was recently seen at the Dr's office. I went in for my monthly checkup, I was feeling sick my head was hurting bad and I was short of breath. I complained of my feet being numb and my legs feeling tingly. I was immediately taken off the medication. My heart was beating irregular, they said this was a reaction to the medicine and I was feeling sick because my heart was beating irregular. I was admitted from the dr's office to the emergency room. I will now be seeing a heart specialist to see if there's any permanent damage"

For Weight Loss: "I am sure you will not publish this but am curious if it was the same experience for anyone else. It was extremely difficult to understand the representative. They spoke very fast and and were hard to understand as they kept rambling on even when I said I can't understand them. Then they started adding on international banking charges up to 10% on top of a $30 express shipping charge( I don't consider 2 weeks express). Then they contacted my bank who couldn't authorize an international transaction without my permission. I have ordered items from other counties many times and never had this difficulty. . There was also a code for discount that I put in when I asked about it she said you had to be a returning customer????"

For Weight Loss: "I just started phentermine 2/24/16. The only thing I have experienced so far is a need to drink a lot of water which I've done before. I already workout 4 days a week cardio and strength training. I'm 5'7 176 my goal is to be 145 but fit. I was diagnosed with hypo thyroid two years ago weighing 205 pm which motivated me to eat better and exercise. Change can happen when we take care of our bodies. I want to add from stories about weight coming back. If you stay active cardio weight training eating clean, drinking your water and change your mindset from just weight loss you will see long lasting results. But if you go back to eating fatty processed food cakes cookies etc. You will gain your weight back.To a life of health. It can be done ."

Adipex-P (phentermine) for Weight Loss: "Hi, I'm 31 female. Just shy of 5'4. I started phentermine on 12/28/15 weighing 184, now I'm in the middle of my 9th week and I weigh 165, so in 2 months I lost 19lbs, my goal is 145. I weigh in at my clinic every Monday evening. I do cardio & weights 4 to 6 days a week. The first 3 weeks I ate strictly protein and veggies with some fat, I've slowly added in complex carbs and fruit. I drink at least 90oz of water a day and have 3 meals and 2-3 snacks, the days I don't work out only eat the 2 snacks. The side effects I've had are dry mouth, dry skin and constipation (despite my water and fiber intake). I recommend the smooth moves tea by traditional medicinals, but test it one a day where you can be near a bathroom so you know how you react."

Adipex-P (phentermine) for Obesity: "I am a 42 year old woman, 5'0" and weigh 232lbs. I am way too short to be this heavy. Severe depression over the years brought me to this weight. Today is my first day on Aipex 37.5. I took 1/2 pill after having my morning smoothie. I am doing Dr. Oz Day off Diet along with this. So far so good I only felt a bit of a head rush but otherwise the energy is perfect. I'm giving myself until January of next year to complete my full weight loss of 107lbs. I will be walking everyday as well. I will check in with updates every Monday. Hope I can help folks here as well."

For Weight Loss: "I have 50 pounds to lose. I am 57 yrs old, weigh 194, am 5'7'' tall. My weight on Dec, 18, 2015 ( two months ago) was 220 lbs. I am going to Jenny Craig to maintain a balanced diet of 1200 cals/ day. I KNOW this med. works with close medical supervision and no BP or heart disease. I have lost weight successfully and for a long period of time using Phentermine. I am a nurse w/o HTN, known cardiac disease or other risk factors. I tried Contrave and although there was moderate wt. loss, the nausea was too severe to continue. My doctor and I have seen great results with Phentermine, which is a very old, generally safe medication. PLEASE get a physical exam before starting the med. and every month check ups to monitor health, GO FOR THE LOSS!!!"

For Weight Loss: "I just started today weighing in at 162.8 and 5'7" and I'm hoping to reach my goal weight of 135lbs. I already notice a change in less than 3 hours, mouth a little dry but not unbearable, very thirsty and lots of energy. Feeling good about this so far and hope to update on my results. I already started working out and I am on Day 3 of clean eating and exercise so that this transition would be easier. I'm a single mother of 3 so I'm trying to be healthier for them and for myself. I can't rate the medicine at this time but will after more time has passed."
