Fastin (phentermine) for Weight Loss: I took this and it's the best thing I have ever tried. The first couple of days I went by the directions then I doubled the dose. And I lost 20 pounds in 2 weeks. It did make me feel very jittery and my heart rate was going 90 to nothing but I was determined to lose weight.! And a little information DO NOT I repeat ( DO NOT ) take Fastin before you get in a tanning bed. Tan first then take it. It made me very very strange in a bad way. I'm no doctor but when I increased my dose I had the shaking and the increased heart rate. But It never harmed me.

Adipex-P (phentermine) for Weight Loss: 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: I started phentermine on 10/11/14, start weight was 249. As of today 10/14/14 I am at 241. That's 8 pounds that I lost in 4 days! I did change my eating habits to low fat and have walked 3 miles every day. Also, I have been drinking only water. I cut out my diet coke that I was addicted to.(if I can do it, anyone can do it!). I feel great with no side effects. I truly believe in this medicine. The only thing you have to remember is that it is a lifestyle change. I wish everyone the best.

Fastin (phentermine) for Weight Loss: I am borderline average/overweight for a 5'3 woman just wanted to lose about ten pounds. Extremely effective but as the other reviews state two for me was way too much! Uncontrollable shaking but the heart pounding was nothing less than frightening.

Review by losing it! (taken for 1 to 6 months):

For Weight Loss: When I started Phentermine I weighed 181lbs. Today was my 1 month weigh in and I am at 167lbs. I have lost 14lbs in 1 month. I am 5'6 and 22 years old. I am coupling Phentermine with a healthy low carb diet, around 1,200 calories a day with only 20 minutes of cardio a day. Loving the results and have had no serious side effects other than trouble sleeping for the first 2 days.

For Weight Loss: I am 5'1 and weighed 132 lbs when I started taking Fastin after 3 months I had lost down to 107lbs. I never did exercises and I ate any and everything I wanted and the weight just kept dropping. So to me this is the miracle. I would definitely recommend this to anyone.

For Weight Loss: Started taking phentermine 9-26-14, I weighed 196lbs. Had my first weigh in today 10-9-14, I now weigh 187lbs. I lost 9 lbs in 2 weeks. Side effects I'm having are dry mouth, headaches and stomach pains, but that could be my loss of appetite throughout the day and not eating. And insomnia. I was taking the pill at 10am. I am now switching to half a pill and at 8am. Will see if it works better for me.

Adipex-P (phentermine) for Weight Loss: I took phentermine for six weeks and lost 22 pounds. I'm 25 years old. My starting weight was 182lbs now I'm 165lbs. This pill is the best I've been off for three months and have only gained back five pounds. I will restart again in November.

For Obesity: So far this is absolutely the best aid in losing weight for me. I had lost 75 lbs in 2011 with Weight Watchers but gained about 38 lbs back between 2012 and 2014. I went to the doctor and he put me on phentermine & chromium picolinate. I have been on this since 8/23/14. In 6 wks I have lost 25 lbs. It has significantly decreased my appetite to where I don't even think about eating and have to remind myself to do so. The only side effects I have had are dry mouth, which causes me to drink water constantly (so not a bad thing), mild insomnia the first 2 wks & constipation, for which I just take a supplement. BUT you have to eat right. Reduced carbs for sure. Weight Watchers taught me healthy eating so you do have to change your food.

For Weight Loss: I started taking phentermine due to some weight gain after a spinal fusion I had in April 2014. I can't do much exercising because I am in pain all the time. I started taking phentermine October 1st 2014. Today is my 4th day I have lost 11lbs. I weighed in at 212lbs and today I weighed in at 202lbs. It's hard to change eating habits but I am doing this so I don't have to have another surgery. Not everybody has the same body make but if you are determined whether you shed the lbs fast or slow this diet pill works. I recommend it to anyone who's willing to take charge of their life. Only you can make that change. Only side effect is dry mouth which means you will want to drink a lot of water.

Adipex-P (phentermine) for Weight Loss: I know everyone is looking for a miracle weightloss pill well let me tell you Adipex is not it. Adipex in my opinion is a special."Helper" yes it definetly suppresses your appetite and gives you a boost of energy. But ultimately you have to change your lifestyle to compliment this. I cut out sugary foods, fast foods, fried foods, and carbs. I drink plenty of water, and workout 3 times a a week with cardio. I do 4 and half miles on the treadmill on a 8.0 incline. Tomorrow makes a whole month and I have lost 25lbs total... And I'm going into my second month fighting harder.

For Weight Loss: Works great for weight loss but I stall after three months as my body gets used to it. Doc gives me lorcaserin during off month to kill my appetite then alternate back to phentermine seems to make it work again. Lost 60lbs but unfortunately will need surgery to get excess skin off mainly in belly area.

Adipex-P (phentermine) for Obesity: I started Adipex on 8/30/14 and as of 9/15/14 I've gone from 202 to 185lbs. 17lbs in a little over 2 weeks, I'm 5'6" and borderline diabetic. My doctor has been on me for the past 5 years to lose weight. She says I'm considered obese and will have to put me on medication for the diabetes soon, but my wake up call was when my joints started aching, and I was losing feeling in my feet. In addition to Adipex, I've eaten 85% clean, opting to snack on baby carrots instead of cheese and crackers. All I drink is water, I've cut out the alcohol, coffee and all fats and sweets. I walk everywhere and have lots of energy. I take 1 pill between 9:30 & 11am every day, and I fall asleep by 10:30pm. My goal is to be around 150lbs.

Fastin (phentermine) for Weight Loss: It really works, you must eat before Fastin, then go to the gym, if you feel your heart hoes quick. Just take half pill and everything will be right. I'm 35 year old and with gym and my half pill of Fastin I feel perfect in my weight of my 15 year's past.

Suprenza (phentermine) for Weight Loss: I started in July. I was eating healthy but wasn't working out. The one week I started working out I lost 8pounds and no I don't take them every day. But working out is a plus. My goal is 175lbs, I am 240lbs, after a baby.

For Obesity: I am a 51 year old Grandma of 6. I started Phentermine 7 weeks ago. I have lost 18 lbs. It started working the first day! I stopped drinking pop, eating garbage foods, etc. I just don't care about that stuff anymore. I believe this is a gift, and want to get everything out of my 3 months that I can. I get on the treadmill every morning for at least an hour, lift light weights for 5 minutes while I walk, drink a lot of water. I look so much difference and feel really great! I am nervous when the pills run out. I really love how this is going and am afraid of what will happen when I am on my own again. My side effects are dry mouth, and constipation, two things that seem really small for the benefits I am getting. I feel fantastic!

For Weight Loss: Update: Been on phentermine for one month-lost 11 pounds. Reduced sugar intake drastically, drinking only water. Continuing exercising 3-4 times a week. Wish I could lose faster but slow but steady is working.

Adipex-P (phentermine) for Weight Loss: I started Adipex a year ago. Lost 50lbs in 3mos. Then got pregnant. Had him 2 months ago. And only gained 15lbs during and lost right away. But I still didn't reach my goal. So I'm on it again. I'm on day 4 and down 5lbs. I love this pill! Never exercised or dieted before but I'm going try this time.

For Weight Loss: I have been taking this medication for a week. The first day I did felt exhausted and slept my day away. So far I have managed to lose 4 pounds in seven days. The only side effect I have is dry mouth. I bought myself a refillable water bottle to carry with my at all times.

For Weight Loss: I started Jan 3 2014, the first week I lost 10 pounds! It's now 8.27.14 and I've lost 55 pounds total. I have been slacking and not working out but I love it. Dry mouth I still have it but makes you just want to drink water I have recommend tons of people! But I also take it at 5:00am or 4:40am and workout for half hour and then again at night for an hour or half hour gives me a lot of energy makes you sweat an not as hungry either. I would recommend it trust me they work.

Adipex-P (phentermine) for Weight Loss: I started Adipex on 8-18-14 & today is 8-25-14. I am down 8 pounds in a week. I hope this kind of weight loss continues but I'll have to wait & see. I did experience a little bit of nausea for the first few days but it wasn't too bad & dry mouth a little. So far I am pretty pleased.

For Obesity: Started phentermine 37.5mg in April 2014. I have lost a total of 25.6lbs to date. The key to doing this right is watching/tracking what you eat/drink and finding a workout routine that works for you. I elected to join weight watchers because I walk to be help accountable by someone other than myself. During the last 4 1/2 months I've never had a week that I've gained. I have stayed the same 5 separate weeks but no loss is better than a gain to me. I travel a lot for work, so food wise, it's all about choices. Just because you're not hungry remember to eat at a regular scheduled time if possible. Don't go all day without eating. Losing weight to fast may make us happy but it's not healthy. Good Luck everyone.

For Weight Loss: I started taking phentermine August 15, 2014, weighed 203lbs, today 197 lbs. I've only drank water, had ONLY 3 sips of tea, calorie count varies between 600-2000. I have not cut out sweets/fried foods. I'm not cutting out all those that I enjoy eating, I'm cutting back. If I cut out everything, once I finish phentermine, the weight will come back rapidly when I start back eating regularly, this has been my experience when taking phentermine previously. I'm not going to eat just fruit, veggies, broil foods for the rest of my life, so why fool myself? I'm working out 6 days a week, in the morning and evening. This round will be much better, I'm more determined, my strategy has been thought out. I will post an update, BEST OF LUCK TO ALL!
