Reviews for Phentermine

Adipex-P (phentermine) for Weight Loss: "It does work. You have to work with Adipex though. You have to stay hydrated. You have to eat at least 1000 calories if not 1200 daily. You have to exercise a little. Even if it is just walking. You need to also take it very early and take it around the same time each day. Like 6am. 7am. I would not go past 8am if you are sensitive to medications. Otherwise you will be up all night long ready to run around. You also need to change the foods you eat. We are fat because of what we eat. This is not a magic pill that will melt your fat away. You need to correct yourself for it to really help you on your weight loss journey. This is all common sense. It raises your heart rate up (it's almost like speed). That is what gives you the energy that we are all lacking. For me Adipex is a fantastic appetite suppressant. Good Luck."

For Weight Loss: "Over a 2 year period I gained 75 pounds. I felt terrible. I started exercising 4 times a week for an hour and put my self on a strict diet, only to lose 2 pounds in 2 months, I was completely discouraged. 1 month ago my doctor prescribed me phentermine and told me to start with 1/2 a pill a day until I felt comfortable taking the entire pill if I needed too. I have lost 16 pounds! At first I got a little tired during the day like my insides were on over drive & my body couldn’t keep up with all the energy. I also didn’t sleep well the first 3 days but I feel great now and I’m seeing results! I started to exercise every weekday for at least 1 hour, I stopped the strict diet and just have everything in moderation. I make sure I eat multiple small snacks during the day, If I don’t I start to feel sick. I still go out to eat with my friends and family I just bring home a few days worth of left overs to pick at. It’s definitely teaching me portion control."

For Weight Loss: "Started the phentermine medication and you do immediately experience less interest in food! Miracle. I needed to have become more informed because although I walk frequently I want drinking enough water. Became very dark feeling. Stopped it after two weeks had lost about four pounds 5’4” 170 yet also still held on to my habit of wanting to snack while reading and relaxing. Restarted today and will hydrate way more. Tomorrow will take half of the normal dosing. Yes heart rate went up by about ten beats per minute. Have low blood pressure so that didn’t matter (well other than additional strain on heart?) As I continue taking phentermine may even have a bowel motion only every other day. Absolutely been consuming more fruits and veggies and meat versus fried and white. Because truly after I’m done with the prescription, I want these habits to stick."

Fastin (phentermine) for Weight Loss: "Do NOT use this product. It’s has a strong caffeine-like effect I took it and had the worst possible headache and felt so nauseated. Yeah no wonder you’ll lose weight, you’ll feel so sick you won’t want to put anything in your mouth. Gosh I feel so lightheaded after taking this. Definitely do not recommend."

Fastin (phentermine) for Weight Loss: "I was weighing 189 lbs, started taking Fastin 5 days ago. As of today my weight is 185 lbs. The only problem is the restless after taking the pill. My heart beats so fast.... at first I thought I was dying. The heartbeat goes back to normal after 3 hours of taking the pill. I take 1 pill after breakfast and another 1 pill after lunch that’s all. This pill really works"

Adipex-P (phentermine) for Weight Loss: "Started Apidex on April 1, 2019 and lost 10 pounds, I went back to the Dr. April 29th and found out I was pregnant after not being able to conceive in 15 years. Dr. told me that Adipex makes you very fertile so I guess that was a boost to me getting pregnant, but now I’m about gain those 10 pounds right back in the best possible way lol"

Adipex-P (phentermine) for Weight Loss: "My backstory: On January 1st I started dieting with the low carb diet (a mix between Atkins and keto kinda) then I weighed 213.8lb. And at the end of March I weighed 199.6lb so I lost 14lbs In March I was tired of keto and stared just eating smaller portions of non diet food. At the end of March I weighed in at 195.2 so not terrible but also not the results I previously had. On April 15 I started the slimfast diet. And on April 24 I went to the doctor to get Adipex and weighed in at 191.2lb today April 26 I have just taken my fist Adipex. I’m excited to see how this goes. I’m going to continue to do the slimfast for the first month, I’d like to see 176lb when I get on the scale at my follow up appt. I’m a nurse and I work shift work and on my off days I tend to cheat badly. I plan to workout 3 times a week. My end goal weight as of right now would be 150. I’m 5’5 and I feel like I carry my weight pretty evenly."

For Weight Loss: "I am 21 and on dose of 37.5mg of phentermine, I was put on this because I have Hashimoto’s hypothyroidism and gained about 70lbs so my doctor prescribed this to help me to help with weight. My starting weight was 184 and I am now down to 170. My first day on the pill was March 28th, I have taken my pills for about 3 and a half weeks and am down 14lbs already, my goal weight is 140-145. I haven’t experienced too many side effects other than increased libibdo (like way too much). I also never can eat, it makes me extremely sick when I do because I have to force myself and I’m just never hungry, I also don’t have bowel movements like I used to. I’ve been eating healthy, no gluten at all & no more than 10 grams of carbs a day, I lift weights & do HIIT work outs 4 times a week at the gym"

For Weight Loss: "I’m a 54 yr old female at 5.6 and 183 lbs. I have been experiencing weight gain do to IBS and water retention. I am taking Gabapentin and have had cortisone injections due to spinal stenosis. I am only one day (April 17,) in for taking this medication. I took the whole pill as prescribed an hour after breakfast. 37.5mg. Within the first hour, I experienced heart palpitations which lasted within 30 min. I also experienced insomnia. I am looking forward to taking this medication and will follow up within a month. Good luck everyone!"

For Weight Loss: "This is my first day taking phentermine 37.5 mg. I took it 2 hours after breakfast. My typical morning I feel groggy & yawning frequent. I also have RA & take Effexor 150 mg which leaves me fatigue. So hope this will change in energy surge as well as weight loss. I’ve lost 30lb since May 2018 but been plateaued since October 2018. Got my diabetic check & getting off insulin & Januvia but keeping Byetta; hope this is in an aid to continuing weight loss. So far I haven’t felt different, still yawning but this afternoon I feel slightly reved up. My vitals showed my heart beating 103 usually in the 90s. My temperature 98.3 usually 97 5 so could be from the phentermine or walking to o my appointment. Stay tuned. Prayers for success & no issues or complications."

For Weight Loss: "I lost 48 pounds on phentnermine from September 2016 to January 2017. I noticed that the yellow phentermine worked better than the blue ones. Anyone have any experience with that? I definitely had no appetite and I was on no carb diet. I drank a lot of water."

Fastin (phentermine) for Weight Loss: "Consumers I've been on Fastin off and on for about a year now. I read most of the comments before posting my experience. I usually only take 1 in the morning before I worked out to give me the energy I need to complete my 5 mile walk. If I'm not working out that day I take half of a pill due to the fast heat rate and slightly the jitters. Too be honest I haven't seen much of a weight lost. Could be I'll start for a week or 2 and then stop. My issue is I need to be consistent with working out and taking the pill to see results. I do believe they would work if taken properly. I read one comment and the consumer said she lost 35lbs so that there is inspiring me to push forward to achieve my weight lost goal."

For Weight Loss: "I’ve used phentermine on and off two times since August of 2017. I’m a 25 year old female. I’m 5’3”- maybe 5’4” on a good day. My highest weight was 184 lbs and I was MORTIFIED. I’m an emotional eater and was obviously using food to cope with life. I took 1/2 a pill a day (I have ADHD and am afraid what one whole pill a day may do). The first time I took these pills, I did not exercise or eat healthier at all- and by October 2017 (two months of half a pill a day) I went from 184- 154lbs! 30 lbs in two months!! It is now April of 2019 and I have gained back some of the weight I’ve lost, but not all of it. I currently weigh 164 lbs- only a 10 lb gain in a year and 8 months. I started taking this pill again- today is Day one! And I’ve decided to incorporate exercise and a healthier diet as well. My goal is to reach 145 or less. I will update at the end of the month!"

For Obesity: "I lost 3 stone on phentermine - but the side affects are a bit annoying, I get anxiety, I can't sleep and I have mood swings - oh and bad taste in mouth. Worth it though, if you're overweight"

Adipex-P (phentermine) for Weight Loss: "I'm 5'3 female 39 yrs old my starting weight was 213 lbs . The 1st week I lost 15 lbs my biggest loss. Today I had my 1st month check up to get a refill and at my weigh in at the Doctors visit I was 190.8 lb. I started walking at 2 1/2 week mark I could only walk for 30 mins at first then I begin to walk for an hour. I had no energy when I first started taking the pills. I bought some vit b12 and when I took this it gave me the energy that helped me to start walking. I only take one b12 a day. I also take a multi vitamin and fish oil pill. I eat similar to the HCG protocol its not a miracle pill you have to have self control over the things you eat and choose food wisely."

Adipex-P (phentermine) for Weight Loss: "My first day was great, I ate breakfast and had no appetite for rest of day. Next few days same thing. However following 2 weeks began to feel hungrier after eating. Think I may have lost 1 pound with exerise in 3 weeks. Would not advise, the effect wears out."

For Obesity: "I'm on my 5th month of Phentermine for weight loss. I was originally prescribed it for 3 months, but since I'm doing well with NO side effects, my doc gave me the option of taking it for up to 6 months. After 4 months, I'm down 37lbs. Right off the bat I started walking EVERY DAY (and still do 5-7 days/week). I also limited carbs since I had NO cravings. The weight came off steadily for a bit, but I'd have weeks with no weight loss because I wasn't eating enough. I was stalled at 27lbs up until 3 weeks ago, so I joined WW to make myself eat. At that point, I also started taking Phentermine every other day, instead of every day to get my body used to it's natural state. I have lost 10 more lbs since starting WW. While Phentermine really is a "magic pill", you do have to put in the work if you want great results. It is best to use it as a tool to form real habits in the time you're on it so you hopefully won't gain when you stop! That's my plan at least!"

For Weight Loss: "Prior to using 5'4" 165 lbs with hypothyroidism on medication. Working out 3 days a week (500 am). Ate small portions but love carbs. Just completed 3rd week of 37.5 phentermine and adding Keto diet (30 carbs/ day). Continued my earlier exercise. I am now 154 (down 11 lbs). Feeling like I'm pushing my self to eat. Thinking about decreasing dose in half. My goal has not been reached (140 lbs). I will up date in 3 weeks whether decreased dose or not and if I continued to lose weight."
