Fastin
This Phentermine diet pill claims to boost metabolism and suppress appetite.
In December of 1998, the pharmaceutical giant, SmithKline Beecham withdrew Fastin from the market because of side effects associated with this weight loss supplement. Today, it is back on the market, as it tries to help those who are obese lose weight. Phenylethylamine, or Phentermine, is the main ingredient in Fastin. This chemical is a powerful stimulant that boosts metabolism, suppresses appetite and raises heart rate.
Fastin should only be used by people who are extremely overweight or obese and have not been able to lose weight with just diet and exercise. Fastin should only be taken under the supervision of your doctor. It should also be taken in conjunction with a reduced-calorie diet and a consistent exercise plan that has been laid out for you by your medical doctor or registered dietitian.
Fastin contains stimulants that may cause side effects like increased heart rate, shakiness or heart palpitations.
- Fastin may help to kick off a weight loss program
- May help to reduce weight when used in combination with a low calorie diet and exercise plan
- Fastin was pulled off the market in 1998
- Not a long-term solution to weight loss
- Can induce many dangerous side effects
- Should not be taken by certain individuals who have current health conditions
- Should not be used for longer than a few weeks
- Can result in dependence
- Automatically enrolled in the auto-shipment program after registering for free trial
Fastin contains Phenylethylamine HCL, R-Beta-Methylphenylethylamine. methylphenylethylamine tartrate , methylsynephrine HCL , N-Methyl-phenylethylamine HCL, Synephrine HCL, Theobromine Anhydrous, Yohimbine HCL and caffeine.
Given the powerful effects of Fastin, it should only be taken according to the directions of your medical doctor.
Fastin is typically taken once a day 1 hour before breakfast or as directed by your doctor. Since it contains stimulants, you should not take it before going to sleep. Also, Fastin should only be used for a few weeks since it has the ability to result in dependence.
While taking Fastin, you will also be following a reduced-calorie diet comprised of 1,200 – 1,500 calories a day and a consistent exercise program that is laid out by your health practitioner. You should avoid alcohol, caffeine and any other stimulants.
Fastin is a stimulant that works in a similar way as amphetamine. In addition to being an appetite suppressant it is also a mood-elevator. Fastin should only be used by people who are obese and under the supervision of their medical doctor.
It is not recommended for use by individuals at risk for diabetes, high cholesterol levels, high blood pressure, a malfunctioning thyroid, hardening of the arteries, or heart disease or if certain medications are being taken.

I used years ago and had good success. you can loose weight and feel good at same time, but everyone needs to know this as any medication takes a good 3-7 days to get into system and start to work, don't expect to take it and lbs fall off. work with it, if you feel that bad STOP taking it. I am gonna do it again

I have used Fastin before a few years ago with a diet and excersise plan, and it worked very well. My doctor checked to make sure it was safe for me, and I followed her suggested meals and exersise regimens and got good and safe results. Its probably different for different people and not good for some people.

I just started this drug yesterday. So far I have had major headaches, my blood pressure has gone up, I am nauseous and am sweating out of every pore in my body! I thought I would use something to jumpstart my weight loss as I have 4 children and my last pregnancy caused my pubic bone to separate. I still, after 14 months, have incredible pain. However, I am thinking a little chub is better than feeling like crap!

Warning!
posted Dec 29th, 2011 1:31 amMy husband took this pill to loose a few pounds along with his work out plan. it made him crazy, he became very depressed and angry. He is a very optimistic person and always happy and in a good mood. Soon after he would take the pill each day he would get frustrated over the smallest things, he said he felt violent, sad, and like nothing could hurt him all at the same time. On days he wouldnt take the pill he would be back to his normal self even at night once the pill wore off he would be normal. It does curb your appetite but can be dangerous to people who have other health issues. (THIS IS A DRUG) Please use with caution!!!!

I have lost 10 pounds in 3 weeks. I am disabled and am not able to really work out. With Fastin I am finally losing weight. I have to lose weight for my health. I bought my Fastin at Walgreens for $20.00. I am off of soda, coffee, and do not crave sweets. My sweet tooth is finally under control. My thyroid Dr approved of me taking Fastin. After taking it for 3 weeks and losing 10 pounds my triglycerides have gone down almost 200 points.

Just started taking Fastin today. I'm 178.4 lbs and i'd like to be some where around 120 - 125 within six months. Hopefully I will reach my goal. I'll check back in a couple days.

BE WARNED. I took this pill and kick started myself into some seriously unhealthy habits. I got perfectly thin. But I also got seriously dependent. I felt so happy when I took it -- a false sense of well-being that made me downright foolish. I felt like nothing could hurt me...but the drug (and it is a DRUG honey) became like a deep need. My heart suffered, my personal life suffered, my health deteriorated. I'm guessing you're reading this and thinking it won't happen to you...well hear this -- I have never done any kind of drug. Never been dependent on alcohol or anything. I was a public school teacher, and ADDICTED to this thing. When people who love me begged me to get off I finally did and had terrible dizzy spells, fatigue that required me to lay down, and I gained weight. You will too. My husband made me promise to never touch the stuff again. Honestly, I don't know why it's legal when so many people get strung out on it and have heart attacks...and I wonder if they' husll even print this review. Danger people. Run away.

I was a Pink Lady in a hospital in Alabama back in the 80's. I noticed a lot of staff was losing weight like crazy so I asked one what was going on. She said that they were taking Fastin capsules.
posted Jul 1st, 2011 7:25 pmI asked my doctor, (staff also) if he would give me a Rx, he said "sure" and pulled a Rx pad from his pocket and gave me one for 1 month's supply, (with a verbal refusal for more, due to addiction possibility).
I had the prescription filled for $2.49 and took one the next morning... Life was GOOD!
I totally forgot about food! I cooked for my family, and ate what I wanted, I just didn't want food! Not even foods that I loved and salivated when I smelled them. I found out on the third day that I could skip a pill and not know the difference. I lost 30 lbs in two months because I stretched the pills out to one every two and sometimes three days. I OWNED MY WORLD! I had no problem sleeping; no shakes, no headaches, NOTHING!
I have pined for Fastin all these years since, like an old love! I knew they had been pulled from the market, and I had moved away from Alabama, but I will never forget my affair with Fastin. I'm 67 years old now and fat. I can't bring myself to ask my young whippersnapper doctor if I have another go with Fastin. I'm diabetic now and don't want to kick-out and leave my grandchildren because of a few pounds!

Went off of it for awhile because a sudden health problem. I have MS now. It causes horrid mind numbing fatigue. I take these pills now to combat the fatigue and they work great. Cleared it with my doc and I still have 45 pounds to go. Like the review said THIS IS NOT FOR PEOPLE LESS THAN 50 POUNDS OVERWEIGHT. This is very powerful and can mess with you if you are not truly fat. Dont be stupid on these pills. Only take them if you truly are ready for the side effects.

My Friend tried Fastin What she don't like about FASTIN is the 100mg of caffeine. It gives her a headache. So she switched to RVL it is all natural and contains 8 vegies. She had so much energy and felt good. She slept better at night and lost 20 lbs in 4 weeks. RVL is a nutrition shake and supplements for your health. Go to and read more about it. My friends have all lost more weight this time then any other diet pill.

Took my first pill about 30 - 45 minutes ago and suddenly feeling cold - slightly shakey but not like i have with other pills.
posted Mar 30th, 2011 10:08 amI dont need to lose weight per say but decided to try this pill since I have gained since last summer and I would like to lose what I gained (about 8 - 10 lbs).
I will likely take 1 pill every morning & see what happens.

Checking back in... I hate when people say they will do that and they dont. So here goes. I started at 219 and got down to 215 with the first box. Took a week off then got a second box. Just finished that box. Went from 215 to 211. Its a good pill but I think its starting to mess with my chemistry since I am on Byetta also. This is a diabetes medicine that is made of gila monster venom.... Well like I said before, this is not a pill to take if you want to lose 20 pounds or less. It makes you too woosey and lightheaded for it to be for the smaller people.

i liked it it dont really curve your appetite, but the energy is enzane, i felt untouchable wen i was on it and happy, i weighed around 240 pounds when i first started taking it and this was my first diet pill i have tooked instead of taking one in the morning and one in the afternoon i took two at once then started working out then when i felt tired i would take another one so i took three a day which probably wasnt to safe, i used about five bottles of it and i only dropped like 5 pounds so i was down 230 i stopped taking it becasue i started feeling addicted to it and i didint want to get to deep into it. then i took hydroxycut hardocre and didnt really lose anyweight but i was working out probably 6 to 8 hours a day so i was probably puttin on alot of muscle and buring fat. Then i changed my mind about losing weight, i just wanted to turn all my fat into muscle so then i stoped wanting to supress my appetite and dieting and just bulk up. Then my cousin terry told me about nitric oxide products and told about superpump 250 and jack 3d and i started to take them and i hadnt changed anything about my workout plan i just took it and workout nothing different and i started dropping pounds like crazy and was eating normaly i guess i worked out so much i built a high metabolism to burn fat off and lose wieght so i weigh about 190 now and am 6,1 and i lost all that weight without trying and when i was trying i couldnt lose any weight i guess it takes time

I started Fastin two weeks ago. What I have learned is that one pill in the am and then one pill at noon is just fine for me. Two pills in the morning....well it cleans you out in a very unpleasant way. It made me slightly lightheaded and happy. Kind of like when I take vicodin for migraines. Anyway, I really didnt notice any appetite loss per se. My stomach didnt growl as much, but I still ate the same. The reason I started this is because I have worked out everyday for 5 months straight (after 15 years of being lazy) and dropped 4 sizes but only one pound. I wanted the scale to budge. I already work out eat right and drink 6 liters of water a day. I just needed a slight kick. After two weeks I lost 6 pounds. I just bought another box and I plan on taking it til its gone then taking a week off. I'll keep doing that til I hit my goal weight. That is if I do not suffer any ill effects. I am diabetic and do not feel the need to kill myself. I do NOT think this pill is for anyone wanting to lose 20 pounds or less.
