"When I started taking this medicine in December along with Metformin and Simvastin I lost 66 lbs. I started at 306lbs and now I weigh 240lbs. I am unsure if the drug is having any effect on me any longer - I will know when I see my doctor again. Perhaps I am just at a wall for the time being. Anyhow I think it works great."

"So the first tiime i took half a pill I had no side effects. However, the second time I took 1/2 with an empty stomach and I had to go to the hospital. My heart was racing and I couldn't breath the pain in my chest scared the shit out of me enough to stop using it all together."

"After suffering from bulimia for many years and not being able to control my binge eating I started taking Fastin. I only take 1 1/2 pills a day (I'm only 115 lbs and not looking for significant weight loss) and that is enough to help me fight my urge to stress eat. In fact when I was taking 2 pills a day I found myself forgetting to eat. I still feel a little jittery after taking them. "

"I was prescribed Fastin for weightloss . The prescription pills worked great not a single bad side effect I lost over 50 lbs in about 4 months. It gave me energy to start working out and WOW did my concentration for work improve . However the pills were costly and given out in office only. So every month it was 40 for the Dr visit and weigh in and another 40 for 1 months worth of pills . When I was unable to afford this regimen I looked for cheaper alternatives. I got some over the counter bottle of FASTIN I bought 2 bottles. These are unhealthy, way over caffinated Crap! I had gotton very ill half way in to taking the first bottle and had to stop bcaz jitters, headache, paranoia racing heart !!! My advise pay for the real stuff."

"I was stuck at the same weight for over 2 weeks. I was working out over 60 min a day. I decided to try Fastin and within days started losing weight again. I have been taking it for 5 weeks and have lost 10 lbs. That's good enough to get my approval. It really helps me not be hungry throughout the day. And gives a noticeable increase in energy. I have noticed some jitteriness about 1 hr after taking it. But it does not last long and to me is worth the weight loss."

"Fastin is a good appetite suppressant. When first taking it there are side effects of heart beat increases and jitteriness. That goes away after a few days. Fastin seems different than other diet pills in that I don't seem to eat the missed calories at night when the meds wear off. Definitely have to move/get active and drink plenty of no calorie drinks to lose the weight. I'm 49 and have used Fastin on and off over the last 20 years. I've had period of 60 lbs lost, then I stop paying attention and gain some/all back, especially now at that time in my life when all women have a hard time losing weight. I'm back on the down slide. I don't weigh myself but rather am enjoying the change in how my clothes feel."

"Fastin is really a great appetite suppressant! I have taken it for a few days. Yes it does make you jittery and your heart rate is increased but for me it wasn’t overwhelming. Unfortunately the only reason I couldn’t give it a 10 is because I do feel nauseous throughout the day which makes me not want to eat any food and drink tons of water !"

"Use with caution! I was stupid enough to take a whole pill and I thought I was going to die. My heart was racing even though I was laying perfectly still and the world was swimming like I was drunk. The effects have lessened over the course of a few hours but I will definitely not take more than 1/4 of one of theses pills in the future!"

"I don't know if I got a potent batch, but omg!!!! I lost 4 pounds in 1 week. I started out at 125 lbs in 2009 and I began taking creatine to gain weight (so not a good idea, if your not working out) I then blew up an landed at 160 lbs. I did everything I could to lose weight (supplement wise). About 2 years ago I started to hit the gym like really hard, and I changed my diet (no sodas, no processed foods, I drink 1 gallon of water everyday). I mean I changed my lifestyle. Now I weight in at 130 lbs!!! I'm so proud of myself (pats herself on the back), but honestly the beginning of week 10/26/15 I weighed in at 134 lbs and now I am at 130 lbs. 4 pounds in 4 days???!!! Thank for the BOOST FASTIN!!!"

"I made it through 3 days and discarded the bottle. I read the reviews and took the advise of most to only do a half pill. I am glad I did as the effects from just a half pill was enough to scare me. Within about 15 minutes it felt like my heart was going to explode out of my chest. This lasted about 30 minutes then it calmed down to a less fearful level. I felt pretty jittery and certainly like I was on "something" for several hours. I took a 1/2 table twice a day, ate first so to lessen the side effects. By day three and again my heart just going nuts, and thinking how silly this will be if I have to go to the hospital, I said no more. Threw away the bottle. It will be easier to just not eat ice cream at midnight! :-)"

"Got these pills and took a pill after breakfast and my heart felt like if it was going to pop out of my chest. Increased heart rate , blood pressure. Also gave me terrible headache and nausea. Felt like I was going to die. Had to go to hospital and the doctor told me I was getting an anxiety attack as well . Would not recommend it. Terrible experience."

"I suffer from obsessive compulsive personality disorder. It makes me not want to be around other people so I stay in all the time, which leads to extreme lethargy. I just lay in bed all day and spiral downward until I have no energy to do anything at all. Fastin gives me the energy psychologically as well as physically to get out of bed and start doing things. It does cause some side effects, but these are to be expected with something that works so powerfully. Only this or Zoloft have helped me to lead a productive life. With doctors for zoloft, I have to make appointments, pay for insurance, a doctor visit, the prescription, and wait in line at the pharmacy, none of which I can do after I run out of medication. Thank you Fastin"

"So I finally got the nerve to try Fastin. I started with only half a dose and I felt my pulse get a little higher but that was it. What surprised me is that it definitely works as an appetite suppressant and clearly curbs your appetite. If taken carefully you will see success. I will post more with later results. God Bless..."

"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"

"I lost 10 pounds in one month w this. not only that, I work ALOT and this is what keeps me going. I take one in the morning first thing then lay in bed and in about 5 min I feel ready to get up instead of wanting to stay in bed all day. and it's definately cheaper than going to the weight loss clinic every month!"

"This pill is the devil!! Don't do it!!!! I have seriously considered contacting the FDA to have it removed from the shelves! Made me feel completely out of control of my body and sick to my stomach to the point I had to lay down and hope I wasn't having a heart attack! Don't buy this crap!!"

"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."

"I have had no side effects whatsoever. It never sped my heart up or gave me jitters at all. I have lost about 3 lbs but I've only been on it a week. I would probably have lost more I have had to only do the stationary bike and swimming due to a sore hip. I will review again later"

"I've only been taking fastin XR for 3 days so I can't report weight loss yet. But so far I love this stuff!!! Total energy, alertness, appetite suppression. I don't take the full dose of pill at a time. So far I've only needed one pill per day, I break them open and spread it over 5-6 doses. That way the dose isn't too intense. I'm a person who snacks all day and taking this I'm really not hungry. I eat when I get a little weak so I know I need food but I don't get true hunger pangs. Also I normally sleep about 10 hrs a night. I've only needed 4-6 hrs of sleep each night and wake up totally alert. I have no doubt I will reach my goal weight using this!"

"Made me super sick. This was my first time trying it, I took the prescribed dose, and I've been trembling out of my skin for the last hour. My blood pressure is through the roof and my heart rate is 141 bpm right now. I'm also nauseous and would be at the emergency room right now if not so terrified I'd crash my car if I tried to drive."

"It works well at giving you energy, but it gives the jitters sometimes. It definitely curbs the appetite, but can also make you a little queasy. I lost weight with it, but stopped taking it after about 6 months."
