For Weight Loss (Obesity/Overweight) "I just started using Fastin and I like it better than other diet pills I've tried, such as Hydroxycut, because it doesn't make me feel sick or nauseous. However, it definitely makes my heart rate skyrocket, so for the first couple of days, I would only take half a pill at a time. A full pill makes my hands tremble, and I can hear my pulse in my brain."

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

For Weight Loss (Obesity/Overweight) "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."

For Weight Loss (Obesity/Overweight) "I tried Fastin for the first time today, which I purchased over the counter. Within 20 minutes, I experienced a slight euphoric feeling. After 30 minutes, however, my heart started racing, my body and hands began shaking, and I felt as though I was going to pass out when standing. I had to sit down until I felt in control. After 45-50 minutes, the shakiness and racing heart improved, as well as the dizziness when standing, but didn't disappear completely for over an hour. My mood still remained lifted. I may just be sensitive to the initial dosage, so I recommend that anyone sensitive to stimulant medications begin with a half dosage to minimize the initial negative effects until your body gets used to the drug."

For Weight Loss (Obesity/Overweight) "I used to take Fastin/Fastin XR in 2012. Within a few short months, I went from a size 9/10 to a 4. I kept the weight off for 3 years after stopping this product. I’m only 5’3″, so all the extra weight on me was really noticeable. I didn’t like the side effects at all: shaking, racing heart…but it definitely worked. I just started taking this product again a few days ago because I’ve gained 35+ lbs within 4 months due to major lifestyle changes. I’m trying to get back on track again. Hopefully, I’ll get similar results this time around too."

For Weight Loss (Obesity/Overweight) "I heard from a lady I work with about Fastin, and she told me it worked well for her. So I came on this site and read the reviews. I was concerned with a lot of reviews stating that there were side effects such as pounding/racing heart and jitters. Despite the reviews, I still ordered the pills. After receiving the pills, I still waited a few days before starting because I was terrified of the side effects. So I finally started taking the pills a week ago. I started taking just half a pill in the morning and half after lunch, like recommended in a review I read. After a couple of days, I began taking a whole pill after breakfast and a whole after lunch. I have had no side effects at all and have lost 5 lbs in 1 week."

For Weight Loss (Obesity/Overweight) "I was prescribed Fastin for weight loss. 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 the office only. So every month it was $40 for the doctor visit and weigh-in, and another $40 for 1 month's 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-caffeinated crap! I had gotten very ill halfway into taking the first bottle and had to stop because of jitters, headache, paranoia, racing heart!!! My advice, pay for the real stuff."

For Weight Loss (Obesity/Overweight) "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."

For Weight Loss (Obesity/Overweight) "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 heart rate and slightly the jitters. To be honest, I haven't seen much of a weight loss. 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 35 lbs, so that there is inspiring me to push forward to achieve my weight loss goal."

For Weight Loss (Obesity/Overweight) "Terrible! Terrifying! Don't take Fastin! I took a whole tablet, and within 15 minutes, my heart was pounding out of my chest. It was so bad that I could see my shirt moving with every heartbeat. If you are prone to panic attacks, this will make your heart race even more. My heart rate finally slowed after 1.5 hours, and then I had chills and jitters. I took this drug because my doctor wouldn't give me RX medication for weight loss."
