Fastin was originally sold as a pharmaceutical diet pill with phentermine–an appetite-suppressant. But in 1998, this version of Fastin was withdrawn from the market by its maker, Smith Kline Beecham.
King Pharmaceuticals was the manufacturer/distributor of Fastin and no doubt did not want to lose what had become a valuable brand name. So they “reformulated” Fastin without phentermine.
Today, the main ingredient in Fastin is phenylethylamine, which is also found in the top-rated diet pill Phenphedrine.
The New Fastin Formula
It’s important to realize that the Fastin, which contained phentermine, is not the product you’ll see on store shelves today. Instead, it’s a diet pill owned by Hi-Tech Pharmaceuticals with completely different ingredients marketed under the same name.
Fastin has a 245 mg proprietary blend of these ingredients:
• Phenylethylamine HCL
• Methylphenylethylamine tartrate
• Methylsynephrine HCL
• N-Methyl-phenylethylamine HCL
• Synephrine HCL
• Theobromine Anhydrous
• Yohimbine HCL
Phenylethylamines–or the top 5 ingredients in Fastin–are related to amphetamines. They may increase extracellular levels of dopamine; helping to alleviate depression and promote feelings of pleasure. As for its application to weight loss, there is no direct connection.
Synephrine is a stimulant. In clinical studies, it was shown to increase the rate of fat metabolism, reduce hunger, and boost energy. Some people are skeptical of this ingredient, because it’s often compared to the banned ephedra. However, the studies I found show that it can work without causing serious side effects.
Theobromine is a bitter alkaloid of the cacao plant. It can act as a stimulant to boost metabolic functions, which may help the body burn more calories.
Yohimbe is known as an aphrodisiac and is often included in male enhancement products and diet pills. Some studies show that it promotes fat loss by inhibiting alpha 2 receptors. If uninhibited, these receptors could prevent your body from burning fat; especially if you’re dieting.
Caffeine Anhydrous (100 mg) is also an ingredient in Fastin, but it isn’t part of the proprietary blend. Studies show that this stimulant speeds up fat burn and increases energy.
Will Fastin Cause Side Effects?
Fastin’s formula is 100% stimulants, and not all of them are considered to be safe. So I think there is a chance that it could cause side effects.
If you’re sensitive to stimulants, you could experience jitteriness, sweating, increased heart rate and blood pressure, and insomnia while using Fastin. If you fit under the “sensitive” category, I recommend trying a milder diet pill than Fastin.
Yohimbe is considered to be “possibly unsafe” by WebMD.com. It has been linked to reports of kidney failure, rapid or irregular heartbeat, seizure, and heart attack. Products that use yohimbe typically have 10-20 mg. I’m not sure how much Fastin has.
I wasn’t able to find any customer reviews for Fastin, so I’m not sure if, or how often, users report side effects.
How to Use It
Each bottle of Fastin has 60 tablets and you’re supposed to take 2-3 a day. If you’re just starting to use Fastin, it would be best to only take 1-2 tablets a day. This will give your body a chance to adjust and it may help reduce initial side effects. You should never take more than 4 tablets a day.
Based on my research, I think the best time to take Fastin is before a meal or exercise. Always take it with water; and if you experience stomach upset, you may want to take it with a little food.
If you want to get the best results while using Fastin, I recommend combining it with a healthy, low-calorie diet and regular cardio exercise. This should help you burn fat faster and get results sooner.
The Cost & Guarantee
Fastin is not cheap. When you buy it from the official website, one bottle costs $89.95! And depending on how many tablets you take that bottle will only last for 20-30 days.
A 30-tablet bottle of Fastin is available for $29.99 on www.cvs.com. But considering that you’ll need 2 of these bottles to have a month supply, Fastin is still not very affordable.
I couldn’t find a retailer who offers a money back guarantee.
Is Fastin a Good Value?
If you can handle a powerful diet pill, I think Fastin could help you lose weight. But I’m hesitant to recommend it because it’s not completely safe and it only has a few clinically proven ingredients. Fastin is also very expensive and it doesn’t come guaranteed, so I’m not confident that you’ll get your money’s worth from it.
I feel more confident recommending Phenphedrine. It has several clinically proven ingredients and no harmful ingredients. Phenphedrine is very popular and it comes highly-recommended by users. It also costs less than Fastin and it’s backed by a 90-day 100% money back guarantee.
