Fastin-XR Review - Does This Weight-Loss Supplement Work? Are side effects and ineffectiveness deal breakers?
We’re hearing a lot of buzz about Fastin-XR, so we dove deep into the ingredients, side effects, customer service and clinical research. We collected comments from hundreds of user reviews and statements. Then, we gathered, condensed and summarized to give you the info you need.
What is Fastin-XR?
First off, Fastin-XR is a weight-loss supplement that contains caffeine, 1,3 dimethylamylamine, methylsynephrine and two forms of phenylethylamine.  You take up to three capsules a day and that’s supposed to boost energy and help you lose weight. You’ll have no trouble taking this one with you, a good thing.
The product, introduced by Hi-Tech Pharmaceuticals after the company started in 1993, lists some of the ingredients online, a positive. We like that some customers report results and the BBB rating is an “A-“, but read on…
Fastin-XR Side Effects – “A Major Issue?”
The first issue deals with Fastin-XR side effects. We found more than a few reports of dieters noticing significantly negative changes after taking the supplement. “There are a few ingredients in the formula with some clinical support,” explains our Research Editor. “But, the user has to take into consideration the parts that may cause problems as they take precedence over any positive.”
“I was very positive when purchasing this based on the reviews but when I took 1 tablet, my heart was racing. I thought it would jump out of m throat! I then tried 1/2 tablet and still the same result,” explains a dieter.
“I tried a whole tab and I thought my heart rate was way too fast,” says a user.
Another describes something different, “It made my heart race, but I realized I was taking too many. Cut down to one and I was okay.”
FDA Action – “What’s That About?”
Hi-Tech Pharmaceuticals has been the subject of multiple FDA investigations. The latest letter was sent to the company in April 2015. According to the communication, several products, including Fastin-XR were mislabeled. They were told to stop selling all supplements claiming acacia rigidula was a source of Beta-methylphenethylamine. We checked the official website and it appears they have complied with the order.
Ineffectiveness – “Not Effective?”
Hi-Tech Pharmaceuticals claims the supplement is the “strongest and most technologically advanced diet aid ever developed.” That’s some pretty big shoes to fill, considering Fastin-XR ingredients may not be effective. “After giving the product a full month I found it pretty worthless,” offers one user.
“I am a trainer therefore I know what it takes to lose weight, I am not one of those people who expect a miracle pill, however i have not shed 1 pound,” says a consumer.
A disappointed dieter explains, “I have been on this for 30 days and have been watching my intake. I haven’t lost a pound, in fact I gained a couple. I do not recommend this product, I am going to try something else.”
We found that some Fastin-XR reviews offered another side of the story. “Jump starts the energy, but nothing too terribly bad,” said a customer.
“No negative side effects so far,” offered another.
Based on our research, it takes one thing, like side effects, to ruin your chances of long-term success. If Fastin-XR causes jitters and shakes, among other reactions, the dieter may well stop taking it within a few days.
The Science – “Where’s the Proof?”
All you get from Hi-Tech Pharmaceuticals is a long description packed with product claims. We didn’t find a single reference to clinical studies. We were able to locate research supporting caffeine as a metabolism-booster, but it didn’t point toward this formula. Both synephrine and 1,3 dimethylamylamine are associated with some pretty harsh side effects like increased heart rate and increased blood pressure. The fine print for Fastin-XR does say it can cause issues with BP and it may interact with medications.
The Bottom Line – Does Fastin-XR Work?
So, what’s the final word on this one? We were quite interested in taking a closer look at Fastin-XR. The supplement does offer a decent price and Hi-Tech Pharmaceuticals has been around for more than 20 years, but we have some reservations about supporting a product that potentially causes side effects with ingredients that are not clinically proven. We’re also concerned with the FDA’s interest in the company and the fact that they are currently involved in a lawsuit with the FTC.
If now is your time to lose weight, we suggest going with a supplement that gives you clinically proven ingredients that’s not in the cross hairs of any government agency. It is a huge benefit if there are no side effects, either.
Among the best products we’ve seen in 2016 is one called Leptigen. The formula consists of four ingredients in a proprietary blend supported by clinical research showing it helps boost fat loss and spark metabolism. We’ve not found a single dieter talking about adverse side effects, but we found plenty telling others about seeing great results.
Also, the company that makes Leptigen is confident in the product so they’re offering a Special Trial Offer, a rarity.

Advantages of Fastin-XR

- Fastin-XR requires no prescription.
- This diet product contains antioxidants to fight free radical damage.
Disadvantages of Fastin-XR

- The stimulants in this weight loss pill might lead to side effects.
- There is no guarantee available with this dietary supplement.
Fastin-XR ConclusionThere are plenty of diet pills and weight loss products that are loaded down with stimulants. Fastin-XR is no exception. After all, this supplement contains four types of stimulants, in addition to Synephrine. Synephrine is basically an alternative to Ephedra, and it causes similar effects. Therefore it may also lead to similar side effects, which can be dangerous. Therefore we do not recommend Fastin-XR for safe weight loss. Not to mention the high price of this diet pill. $80 is a lot to spend on a dietary supplement; especially when there are so many others available for much less money.

Fastin-XR Ingredients and Supplement Facts

Other Ingredients: None
We took a close look at Fastin-XR ingredients to give you the facts.
Acacia Rigidula Extract
Sometimes called blackbrush acacia or vachellia rigidula, acacia rigidula extract comes from a type of shrub. It grows in regions like Texas and certain parts of Mexico.
What is it Supposed to Do?
Well, acacia rigidula contains amines and alkaloids. These include hordenine, catechin, nicotine, phenethylaimine, tyramine, and tryptamine. Together these components are supposed to help suppress appetite and increase metabolism. This in turn helps with weight-loss.
According to the FDA, “Products whose labels claim to contain Acacia rigidula are commonly marketed for weight loss, supposedly by suppressing appetite and burning fat. But 9 of the 21 dietary supplements tested were found to have an unnatural compound, called beta-methylphenethylamine, which is structurally similar to amphetamine.”
There have been some clinical studies done with acacia rigidula. According to WebMD, “Acacia rigidula contains many different chemicals that have stimulant effects. Because of this, it is often promoted for weight loss and athletic performance.” However, it goes on to say that there is insufficient evidence to support this ingredient for weight-loss.
Clinical testing is an important part of the equation when it comes to choosing a diet supplement. You may want to take a look at a product like Leptigen. It contains some ingredients that have been researched.
First off, isopropylnorsynephrine is a lipolytic agent. It’s similar to synephrine, which is found in citrus aurantium or bitter orange fruit. It is also known as betaphrine or isopropyloctopamine.
What is it Supposed to Do?
The purpose of isopropylnorsynephrine is to boost metabolism, increase energy levels, reduce appetite and enhance focus. It’s often combined with other stimulants and herbs to help promote weight-loss.
According to the National Institutes of Health, “Isopropylnorsynephrine is a stronger lipolytic agent in human adipocytes than synephrine and other amines present in Citrus aurantium.” One study showed that this ingredient might be useful for weight-loss. However, clinical trials involving human subjects are needed.
If you eat chocolate, then you’ve had theobromine. It’s actually the principle alkaloid in the cacao bean. Also called xantheose, this substance is a stimulant and diuretic.
What is it Supposed to Do?
Since theobromine is a mild stimulant, it can help keep you alert and boost energy levels. It may also help suppress appetite to some degree, and even elevate mood. There are also some claims that it aids with weight-loss.
One 2005 study from the American Journal of Clinical Nutrition said, “Healthy participants were given dark chocolate — which contain high amounts of theobromine — for 15 days, and then switched to white chocolate, which contains none. Researchers found that dark chocolate significantly improved insulin sensitivity, which is an important aid in controlling body weight.” Therefore this ingredient may help with weight management on some level.
Is There Anything Out There That We Think TRULY Works?
We have our eye on a supplement that fits the bill. Leptigen, which is formulated with ingredients that HAVE been clinically tested, may be a good option. All customers can take advantage of a Special Trial Offer, currently available. Click here to give it a try.
