Fastin XR

“The king of stimulant weight control formulations just got better,” says Hi-Tech Pharmaceuticals. Of course, they’re referring to the new-and-improved Fastin XR.

The original Fastin remains one of the most popular weight loss supplements available. And Fastin XR is promising to top that. Well, I was certainly intrigued. I decided to see if the new Fastin XR really is better.

Hopefully, my research helps you decide if Fastin XR is worth buying.

What Ingredients Does Fastin XR Use?

Fastin XR contains the same ingredients as Fastin, and then some. The caffeine dosage is larger. The proprietary blend is bigger. And Fastin XR is more powerful

Caffeine Anhydrous (150 mg) – There are 3 benefits from caffeine. First, it stimulates the body to burn calories faster. Second, caffeine reduces bloating from water retention because it’s a diuretic. Third, caffeine stimulates the central nervous system, which increases energy and alertness.[1]

Acacia Rigidula Extract – Researchers discovered this plant contains more than 40 alkaloids. Among the alkaloids are amphetamines, phenylethylamine, nicotine, and other psychoactive compounds. These substances don’t burn fat, but they may alter or improve mood. Unfortunately, researchers said some alkaloids in acacia are toxic.[2]

Synephrine HCI and Naringen – These stimulants are extracted from oranges and grapefruit. They increase energy and metabolism without raising heart rate or blood pressure. In one study, people taking synephrine burned 65 more calories. Combined, synephrine and naringen burned 129 calories.[3]

Theobromine – It’s an alkaloid derived from cocoa. Although conclusive evidence is lacking, many people believe theobromine improves insulin sensitivity. It may have mood-elevating properties, too.

Green Tea – Catechins are antioxidants found in green tea. They prevent oxidative stress and repair cell damage. Catechins also reduce body fat and improve cardiovascular health. Study participants significantly reduced their body weight, BMI, and body fat after taking green tea daily.[4] Caffeine is also found in green tea.

1,3-Dimethylamylamine (DMAA) – This is a powerful stimulant that–until recently–was used in many weight loss and workout supplements. In 2012, the FDA announced DMAA is synthetic and unsafe. They asked several major supplement companies to remove DMAA from their products.

5-Methoxytryptamine HCI – Because it’s related to serotonin and melatonin, this ingredient may improve mood and sleep quality. Serotonin also regulates appetite, so methoxytryptamine may suppress cravings. I was unable to find supporting research.

Yohimbine HCI – It’s best known for increasing libido, but yohimbine burns fat and increases blood flow, too. When athletes took yohimbine, their energy increased and physical performance improved.[5]

Are the Ingredients Safe?

The FDA was skeptical about DMAA years before they banned it. The final straw landed when 2 soldiers died after taking a supplement with DMAA.

Despite the FDA’s warning, Hi-Tech Pharmaceuticals continues selling Fastin XR with DMAA. But DMAA is not the only harmful ingredient. According to researchers, acacia rigidula contains toxic alkaloids with harmful potential. And WebMD.com says yohimbine may be dangerous. The ingredient is believed to have caused kidney failure, seizure, and heart attack.

There are a few ingredients in Fastin XR I’m not sure about. Mostly because, there isn’t any or enough research to prove they are safe.

Does Fastin XR Have the Right Dosages?

Each serving is 1 capsule. Take 1-2 capsules in the morning and 1 after lunch. If you take more than 4 capsules a day, the product label recommends contacting poison control immediately.

When you take 2-3 capsules, Fastin XR provides an effective caffeine dosage. I’m not sure what the other ingredient dosages are because the supplement uses a 375 mg proprietary blend. So, I can’t verify Fastin XR contains safe, effective amounts.

Fastin XR Reviews

Amazon.com has 16 reviews for Fastin XR. From these 16 users, the product received an average 4.3 out of 5 star rating. Users who liked Fastin XR said it burns fat and curbs appetite without causing side effects. They lost weight faster with less effort.

Three users weren’t thrilled with Fastin XR. Dani said the bottle label showed “90 capsules,” but there were only 45. Malisa experienced hot flashes and didn’t get results. Eke claimed Fastin XR impaired his mood and caused depression.

There are 7 reviews on LuckyVitamin.com. The average rating here is 4 out of 5 stars. Only 1 user gave Fastin XR less than 5 stars. All 7 users said Fastin XR works, but 1 user said her blood pressure increased significantly.

Hi-Tech Pharmaceutical Reviews

Since 1994, Hi-Tech Pharmaceuticals has made “high-quality herbal products.” They are a self-proclaimed “industry leader” in the supplement market.

Over the years, Hi-Tech has maintained a good reputation. In 1997, they were accredited by the Better Business Bureau. Currently, the company has an A+ rating.

Only 2 complaints were filed through the BBB in the last 3 years. Hi-Tech responded to both. I couldn’t find any complaints or scam reports on other sites.

Where Is Fastin XR Sold?

HiTechPharma.com (official website) features Fastin XR, but doesn’t sell it. The company sells their products at GNC, Rite Aid, Albertson’s, CVS, and Walgreens. You might find Fastin XR in these stores. Or you can buy it from these sites:

• Amazon.com: $51.99
• LuckyVitamin.com: $53.97

These are prices for 90-capsule bottles. Amazon.com also sells a 45-capsule bottle for $39.99.

Once you open Fastin XR, neither Amazon.com nor LuckyVitamin.com will accept returns.

Should You Try Fastin XR?

Fastin XR is made by a reliable company. The few user reviews I found were mostly positive. In addition, Fastin XR contains several clinically proven ingredients. These should burn fat, improve mood, and suppress appetite. But they may cause side effects, too. After researching the ingredients, I’m surprised more users didn’t report side effects.

Fastin XR contains 3 potentially unsafe ingredients. One was recently blacklisted by the FDA. Also, I can’t tell if safe, effective dosages are used. All in all, there are many safer supplements with more proven ingredients available.

I feel energized, alert, and not hungry! I do not feel any side effects other then loss of appetite. When I eat I eat a lot less and I don’t have the cravings for carbs I usually do. I have been eating Paleo and working out almost everyday and have lost 29lbs in 6 weeks. Fastin has helped me achieve this BUT it is not a magic fix, you have to do the work, Fastin just makes it a good deal easier!

Yes, I recommend this product

It did push me during workouts and made me feel quite a bit less hungry but most of that was from being horribly nauseas off it with bad headaches. It was like having the stomach flu & I have taken many diet pills & NEVER felt this horrible. Plus they taste disgusting. Will definitely stick to Ab Cuts or hcg drops…will not even finish this barely used bottle I purchased.

No, I do not recommend this product

Fastin XR

I am a pretty small person 119 lbs and am very sensitive to these types of products. Most make me jittery and just feel gross after about an hour of so after taking them. This product, however, did not do that. I got the benefits of excelled energy and appetite suppressant without the neg side effects. Good Product.
