Fastin Overview

Fastin is a weight loss pill made to provide stimulant effects that are fast yet smooth and meant to produce a good feeling effect. It’s made for both men and women who need to lose stubborn fat.

There’s the claimed effect of it causing a stimulant effect, without any risk of jitters or side effects. There are currently 4 different styles of Fastin, but the main one is said to be for general purpose use. So is this actually a safe and effective approach to weight loss? What kind of stimulant effects might one expect? In this comprehensive review, all the important details about Fastin will be covered.

It may also trigger side effects that include:

“Methylsynephrine is a substance that does not meet the statutory definition of a dietary ingredient”

The FDA also sent warning letters to companies using this brand. They required them to stop using it, and to send them a notice that they have taken the steps to remove it from supplements.

Sporting organizations have also banned this ingredient’s use.

Theobromine Anhydrous: A dehydrated form of the stimulant theobromine. This stimulant is found in foods such as chocolate and teas.

It stimulates the heart, widens blood vessels, and has diuretic effects.

This ingredient can cause poisoning in high amounts. It may also produce side effects that include:

  • Vomiting, nausea, and diarrhea.
  • Seizures, internal bleeding, and even death.
  • 1, 3- Dimethylamine HCI: Stimulant that is similar in structure to Ephedrine, which is now banned in the US.

The FDA has warned against the use of this ingredient:

“consumers should not buy or use any dietary supplement product containing DMAA”

“FDA has received 86 reports of adverse events”

People have even died from using this additive.

Synephrine HCI: A stimulant sold under the name bitter orange. This ingredient is used to help burn fat. It affects the central nervous system and raises blood pressure.

Web MD mentions that this ingredient is:

“POSSIBLY UNSAFE when taken as a supplement for a medical purpose such as weight loss”

It may potentially cause side effects that include:

High blood pressure, fainting, and agitation.
Migraine headaches, ringing in the ears, and even death.
Certain people may also have an adverse allergic reaction.

  • Nausea, stomach bloating, and vomiting.
  • Rapid heart rate, tremors, and muscle spasms.
  • Stroke, heart attack, and even death.

  • Caffeine Anhydrous: Common stimulant found in foods that are dehydrated in order to blend better in a pill. It’s used to increase energy and focus, as well as metabolism.

There’s a total of 100 mg per serving, which means that a full serving provides 400 mg. This is considered the safe maximum amount allowed to experience effects without harsh side effects.

In certain people, much is needed for an effect. This ingredient may potentially cause side effects that include:

  • Insomnia, restlessness, and fatigue.
  • Rapid heart rate, agitation, and cardiovascular-related problems.
  • Anxiety, mood swings, and depression.
  • Vomiting, nausea, and bloating.
  • Caffeine when mixed alongside other stimulants may increase the overall risk for side effects.

Fastin Quality Of Ingredients

This brand relies heavily on stimulants in order to produce an effect. Unfortunately, there’s both DMAA, and methyl synephrine which have been banned by the FDA. These additives have been advised to be not taken due to their high rate of potentially serious side effects. People have died from using these ingredients on their own, when mixed alongside other stimulants, it’s unknown what kind of an effect it may have.

No clinical studies are available to show what will happen when one mixes all these stimulants together. Some people have even died from the use of these ingredients.

Stimulants are also not a long-lasting weight loss solution. They often require cycling and avoid use during certain periods in order to avoid insomnia, restlessness, and tolerance.

The Price And Quality Of Fastin

Sales are offered directly from the manufacturers. A full 15-day serving sells for $49.95. This means that a daily serving costs $3.33. No money-back return policy is offered.

Since this supplement contains 2 banned ingredients which the FDA has highly advised for people to avoid, this isn’t a particularly safe supplement. Studies have shown that ingredients in this may cause unwanted side effects.

There’s also a full 400 mg of caffeine when taken at the maximum dosage strength. When mixed alongside the other stimulant compounds, it’s unknown what kind of an effect this may have. It may potentially cause devastating symptoms. The FDA has even confirmed that people have died from the 2 banned ingredients.

It’s for all these reasons that this is a potentially dangerous supplement.

Business Of Fastin

The company is owned by Hi Tech Pharmaceuticals. Their customer service contact information is:

Phone Number: (800) 310-9108

Address: 6016 Unity Dr Ste B

Norcross, Georgia 30071

The company has had many issues with the FDA as well as the FTC.

The FDA sent them a warning letter about the use of BMPEA in Fastin. They mentioned that this ingredient is not only potentially unsafe but that it’s not approved for use in a supplement.

They add that the company should provide proof as to why they think it is safe, though it’s unknown if the company responded back.

Fastin was also once banned by the FDA, since the FDA concluded that the added DMAA was potentially unsafe. The FDA also had to schedule a seizing of the company’s brands by taking away their supplements. The FDA notice states:

“U.S Marshalls seized more than 1,5000 cases of finished goods… form the Hi-Tech Pharmaceuticals , Inc. . facility”

The FTC also filed a $40 million dollar lawsuit against the company for making unproven health claims about their supplements.

The FTC is still trying to pursue more legal claims against Hi Tech Pharmaceuticals.

Customer Opinions Of Fastin

Here are some customer reviews from websites:

“I had to go to the hospital. My heart was racing and I couldn’t breathe”

“I was on my way to the hospital with Tachycardia”

“I felt pretty jittery and certainly like I was on “something”

“Hated the side effects”

Many side effects that are often seen in heavy stimulant formulas have been seen. There were also a few cases of people having to go to the hospital.

The kinds of side effects seen include insomnia, rapid heart rate, anxiety, jitters, musce spasms, uncontrollable body movements, agitation, tightening in the chest, and difficulty breathing.

Those who experienced side effects state that they took either one pill, or half a pill.

I like Noom for its virtual coaching features and educational content. Yes, it’s a dieting app, but if you commit to using Noom to its total capacity, then you’ll get more than just weight loss. All in all, Noom is a potentially healthful app, but it will only work if you stick with it. Ultimately it’s still on you to commit to healthy living; Noom can only do so much.

The Mayo Clinic Diet is a balanced meal plan focused on fruits, vegetables, whole grains, and healthy fats. You’re meant to cook your own meals from scratch and exercise daily.

The diet possibly aids weight loss, but no comprehensive studies exist.

While it does not require you to count calories, it recommends servings of various food groups based on a target calorie level.

If you’re looking for a diet that you can maintain for life, the Mayo Clinic Diet is a balanced option.

The Ornish Diet is a low-fat, lacto-ovo-vegetarian diet that claims to offer substantial health benefits.

In addition to being flexible and easy to follow, some studies suggest that the Ornish Diet may help increase weight loss and protect against chronic disease.

However, it’s also very low in healthy fats and may lack certain vitamins and minerals, which can increase your risk of nutritional deficiencies.

Thus, if you want to give the Ornish Diet a try, be sure to plan it carefully to avoid negative health effects.

*Please keep in mind that with any diet or weight loss program, individual results will vary.
