Best Fastin Alternative

Due to all the negative reviews about Fastin, we’ve been looking for a competitive product that was proven more effective. We checked several of them with deception, and finally came around a real effective weight loss supplement. You can read its review HERE.

Who Should Take Fastin?

This supplement is not for use by persons who are below 18 years old or if you are pregnant and/or nursing. It’s also indicated that the product can cause high blood pressure or affect other drugs that you are taking. Consult with a doctor first before using, especially if you are hypertensive or on medication.

Serious adverse reactions may also affect individuals who are:

  • regularly consuming caffeine
  • taking medications or dietary products that contain caffeine or synephrine (ie soda, tea, coffee, etc)
  • taking medications that contain ephedrine, pseudo-ephedrine, phenylephrine, and other types of stimulants

How Does Fastin Work?

The formula of this diet pill is based on its main active ingredient which is Phenylethylamine alkaloids that they derive from acacia rigidula. Phenylethylamine is a chemical that may be taken to improve attention, athletic performance, and mood. It can also affect weight loss.

As PEA is activated, it prompts the brain to amplify the effectiveness and signal strength of the brain’s major neurotransmitters. As a result, the following mental functions are enhanced:

  • well-being
  • pleasurable feeling
  • wakefulness
  • mental activity
  • memory
  • impulse control
  • emotion
  • mood
  • social activity
  • physical drive
  • motivation

The other active components of Fastin act mainly as stimulants, thus contributing to weight loss. While it may have the ability to help you lose weight fast, it is also not something that’s recommended for long-term use.

Fastin Ingredients

There is a proprietary blend used for the formula of Fastin, and it includes the following ingredients:

Phenylethylamine HCI – PEA works by stimulating the body so that it can produce chemicals that greatly help with the treatment of various psychiatric conditions such as depression.

It is worth mentioning though that too much PEA can bring side effects that are similar to that of amphetamine. Side effects like agitation, anxiety, and rapid heart rate may occur. People with bipolar disorder who would use this substance can also be negatively affected as it can shift from depression to mania.

Methylxanthine HCI – The main source of this ingredient is bitter orange or citrus aurantium. This is a very popular weight loss ingredient that manufacturers use in place of ephedra, especially after ephedra was banned. This thermogenic compound can promote metabolism but can also elevate heart rate.

Theobromine anhydrousTheobromine is another stimulant that typically occurs in cacao, which is the main ingredient in chocolates. It can keep you more awake, energized, alert, and refreshed. The effects are somewhat similar to that of chocolates but eating large amounts of it may also lead to weight gain.

2-Aminoisoheptane HCI – This ingredient helps you in controlling your appetite, while also allowing you to achieve your bodybuilding goals. It elevates the levels of focus and energy. However, it can also lead to several side effects like increased heart rate, shortness of breath and high blood pressure.

Other ingredients that you can find in this supplement are Caffeine Anhydrous, Yohimbine HCI, Synephrine HCI, and N-Methyl-B-Phenylethylamine HCI.

Fastin Side Effects

Basing on the reported cases, there are several side effects that may occur when taking Fastin. Take a look at this list:

  • anorectic effect or the feeling of completely losing your appetite
  • rapid heart rate or tachycardia
  • high blood pressure
  • cardiac arrest
  • palpitations
  • regurgitant cardiac valvular disease
  • myocardial infarction
  • angina
  • severe jitters
  • difficulty in sleeping
  • blurred vision
  • trembling

As you can see, the side effects can become quite serious. That’s why it’s best to talk to a healthcare professional first if you plan on taking this supplement.

Fastin Dosage

For the dosage, you may take 1 to 2 Fastin tablets in the morning, and then another tablet after eating lunch. Make sure not to exceed a maximum of 4 tablets per day.

It is also a supplement that can only be taken short-term. The ideal term is 8 weeks only. If you are about to undergo a surgery, discontinue use at least 2 weeks before.

Fastin Reviews

Unfortunately, there are no Fastin reviews that are reliable enough on the Internet. When we say “reliable enough”, that means that they come from independent and verified users who have tried the product.

The only reviews we found so far are those that are posted on their official website.

Where To Buy Fastin?

This is another drawback of this supplement. It is currently unavailable on their manufacturer’s site due to stock issues. There is also no Amazon listing for it at the moment.

We’re not sure if you can find this product in local drug stores and other authorized retailers that they have included on their list of distributors.


Does Fastin Really Work Or Is It A Scam?

So far, we cannot tell for sure if Fastin can really work or not. Although weight loss supplements are becoming more and more widespread these days, it’s surprising that this product does not have any independent reviews that we can use as a reference.

There are actually other diet pills in the market that you can choose from and are guaranteed to work if you are to read over the reviews about it. Make sure to know your options well enough first before finally picking the right supplement that you think can greatly help you out.
