FenMax Product Review

FenMax is a fairly new dietary supplement that is quickly gaining popularity on Amazon. The manufacturer makes many claims about this product’s ability to help you lose weight, but can it live up to the hype?

In this in-depth review, we’ll take a look at FenMax’s manufacturer and ingredients to see how well it can work. We’ll also let you know about any possible side effects.

FenMax Purpose

FenMax is a dietary supplement that helps you lose weight by suppressing your appetite and increasing your fat-burning metabolism.

Who Makes FenMax?

Researching FenMax proved to be problematic from the very beginning. There is no manufacturer listed on the product label. Additionally, there is no official product page beyond its Amazon sales page.

This is a problem, because although the product label states that this diet pill is made in an FDA certified facility following Good Manufacturing Processes, there is no way to verify this. Additionally, there’s no way to tell where the ingredients are sourced from.

How to Take FenMax

For best results, you should take one FenMax pill twice per day. The product’s sales page also states that FenMax is designed to be used while following an aggressive prescription-level diet and exercise program.


FenMax makes a lot of weight loss claims. The first claim is of course weight loss. The product page claims that taking FenMax gives you an energy boost that results in an increase your metabolism and therefore more effective fat burning. It also claims that this product can suppress your appetite. FenMax is supposedly safe to take over the long-term with little to no side effects. But can the product really live up to these claims?


Any time a product attempts to hide its manufacturer, it is cause for concern. There’s no way to verify where this product is coming from, and therefore it’s impossible to tell that the company producing this herbal supplement is reliable or truthful.

This product makes a lot of claims about helping you lose weight, but it also states that it should be used while following an “aggressive prescription diet.” The problems with this is that these types of diets are also intended to help you lose weight quickly. There’s no way to tell whether the results anyone achieves is a result of the ingredients in FenMax or as a result of the drastic lifestyle change following an aggressive prescription diet brings about.

When a product states outright that a product is safe to be used for the long-term, we become suspicious. After all, if the product helps you lose weight so quickly, why would you need to use this product long term? This can sometimes indicate that the product contains ingredients that may lead to dependency.


FenMax contains a proprietary blend of pharmaceutical-grade ingredients intended to help you lose weight.

2-Phenylethylamine – this ingredient is also known as PEA. It’s a neuromodulator that causes the brain to release “feel good” chemicals like dopamine and norepinephrine. Many antidepressants contain this ingredient. PEA is believed to help reduce emotional eating. It can also create a rise in blood pressure and blood glucose levels, which leads many to believe that it functions as an appetite suppressant and boosts the metabolism. Unfortunately, this also means that it can cause a number of unpleasant side effects. These include anxiety, racing heartbeat, nervousness, and insomnia. Additionally, because it releases chemicals that lift the mood and help you feel good, this ingredient can be addictive when taken over long periods of time.

Hordenine Hydrochloride – Hordenine HCL is a natural monoamine oxidase inhibitor. It helps to ensure that plenty of the neurotransmitter and “feel good” chemical dopamine is available in the brain. This means that it can help balance your mood, provide you with more focus and energy. Unfortunately when taken too much, too often, or for too long it can be responsible for chemical imbalances in the brain that can lead to mental health problems such as depression. It may carry other side effects such as dizziness, restlessness, anxiety, stomach upset, and rapid heartbeat.

Yohimbine Hydrochloride – this ingredient helps to increase blood flow throughout the body. This is believed to help increase your body’s metabolism. As you might expect, this ingredient also comes with a list of unpleasant side effects, including upset stomach, anxiety, nervousness, muscle tremors, insomnia, dizziness, irritability, nausea, diarrhea, bloating, and high blood pressure.

Synephrine Hydrochloride – synephrine is an analog for ephedrine, a now-banned chemical that was once very popular in diet pills. Synephrine is believed to mimic the effects of ephedrine, though with less potency. It’s believed to function as an appetite suppressant and energy booster. As you might expect and as is true of most stimulants, synephrine does have several negative side effects including racing heartbeat, anxiety, sweating, insomnia, and high blood pressure. If mixed with other stimulants, synephrine can even be dangerous.


We can find no positive reasons to take FenMax, in spite of the pharmaceutical grade ingredients this product claims to have.


There are a number of negatives associated with this product’s ingredients. The first of these is the fact that several of the ingredients on this product’s label can be addictive when used over longer periods of time. The second is the negative side effects associated with this product. Synephrine can even be dangerous when used alongside other stimulants like caffeine. When you add to this the fact that there’s no way to research who makes FenMax, we are left concerned.

Customer Reviews

When looking over the most recent customer reviews on Amazon for FenMax, it quickly becomes clear this product does not work. Only one of the top five reviews states that the customer had a positive experience. Additionally a few of the most recent reviews state they experienced unpleasant side effects such as nervousness and anxiety.

Verdict – Rejected

We can think of no good reason why anyone would want to take FenMax. There are certainly better products on the market today. Not only to the majority of recent reviews state that this product doesn’t work, the ingredient list is quite concerning. Add to that the fact that we cannot find any information about the manufacturer, and we recommend looking elsewhere for a diet pill that will work for you.

PhenTabz Review

It is an over-the-counter weight loss pill that is designed to aid in rapid weight loss while suppressing appetite and boosting metabolism. PhenTabz is one of the dietary supplements that has gained much popularity over the years in the market with the unique claim of being a former prescription-only weight loss pill that is now available without any prescription.

Looking at supplements, the company that created it refused to disclose lots of vital information about their company. The information given about the pill is inadequate, which does not make much sense.

Appetite suppressants work by curbing the urge for food and enable the body to burn excess carbs and fats while enhancing weight loss. It contains ingredients that reduce the urge for food. It also increases the metabolism, which increases the potential for fat burning. PhenTabz is a not so strong appetite suppressant compare to prescription diet pills.

The manufacturers claim the pill has two benefits in one. It suppresses the appetite so you will not have an urge for food and it also mobilizes fat while raising the metabolic rate. This may sound great, but the mobilization of fat cells does not have anything to do with weight loss as this fat is likely to just move into other cells in the body.

PhenTabz Manufacturers

PhenTabz was developed by Lexium International but introduced onto the market by Gentech Pharmaceuticals in 2001. Lexium international has been operating for over twenty-five years.


  • PhenTabz promises to boost energy levels and customer reviews seem to support this claim..
  • The over-the-counter version of PhenTabz works in two ways to shed excess weight; it curbs hunger and raises the body’s metabolism.
  • It is not unique, several other appetite suppressants claim to work in a similar manner.

PhenTabz Dosage

PhenTabz is taken twice a day, once before breakfast and once before lunch. It is preferable to take it with water instead of juice or coffee.


  • The major concern with this supplement is the fact that there is no adequate information on its ingredients, which has made many people that are willing to try it out reluctant to make a purchase.
  • Some of its ingredients that have been listed are known to have been banned in many countries, like DMAA.

PhenTabz Ingredients

There are four disclosed ingredients associated with PhenTabz:


This includes caffeine and it is always amongst weight loss supplement ingredients because it is a good energy and metabolism booster. It can also aid in suppressing the appetite. Caffeine is typically used as a supporting ingredient because it enhances the effects of the other ingredients.


This is also known as Methylhexanamine and its included to help act as an additional appetite suppressant. It has been claimed that it is useful for suppressing the appetite for three to four hours. This is good in the sense that it will reduce the consumption of snacks that poses a hindrance to dieting programs. It has not been determined how DMAA may affect health in general. It was banned in many countries when it was linked to several deaths. It can cause high blood pressure, strokes, brain bleeding, and psychotic disorders.


The main active ingredient of Phentabz is found in a proprietary blend the manufacturer termed Ampheta-HCL. Ampheta-HCL is a proprietary list of ingredients that made this product seem to be very stable and act as an effective weight loss pill.


Octopamine has some known to aid in the release and mobilization of fat from fat cells. This fat that is released is usually absorbed by other fat cells immediately so you do not actually lose any weight, you just move the fat around. There is no clinical evidence as to how it can assist with weight loss, and combining it with stimulants like caffeine, it can have a significant effect on the blood pressure rate.


  • Due to some of its known ingredients that are good appetite suppressants, this can help to reduce food intake.
  • Phentabz are good metabolism boosters, which will provide you with additional energy to use in day to day activities.
  • PhenTabz does not require any change in its user’s lifestyle in order for it to work effectively for weight reduction.


  • One negative side effect that has been associated with the use of PhenTabz is sleeplessness.
  • Another side effect is dry mouth.
  • It is advisable to take the pill early in the morning and early afternoon to avoid sleeplessness.

Customer Reviews

This product really cleared up my thinking the first few times I used it, but after a few days this effect wore off and I did not see any other benefits from this product.

I really just wanted a diet pill that would help reduce my appetite, but this product did not help me at all. At first it made me feel a little more alert after I took it, but eventually that went away.

There is no useful information on the bottle to explain what this supplement contains. It also does not say how or where it was made.

This pill has not helped me cut back on my food intake. It made me very jittery the first two days that I took it. I felt excited. Now I don’t notice any effect from it at all.

2 Stars Reviews PhenTabz - Phentermine Alternative
2 stars - "I went to the site and tried to locate information about this drug. All I could find were marketing materials. It promised to not just make me feel less hungry, but it was supposed to help me burn fat too. This is not what happened. I did not notice any results after taking PhenTabz for a month."

Verdict – Rejected

This product cannot be recommended as a safe diet pill. There is very little information about the company that manufactured the product. The entire ingredient list has not been disclosed for this product. There are serious questions about the safety of some of the ingredients. Some of the ingredients in this product have been banned in some countries because they have been known to cause death. For all these reasons we reject this as a healthy weight loss alternative. Non-stimulant Conjugated Linoleic Acid supplement by Feel Spirit will give you better weight loss results.
