PhenTabz Review And Buyer’s Guide (2023 UPDATE)

PhenTabz is a well-known over-the-counter alternative to Phentermine and Adipex. Here’s why you may want to skip this fat burner and try something else.

PhenTabz reviews, ratings, and buyer's guide

PhenTabz once claimed to be the world’s strongest diet pill available without a prescription.

That was back when it was still being manufactured under the name Gentech Pharmaceuticals.

Now manufactured by Lexium International, PhenTabz is still heavily marketed in the US as one of the top diet pills on the market.

With reported claims of losing 2-3 lbs per week without side effects, is it too good to be true?

In this review, we’ll see if it really lives up to the marketing hype. We’ll also take a look at how it compares to other similar supplements on the market.

What Is PhenTabz?

PhenTabz is an over-the-counter alternative to prescription diet pills like Phentermine and Adipex-P.

It was previously manufactured under the Gentech Pharmaceuticals name, which produced non-prescription Pharmaceuticals and had offices in the US and UK.

They manufactured a number of high-end weight loss and mental performance supplements including PhenTabz Teen, ADDTabz and PhenTabz RX.

GenTech soon found itself in trouble with the FTC for making unsubstantiated claims about products while also landing an F rating with the BBB. [1],[2]

PhenTabz Teen and PhenTabz RX soon vanished from their website and the company name changed to Lexium International.

PhenTabz is still available as well as ADDTabz and a sleep aid called REMTabz.

How Does PhenTabz Work?

The manufacturer claims that it can increase the body’s ability to mobilize fat while increasing metabolic rate.

This promotes and enhances fat burning and increases the availability of energy. It is also supposed to help reduce your appetite and help to keep your cravings under control.

All of this together can have a synergistic effect of keeping you motivated.

According to the website, PhenTabz is designed to:

  • Suppress your appetite
  • Increase your metabolism
  • Increase your energy levels
  • Accelerate fat mobilization
  • Lose actual fat and not just water weight

PhenTabz Ingredients

PhenTabz contains a proprietary blend of fat loss ingredients designed to help you lose weight by suppressing your appetite and boosting your metabolism.

Each tablet contains 280mg of:

  • Caffeine Anhydrous
  • Synephrine HCL
  • Octopamine HCL

Here is what each ingredient does and how they work together to help you lose weight faster.

PhenTabz Ingredients

Caffeine Anhydrous

The main active ingredient is Caffeine Anhydrous. Caffeine is a stimulant that has been shown to boost energy levels and metabolism while also suppressing appetite.

Synephrine HCL

Synephrine HCL is another stimulant that has thermogenic properties. This means it helps your body to burn more calories by generating heat.

Synephrine HCL is similar to Ephedrine, which was once a popular ingredient in weight-loss supplements. However, Ephedrine has been banned by the FDA because it can cause serious side effects like heart attacks and strokes.

Octopamine HCL

Octopamine HCL is best known as an effective alternative to Ephedrine and has been shown to boost energy levels and stimulate metabolism. Octopamine HCL is also similar to Phenylethylamine, which is a popular ingredient in many popular weight-loss supplements.

Possible Side Effects

The most common side effects according to customer reviews are dry mouth or sleeplessness, which are to be expected with a stimulant that also acts as a diuretic.

Other side effects may include symptoms such as an increase in blood pressure and heart palpitations.

Less common side effects that users may experience are headaches, nausea, increased heart rate, and difficulty sleeping. These side effects are generally mild and go away after a few days of taking the supplement.

Warnings And Precautions

PhenTabz is not suitable for women who are pregnant or breastfeeding. It is also not suitable for people with heart conditions, high blood pressure, or other medical conditions. If you have any concerns about whether it is right for you, please consult your doctor before taking the supplement.

Pros

Any pros about this supplement would have to be based on the reviews from the official website, which are outdated. No ingredients are listed so an assessment based on ingredients is not available either.

So with that said, it’s pretty hard to list any evidence-based positives about this product.

Cons

  • No ingredients listed
  • Lack of clinical evidence
  • Lack of detailed information on the website
  • Reviews are all from 2016 and earlier
  • The company has an F rating with the BBB

Where To Buy PhenTabz

You can buy PhenTabz from the official website or from the Lexium International website.

The price hasn’t changed in years and is currently being advertised at $69 for 1 month to $249 for 4 months’ supply.

Final Thoughts And Recommendation

PhenTabz is marketed as being as powerful as some prescriptions while being completely safe.

Considering the main ingredients are a proprietary blend, you don’t really know how much caffeine is in each tablet. Therefore you won’t know if it can be dangerous or not.

Plus, there aren’t any recent customer reviews online so again, you don’t know how the current formula performs or if it is safe.

To know how effective PhenTabz is, a full ingredient listing should be disclosed otherwise you have no idea what you are buying.

The manufacturer should also have current customer reviews so people aren’t relying on feedback based on previous formulations.

The Bottom Line:

The bottom line: PhenTabz is not a cheap supplement, even considering the discounted 4-month package.

So you are taking a big risk buying a product that you don’t even know what the ingredients are.

For this price, it would be expected to see a lot more detailed information about the product on the website.

It’s time to consider something better.
