PhenTabz Review – Everything You Need to Know


PhenTabz is a multi function weight management product by GenTech, claiming to offer a number of weight loss related benefits for users. Gentech describes Phentabz as a “miracle pill” for weight loss, which is a bold claim. We’ve looked into Phentabz carefully in order to find out whether it lives up to these claims or not, and below you’ll find our Phentabz review, exploring everything we’ve uncovered about this product.

What is Phen tabz?

There are three different Phentabz products available on the market in 2020: Phentabz, Phentabz Teen (aimed at 16 to 19 year olds), and Phentabz Plus (only available with a prescription). All of these are variants on the same formula, and offer similar benefits. Phentabz is a weight loss supplement that claims to speed up your metabolism, driving excess fat out of your body. GenTech claim that Phentabz is aimed at helping people who want to lose weight but have had no luck with exercise.

Phentabz is also claimed to suppress appetite, reducing hunger pangs and helping with weight loss in a number of different ways. Phentabz diet pills are recommended in a dosage of one capsule per day, and are easier to take than many other weight loss supplements, which require preparation before you can take them.

Phentabz ingredients

The Phentabz website does not list its ingredients, which should raise red flags instantly for consumers. As far as anyone can tell, Phentabz contains three main ingredients: caffeine, octopamine, and methylhexamine, otherwise known as DMAA.

Caffeine is a simple stimulant found in many different products. It’s not going to make a huge difference to anything in either positive or negative ways. The other two, however, are more interesting chemicals with effects on your metabolism.

Octopamine is a chemical that’s generally thought to have minor fat burning effects. There’s no research to support this claim yet, but it doesn’t seem to be a particularly powerful ingredient.

The major ingredient that’s worth looking into is DMAA. This is the main ingredient of Phentabz, and it is illegal in many countries and banned by most major sporting organizations. It is considered a potent supplement, and one that may well be dangerous to consume. The fact that the Pnetabz website does not list this is a major cause for concern!

Does PhenTabz work?

Phentabz doesn’t have much scientific research available to back up its claims. There’s no clear link between using this product and weight loss, and while there are customer reviews available on their website, all of them seem to have been paid for by the company. If you see positive phentabz customer reviews, then, they certainly can’t be trusted. The bottom line is that Phentabz might work to some minor extent, but it’s certainly not the miracle product that the company claims it is. It’s also genuinely dangerous, thanks to the range of side effects we’re about to discuss.

PhenTabz side effects

The fact that the major active ingredient in phentabz is illegal in many countries should be more than enough to warn you away from this product, and the side effects are minor but likely. Once again, the website for phentabz does not list these side effects, which should be cause for concern.

DMAA and Octopamine have recorded history of causing severe nausea and paranoia, while the other highly possible side effects of this product include heart rate increase, breathing problems, anxiety, irritability, and insomnia.

DMAA in particular is a problem. According to the Food and Drug Administration (FDA), DMAA can have major side effects that can cause all sorts of cardiovascular problems. As well as raising blood pressure significantly, DMAA can cause shortness of breath and a feeling of chest tightness, and can even cause heart attacks in some users.

PhenTabz lawsuits

Derek Vest, the former president of GenTech, was sentenced to 18 months in prison and fined $2.5 million dollars after being found guilty of misleading consumers through mislabelling of supplements sold by Gentech. Most products from Gentech contain DMAA, which is not an FDA approved dietary supplement, and is illegal in many countries.

As early as 2012, the FDA issued warning letters to companies using DMAA, telling them to remove the ingredient from their products. Gentech has continued to sell products containing this hazardous ingredient, and the lawsuits around Phentabz center around their purposeful failure to disclose this ingredient on the label of their products. While they now acknowledge the presence of DMAA, GenTech make no acknowledgement of the dangerous nature of this ingredient.

Phentabz is therefore currently illegal in the USA, thanks to its use of DMAA.

Phentabz vs Phentermine

Phentabz is a specific product that differs in many ways from Phentermine, a common prescription weight loss drug. The two are entirely unrelated, and it seems likely that PhenTabz uses “phen-“ in its name in an attempt to suggest to consumers that it is similar to Phentermine, a far safer and more legitimate weight loss product. Phentermine is a safe prescription weight loss supplement, while PhenTabz is a dangerous weight loss product with a wide range of possible side effects and no connection at all to Phentermine. If you’re uncertain as to which of these two products is better, we’ve got a clear answer for you: It’s Phentermine. There’s no uncertainty about this. Phentermine is a legitimate and safe weight loss supplement, and wins out over PhenTabz in every way.

Where can I buy Phentabz?

PhenTabz can currently only be purchased from the GenTech pharmaceuticals website, at a base price of $69.99. It’s also available from some of the larger eCommerce sites such as amazon for a similar price, although sellers on these sites are likely to be untrustworthy.
It is worth remembering, however, that due to the illegal nature of DMAA in many countries including the United States, online ordering of PhenTabz is not a reliable option. Your order may well be seized by customs for containing banned substances, and you will not be able to get your money back in that case! It is entirely legal for a website to sell you a product that it then can’t ship for legal reasons, so watch out! Just because a product claims to be available in your area does not mean that it’s legal.


PhenTabz is difficult to find, expensive, and straightforwardly illegal in many countries thanks to containing a dangerous ingredient with no proven advantages. As such, it is easy to state that PhenTabz is not a product that you should ever consider taking, regardless of the (dubious and paid for) user testimonials on the GenTech website.

There is no clinical research backing up the claims made about PhenTabz’s effects, the ingredients are hazardous and banned in many countries, and GenTech itself has an “F” rating from the Better Business Bureau. Phen Tabz is in no way a good choice, and there are far better and more legitimate products available to help you with weight loss without the legal issues and the risk of heart attacks and death.

The bottom line here is that GenTech is an extremely shady company that appears to be lying about their product’s effectiveness and failing to divulge its ingredients and possible side effects. Not only should you avoid PhenTabz, you should also be extremely wary of all other products offered by GenTech, as this company is not a reputable source of medical supplements in any way at all.
