Phentarmine Review - Does This Weight-Loss Supplement Really Work? Are lack of clinical research and side effects deal breakers?

Editor's Review: 3.5 / 5.0

phentarmine-product-image97% of dieters just want a product that works. Yeah, we don’t get the other 3% either. We did one of our in-depth reviews on Phentarmine, examining the ingredients, side effects, customer care and scientific studies. Moreover, we sorted through hundreds of dieter comments posted online. Lastly, we compacted the data we found to give you the information you need.

EDITOR'S TIP: Substitute Phentarmine with a proven fat burner such as Leptigen for better results.

What You Need To Know

To begin, Phentarmine was originally available online for $89.95 per bottle. This diet pill contains hoodia gordonii, ginseng, green tea extract, guarana extract, cayenne pepper, gymnema sylvestre, citrus aurantium and garcinia cambogia. The purpose of this supplement is to help increase weight-loss results. It’s taken daily, 1-2 capsules before breakfast and again before lunch. However, Phentarmine should never be taken after 4pm, due to the stimulant content.

Phentarmine was originally released around 2009 by GS Labs and it was intended as an alternative to Phentermine (a prescription diet drug). This supplement was sold with a 100% satisfaction guarantee (but it is no longer available), but read on…

No Real Clinical Research – “An Issue?”

First off, there is an issue with Phentarmine ingredients. According to our Research Editor, “While Phentarmine was obviously marketed as a non-prescription alternative to Phentermine, there is no documented science to support the weight-loss claims.”

“It didn’t curb my appetite at all and just made me very sick!!!! It says 100% money back guarantee but you can only send it back if it’s unopened!!! RIP OFF don’t waste your money,” said one user.

Another complained, “This stuff doesn’t work for nothing. I’ve taken many different supplements on the market over the last 20 years and I say DON’T WASTE YOUR GOOD MONEY ON THIS STUFF!!!”

Side Effects – “Another Concern”

Phentarmine contains key ingredients such as hoodia and garcinia cambogia, which are not proven to yield weight-loss results. In fact, one user stated, “Its a shame that the Food and Drug Administration have not taken action to remove these fake pills off the market since they are causing people to get sick. DON’T WASTE YOUR $$$$$.

Another said, “Ordered from GS Labs, I took the first pill and it made me very sick.”

The research we’ve conducted has shown if there is one facet of a fat-loss pill or program that is seriously problematic (fad diet ingredients, no clinical studies, bad taste) the chances of weight-loss success for the long term are minimal. In other words, if the formula in Phentarmine do fail to help a lot of people see real results, this could be a major dilemma.

The Science – “Clinical Support?”

Unfortunately there is no real scientific evidence that Phentarmine pills work for weight-loss at all. It appears that GS Labs tried to ride on the success of the diet drug Phentermine. When you look closely at the formula you will find some beneficial ingredients, like green tea and caffeine. These are available in hundreds of other products, so they’re not a claim to fame for this one. We at DietSpotlight need to see documented clinical studies that show it works to help you lose more.

The Bottom Line – Does Phentarmine Work?

Let’s go over the deep look at took at this one. While Phentarmine contains an interesting blend of ingredients, we have doubts about this supplement for long-term weight-loss. After all, this pill isn’t supported by any scientific research and it has actually been pulled from the market. Also, there are numerous customer complaints that Phentarmine doesn’t work as claimed. Not to mention this diet formula was expensive!

Dieters that need to drop pounds at a faster rate, we suggest trying out a weight-loss formula that contains proven fat-loss ingredients and sells for a reasonable price that won’t leave you broke.

Among the best products we’ve seen in 2015 is one called Leptigen. Its proprietary blend of four ingredients has been proven in published scientific studies to help encourage fat loss and elevate metabolism. Furthermore, we can’t pinpoint any discussion of harmful side effects and user feedback posted on the web reveals dieters are seeing great results.

Also, the producers of Leptigen are so very confident in the supplement that they’re offering a Special Trial Offer, nice touch.

Welcome to a vast and plentiful market of diet pills and potential weight loss solutions. In this day and age, you can pretty much find what you are looking for without a doctor’s prescription. Especially since so many weight loss supplements are offered online. Regardless of your body-changing goals, there is likely a product out there for you. Let us take a closer peek at the supplement Phentarmine. It is manufactured by GS Labs, and is claimed to help dieters lose weight more efficiently than mere diet and exercise alone. As you can see, there are a number of key ingredients offered in Phentarmine. More specifically, these are Hoodia Gordonii Extract (a cactus plant extract that suppresses hunger), Guarana Extract (a form of caffeine, which may boost energy levels), Green Tea Extract (may heighten the user’s metabolism), Citrus Aurantium (increases core heat), Garcinia Cambogia (promotes fat burning and curbs hunger), Cayenne Pepper Extract, Ginseng (improves mental acuity), and Gymnema Sylvestre (helps regulate blood sugar levels).

List of Ingredients

Hoodia Gordonii Extract, Guarana Extract, Green Tea Extract, Citrus Aurantium, Garcinia Cambogia, Cayenne Pepper Extract, Ginseng, and Gymnema Sylvestre.

Product Features

Phentarmine is a weight loss pill that is no longer available for purchase. For some reason or another, it was pulled from the diet supplement market. It sold for $89.95 (30-day supply), and was suitable for both women and men, 18 and older. Phentarmine incorporated a slew of active ingredients in order to combat excess body fat. This formula aims to suppress hunger, burn off fat, boost metabolic rates, and heighten energy levels. It does not look like it was offered with a 100 percent satisfaction guarantee. As far as a healthy diet plan and regular exercise are concerned, there is nothing mentioned for Phentarmine.

  • Both men and women could use Phentarmine to potentially assist with weight reduction.
  • This product contains Hoodia Gordonii, which may help suppress hunger.
  • Phentarmine was sold in a convenient pill form.


  • There is no longer an official website provided for Phentarmine.

  • Phentarmine no longer appears to be available for purchase.
  • Some users have had negative side effects occur when taking this diet pill.
  • There is little information on the company that makes Phentarmine.


All in all, Phentarmine is not a product we would recommend. It comes across like an Ephedra-based weight loss supplement. Even if this formula does not contain Ephedra, it apparently contains other ingredients that can cause negative reactions. Furthermore, Phentarmine is no longer sold online through an official website. Even when it was offered, the cost was rather high at $89.95 per bottle.
