PhenRx was created by NexGen BioLabs as an over the counter alternative to the prescription strength weight loss medication Phentermine. This report was written on it to evaluate what it is supposed to do as a weight loss supplement and how effective it really is. Read on to find out if this diet aid that is available without a prescription is worth the money. We’ll look at the company’s claims, the ingredients in their proprietary formula Fenphentamine HCL, what other people’s experiences have been, and where to buy it for the lowest price.

About PhenRx

Taking PhenRx is as simple as taking a pill a half hour before breakfast and then another a half hour before dinner. NexGen claims that PhenRx is clinically proven to help lose weight by:

  • Suppressing your appetite – This most likely comes from stimulants in the pills
  • Increasing your metabolism – They claim the product stimulates the thyroid, which influences metabolism
  • Enhancing your metabolic function and fat burning – I’m not sure what they mean here, I assume they mean they will increase your metabolic rate, which means you will use more energy when you are at rest, burning fat

They also say you should feel an increase in energy and mental focus. This is also due to the fact that there are stimulants in it, but it can be effective for increasing your motivation to workout, which is important to do when you are trying to lose weight fast.

NexGen also sells a weight loss product called PhenRx PM that can be used at night to complement PhenRx. It is a “thermogenic non-stimulant nighttime fat burner”.

Fenphentamine HCL Ingredients

Unlike some other weight loss medication alternatives, PhenRx actually list the ingredients of Fenphentamine HCL, the proprietary formula in the weight loss pills. It’s a huge plus for the product and creates more trust in the company by being able to know what they are actually giving you. That said, the amounts of each ingredient and how they mix them isn’t provided. Please do not try to blend these ingredients yourself to try to make your own. NexGen has put a lot of time into researching and developing the PhenRx ingredients and formula. Here’s their list:

1,3,7 – Trimethylxanthine (Caffeine)

Yep, that fancy name there is just the chemical name of caffeine. Used to suppress appetite and give you energy. Make sure you are careful about drinking coffee after taking a pill; you may feel completely wired after double dosing on caffeine.

Beta-Phenylethylamine (PEA)

This is a stimulant that is supposed to help increase your mood by both increaseing dopamine production and slowing down its absorbtion by dopamine receptors. This increase in mood works to help suppress appetite. There has also been studies thowing that it may help to increase metabolism and burn fat more efficiently.

Synephrine HCL

This is a common dietary supplement for promoting weight loss. It’s often used in conjunction with caffeine as it has been shown to be more effective this way. The HCL salt is a synthetic version of the synephrine that occurs naturally in oranges, with the bitter orange having the highest concentration.

N,N-dimethyl-4-hydroxyphenylethylamine (Hordenine)

This is a naturally occuring alkaloid that works as a stimulant. It is used in weight loss supplements as a thermogenic to increase metabolic rate and fat burning.

Schizandrol A

This is used to improve memory and focus. It’s found in a lot of brain supplements because it has been shown to improve cognitive functions as well as reduce stress.

Yohimbine HCL

A mild MAOI inhibitor, it has stimulant effects and has been studied for its weight loss properties. The weight loss may come from its ability to block receptors that inhibit fat loss, but more research needs to be done. Its effectiveness on its own isn’t very much but it is often used in combination with other ingredients to form supplements.

While these are the effects of each ingredient in the Fenphentamine HCL formula created for PhenRx, it is impossible to say what their effects really are when used in combination with each other or at the dosage they are used at. This section is just meant to give you an idea of what you are putting in your body.

Side Effects

While the side effects PhenRx has, listed by NexGen, are minimal, it is always recommended to check with your doctor before taking any sort of weight loss pill or starting a new diet. This product does contain some stimulants that can increase heart rate and blood pressure when you take them, so be careful. What NexGen does say about their product is that is isn’t meant for women that are pregnant or nursing, or anybody with a known medical condition like diabetes, high blood pressure, heart disease, or cardiovascular disorder. They also warn against combining with other stimulants. On the NexGen website, the only side effects listed are dry mouth and sleeplessness, which could be said of basically any stimulant. I’m going to make an assumption here and say that these can’t be the only side effects that one might experience, there possibly just hasn’t been enough studies done on the product.

Does PhenRx Work?

PhenRx does work. While it may be difficult to find studies done on the effectiveness of Fenphentamine HCL, there has been lots of research done on many of the ingredients it contains that have shown to assist with weight loss. From reviews I’ve read, people are seeing results in the first week they use it. Usually around 2 pounds, some as high as 5 pounds a week. To me, 5 pounds a week seems a bit high, but it’s difficult to say without knowing their starting weight.

PhenRx Customer Reviews

We have yet to receive any PhenRx reviews so we don’t have a whole lot to say about it. Until we receive our own customer reviews, there are many other websites out there that have tons of them, such as this one. If you buy PhenRx online or in store, please give us your feedback from it. Sharing your results with our community will help others make a more informed decision.

PhenRx vs. Phentermine

PhenRx was designed to be an over the counter Phentermine alternative. Phentermine is a psychostimulant drug in the phenethylamine class, making it very similar to amphetamine. This is why is requires a prescription and cannot be used for long periods of time. There isn’t anything to suggest that PhenRx could be habit forming and there are no warnings for taking it over long periods of time. Their efficacy seems to be similar, although Phentermine is much more tested and researched. The list of side effects for Phentermine is much longer, although again this could be due to the rigorous testing through clinical trials. The over the counter PhenRx is marketed as a health supplement and while their ingredients are FDA approved, their claims have not been evaluated by the FDA.

PhenRx versus Phentemine 375

Phentemine 375, or Phen375, is another over the counter Phentermine substitute. It has been around for a while and is possibly the most popular of the weight loss supplements available without a prescription. However, that doesn’t mean it’s more effective than PhenRx. Both have had their fair share of bad reviews. Their ingredients are very different so I suggest looking at both and making an educated decision on which one may better suit your needs.

PhenRx vs. Phentramin-D

Phentramin-D is made by Lazarus Labs and sold as a weight loss supplement, just like this product. The price on both of these are pretty similar and the ingredients have some overlap, but Lazarus gives a 30 day money back guarantee on their product. You don’t find those too often! Read a review here on Phentramin-D and see if it is right for you. They also have an exclusive coupon code for it at TopOTCAlternatives which makes it priced slightly better.

PhenRx PM

This nighttime formula weight loss pill can be used in conjunction with the regular PhenRx supplement. It is designed to suppress appetite, increase metabolism, and increase metabolic rate. Basically the same stuff as PhenRx, but instead of supplying energy, it’s supposed to enhance R.E.M. sleep. All you need to do is take one capsule a half hour before bed. The ingredients of PhenRx PM include Green Tea Extract (50% EGCG), Magnolia Bark Extract, Phosphatidylserine, Coleus Forskohli, Raspberry Ketones, L-Theanine, 7-KetoDhea, Gamma-aminobutyric Acid, Melatonin, and Black Pepper Extract. I was surprised to read that there is absolutely no overlap between the daytime and nighttime supplements. This formula is more natural with lots of herbal extracts. I’m sure the reason they aren’t found in the daytime formula is that stimulants are just simply more effective at assisting with weight loss.

Where To Buy Online

PhenRx

After searching for where to buy PhenRx online, the best bet seems to be directly from the NexGen website. There are a couple 3rd party resellers that carry it on Amazon, but at the time this is being written, the two reasonably priced options are not in stock and the third is a ridiculously priced $120 per bottle, over double what NexGen is selling it for. It’s also difficult to say how quickly these third party sellers might be moving the product. If it sits for too long, the ingredients may not be as powerful. Also, if you have any issues with the product, it’s better to deal with the manufacturer than a third party seller. That said, Amazon does a pretty good job at mediating any issues. Aside from Amazon, there doesn’t seem to be anywhere to purchase online.

PhenRx PM

The nighttime version is also available directly from NexGen. It’s slightly cheaper than the daytime one and only needs to be taken once per day instead of twice. I wasn’t able to find PhenRx PM on Amazon or anywhere else online like I could for PhenRx

Where to Buy in Stores: CVS, GNC…

PhenRx

Our team went out and looks for PhenRx in CVS, GNC, Walgreens, Walmart, and Rite-Aid. We weren’t able to find it in any of these stores. This seems to be pretty common among these strong over the counter Phentermine alternatives like Fenphentamine. Maybe when they gain more popularity as a whole they will become more readily available.

PhenRx PM

We also tried to find PhenRx PM in CVS, GNC, Walgreens, Walmart, and Rite-Aid. This search also didn’t result in us finding anything. PhenRx PM actually does seem to be more likely to appear on shelves in-store just due to the ingredients it contains. Hopefully we’ll see both show up soon.

PhenRx Best Price

PhenRx

Due to it being difficult to find anywhere other than the manufacturer’s website, the NexGen website is the best price on PhenRx. Check back as we will try to update this when Fenphentamine becomes available in other stores. If we find any coupons for these products we will add them into this section.

PhenRx PM

Same as the other version, the best price on PhenRx PM is on NexGen’s website. This is simply due to it not being available anywhere else at this time.
