Phentermine is a notorious diet pill that is only supposed to be available on prescription, and is classified as a controlled substance. So we were surprised to see that it is openly offered for sale to everyone from what looks like a specialist website. Is this even legal? Is it the real thing? We take an in depth look at this supplement, and the website to find out more.

Phentermine was once routinely prescribed for weight loss in the USA and is the supplement with strong speedy effects that many people imagine when you say “diet pill”. These days many diet pills have the word “phen” in their name to convey this impression.

What You Need To Know About Phentermine

Phentermine is a prescription weight loss pill that many people want, despite the risk of very real side effects. This has led to lots of supplements being similarly named in order to confuse and trick people into paying a lot of money for inferior products. The website sells a rip off supplement that they try to pass off as Phentermine but is actually called Phentarmine and is nothing to do with the prescription drug. Avoid it.

What Are The Side Effects Of Phentermine?

Real Phentermine has numerous side effects including cardiovascular effects, such as heart palpitations, high blood pressure, stroke, angina, heart attack, and lasting heart valve damage. It affects the central nervous system causing insomnia, jitteriness, mood swings, dizziness and psychotic episodes. It can cause vomiting, nausea abdominal pain, and other gastro intestinal side effects.

Without knowing the true ingredients of the Phentermine substitute Phentarmine it is impossible to predict potential side effects. This supplement could be dangerous.

How Much Does Phentermine Cost?

The rip off Phentermine product called Phentarmine is very expensive and totally overpriced. After all you are paying for the Phentermine name and not for an unknown unproven supplement as is the real case. The capsules that come in white with a blue speck just like genuine Pricing is as follows:

  • 120 days’ supply costs $271
  • 90 days’ supply costs $187.00
  • 60 days’ supply costs $156.00
  • 30 days’ supply costs $87.00

The blue and white Phentarmine capsules cost;

  • 120 days’ supply costs $196.00
  • 90 days’ supply costs $155.00
  • 60 days’ supply costs $119.00
  • 30 days’ supply costs $65.00

Phen Caps are not as expensive;

  • 1 x bottle of Phen Caps (60 capsules or 1 month’s supply) costs $49.95 with an added $5.00 shipping charge to US addresses
  • 3 x bottles of Phen Caps (3 months supply) costs $129.95 including free shipping
  • 6 x bottles of Phen Caps ( 6 months supply) costs $249.95

Our Verdict On Phentermine

We don’t like real Phentermine anyway, but we are disgusted with the website. This site blatantly attempts to rip customers off by selling a product that looks identical to the real thing, yet is nothing like the original prescription drug. In our book this is nothing more than a fraud.

There is no information about Phentarmine, the copy product. One thing is for sure; it is not the original prescription diet pill, and it will not work in the same way. It is nothing more than an expensive rip off hoping to catch people out who are looking for the real supplement.

Phen Caps is not too bad. It will not work in the way as described and it is nothing at all like Phentermine but at least it does not claim to be it.

We cannot understand how is getting away with this and although it is unsafe to take genuine Phentermine we are disgusted how this website is unabashedly ripping off customers.

Phentermine is illegal. You cannot buy it online like this so if you are searching for this dangerous drug, you are going to be disappointed.

We do not recommend Phentermine, Phen Caps, or Phentarmine – the drug trying to pass itself off as the real thing.

Phentermine Review

Phentermine is classified as a psycho-stimulant drug in the amphetamine class of substances. It comes under numerous brand names depending on the country you are in, including Adipex and Suprenza.

The thing to know about this supplement is that it is strong. Dimethylphenethylamine, to give the active chemical its full name, is a man made drug classified as a type of amphetamine and it works pretty much the same as the illegal drug in that it will decrease your appetite and increase your energy levels. Phentermine will undoubtedly help you lose weight while you are taking it.

However, taking amphetamine type substances is not safe especially when taken long term. It puts a strain upon heart and blood pressure, and has numerous dangerous side effects. It leads to permanent heart valve damage.

Phentermine Facts

  • Genuine Phentermine is not easily available to buy openly over the internet
  • does not sell genuine Phentermine
  • is a scam site pushing the very similarly named Phentarmine in the hope that customers will not notice

Phentermine is still available in most countries under prescription but is only ever prescribed for short periods of time and under strict medical supervision. There is a very long list of conditions that this prescription medication will not be suitable with, including any tendency towards illegal drugs or mental illness. In addition, it will cause a lot of side effects and it is addictive.

How to Take Phentermine

The supplements do not come with any directions about how to take them.

Despite the real risks to health, this supplement is very well known, especially in the USA where it was once freely prescribed. Because it works, people want it and advertisers often give their products names that sound like Phentermine to further this impression.

Phentermine Concerns:

  • is ripping off customers
  • The Phentermine substitute Phentarmine does not come with any ingredients information
  • Could cause potentially dangerous and unpredictable side effects is a USA based website that seems to offer the real thing to customers, but don’t be fooled. It does not sell genuine Phentermine.

First up you are given a choice whether to buy without a prescription or with a prescription.

Choose the no prescription option and you are taken to a product called Phen Caps. This is a legal weight loss supplement billed as an alternative to Phentermine. We covered Phen Caps in a previous review and found that it was a reasonably safe although probably ineffective for weight loss. In our opinion the most dangerous thing about it is the name!

Choose the “buy Phentermine” or “buy Adipex” option, and you are taken to another site called

This site explains how Phentermine works and displays before and after pictures of successful dieters. However, when you get to the buying page, it seems that you are not buying this supplement, but a product called Phentarmine. This will mislead most customers who will not notice this small discrepancy.

What Does Phentermine Claim To Do? claims to sell you the real thing online, but this is nothing more than a scam. The rip off supplement actually on sale is called Phentarmine. It is not the real thing.

More openly you can also buy Phen Caps from the website. This is billed as a Phentermine equivalent supplement.

The Phen Caps advertising claims,

Phen Caps are an alternative to the prescription drug, Phentermine. They give benefits that are similar results to Phentermine, such as suppressing your appetite, stimulating your metabolism and increasing your energy levels. And all of that without the side effects of Phentermine!

There is no evidence that any of this is true.

The so called Phentermine page describes how it works and how effective it is for weight loss. This gives the impression that genuine Phentermine is on sale.

The advertising states,

First approved by the FDA in 1959, Phentermine has helped millions of Americans to achieve real weight loss success! Phentermine suppresses appetite and stops cravings, making it easier to stick to a healthy diet and make better choices.

When you come to buy the drug, only the eagle eyed will notice that you are not actually buying Phentermine but PHENTARMINE. This scam is really that simple.

Does Phentermine Work?

The simple answer is no. The supplements will not work like Phentermine, because they are not actually the real thing.

We covered Phen Caps in a previous review and felt it was totally ineffective. We cannot find any information about Phentarmine such as an ingredients list. It may do something, but it could be dangerous and more likely is totally ineffective.

After all, if Phentarmine really worked for weight loss, the advertisers would not have to go to such lengths in order to sell it.

What Are The Ingredients of Phentermine?

There are two supplements on sale from

  • Phentarmine: We were interested to find out more about Phentarmine and the ingredients. However tracking this supplement down is no easy job and there is conflicting information out there.
    According to one industry source Phentarmine contains natural herbal ingredients such as green tea extract, Hoodia, Guarana and Ginseng. Other sources claim that Phentarmine contains stimulant ingredients including L-Phenylalanine, Synephrine HCL, L-Carnitine, L-Taurine, Theobromine, and 7-keto (DHEA). Bearing in mind that is trying to pass this supplement off as the real thing, rather than an OTC supplement, how can you trust this supplement anyway?
  • Phen Caps: This supplement contains a blend of stimulants including caffeine, synephrine, methsynephrine, PEA and Hawthorne berry extract. Some of these ingredients can have a stimulant effect but the quantities are so low, they are unlikely to cause adverse affects. We covered Phen Caps in a previous review and found it lacking.

Does Phentermine Have Any Side Effects?

Side effects of Phen Caps are likely to be mild and include heartburn, mild headaches, and nausea. However without knowing anything about the ingredients contained in Phentarmine, it is impossible to predict potential effects accurately. These may include:

  • Increased heart rate
  • Increase blood pressure
  • Vomiting
  • Nausea
  • Dizziness
  • Increased risk of heart damage or stroke
  • Headaches

Not suitable for individuals under 18. Avoid if you are pregnant or breast feeding. You should never take supplements without understanding the ingredients and the potential side effects, so you should avoid using this supplement.

Are There Any Customer Reviews For Phentermine?

Despite searching through the internet, we were unable to track down even one genuine review for either of these supplements.

Does Phentermine Offer a Money-Back Guarantee?

The supplements sold via are not covered by a money back guarantee.

Where Can I Buy Phentermine?

Neither of these supplements is sold in the shops or stores. They are both on sale from, a scam website that gives the impression it is selling the real thing, as well as a legal alternative (Phen Caps).
