According to WebMD, almost half of us are trying to lose weight at any given time. And many of us have tried before. So it follows that some of us could use some help. The modern world isn’t set up for weight loss, and even our genetics can work against us.

If you’ve worked hard to lose weight you’ve also probably looked into supplements and done your research. And you’ve probably come across the prescription drug Phentermine. We did some research ourselves into Phentermine, including where you can buy it online. We also came across some great legal alternatives to Phentermine, including PhenQ, PhenGold, and Phen24.

Prescription Phentermine

Right away we should note that Phentermine is a controlled, prescribed medication. It is listed as an amphetamine replacement. It is generally regarded as a prescription reserved for the medically obese, and is only designed to be used in short-term applications. Given that tight legal parameter, you can only obtain it on a doctor’s orders. If an online source claims you can get it without consulting a doctor, beware: it could be a scam or even illegal.

Unlike PhenQ and PhenGold, Phentermine is available from a multitude of sources, and not all of them are safe or legitimate. One of the reasons we liked the alternatives, such as Phen24, is that they are sold directly by the manufacturer, so you can be sure of the safety and legality of the product.

Prescription Phentermine is a drug, like we mentioned, and it can have serious side effects. These include diarrhea, trouble sleeping, dizziness, and even an increase in blood pressure. Not to mention all of the interactions with other medications. Phentermine was pulled off the over-the-counter market in part because of deadly combinations with other drugs.

Phen24, PhenGold, and PhenQ are not prescriptions, and therefore have no dangerous side effects, and they don’t interact dangerously with other medications.

How Phentermine Works

The prescription weight loss drug is used mostly by people who have been diagnosed with severe obesity. A doctor looks at the serious health effects caused by a patient’s weight, and gives them a short-term prescription for phentermine. 

The way it works is by suppressing appetite. In people on the higher end of obesity, their bodies can get by with a lot less calories, forcing their biochemistry to burn off the large fat stores. If you are not so overweight that you are suffering health effects, you may not be able to afford to suppress your appetite this way.

Unlike supplements like Phen24, phentermine blocks the hunger signals in your brain. If you are only a few pounds over your target weight, suppressing your hunger signals this way could deprive you of vital nutrients throughout your day. Carrying 5 pounds of extra weight means you don’t have the fat stores to safely block your instinct to eat.

Even with the most severe cases of obesity, doctors do not prescribe phentermine for longer than a few months. The alternatives we found, on the other hand, such as PhenGold and PhenQ, can be taken everyday for months on end, with no safety concerns.

How the Alternatives Work

Prescription medicines need a doctor referral because of the way they interact with your biological functions and your brain chemistry. The alternatives we looked at use natural ingredients working in concert to help your body arrive at a healthy appetite level, burn fat and sugars, and even make you feel better.

PhenQ: Best Unique Ingredient

Is There a Return Policy? Yes, all three products feature lengthy money back guarantees. One of the very best weight loss supplements on the market just happens to be a great phentermine replacement. It’s called PhenQ, and it relies on a unique, proprietary ingredient called α-Lacys Reset®.

Lacys Reset is a combination of two natural compounds, alpha-lipoic acid and cysteine. Both of these are found in the human body, already, and they help your body by attacking free radicals. Alpha-Lipoic Acid, by itself, helps your body break down glucose (sugar), and cysteine by itself helps you metabolise proteins.

Combined together in a bonded compound, α-Lacys Reset® helps your body increase oxygen to working muscles, burn sugar, and build better muscle. In fact, research presented by PhenQ shows that not only do people with α-Lacys Reset® lose body fat, they also build more lean muscle.

Unlike simple appetite suppression, this means PhenQ helps you lose fat, not just weight, and add lean muscle for longer term and sustainable weight management. 

While the Lacys Reset is a great ingredient, PhenQ also includes some other researched ingredients to help with total weight and fat loss. They have caffeine extract for added energy, nopal cactus fiber to help you feel more full when you eat, and a proprietary blend of thermogenics to boost your metabolism.

One of the best things about PhenQ versus phentermine is that you can take it as long as you want. You don’t need to stop taking it after a certain amount of time. And because you don’t need a prescription, you can stop taking it and restart whenever you like, according to your weight loss goals.


  • No prescription needed.
  • Legal and safe.
  • Unique ingredient, α-Lacys Reset®.
  • Statistics to back the claims.
  • 60 day money back guarantee.


  • Only available from the website.
  • Best results after two months.

Phentermine is a prescription that can have dangerous side effects, and it only suppresses appetite. PhenQ, on the other hand, can help you actually lose fat and put on lean muscle. You can get a two month supply, plus a free third month, for $139.90 on their website.

PhenGold: Best for Trusted Formula

Perhaps you’re a little new to diet supplements and you don’t want to take too many chances. That’s totally understandable, and that’s one of the reasons we don’t recommend trying to find phentermine online. If that’s the case, we recommend PhenGold because it has one of the best-researched ingredient lists.

There are a number of supplements for weight loss on the market, and there are a ton of common ingredients. One of the reasons we see so many common ingredients is that they work. A lot of research has been done on these natural compounds, and PhenGold has put the best and most studied of them in their product.

PhenGold has a balanced formula that looks at three main aspects of diet and exercise supplementation: energy, thermogenics, and mood.

Energy is hugely important when it comes to a new workout regimen. After all, if we’re trying to lose weight it might be because we haven’t been exercising as much as we should. PhenGold uses Green Tea, Green Coffee, and Caffeine to help boost your energy. Not only that, but the antioxidants and unique catechins in Green Tea and Coffee have been studied to help you burn fat in their own right.

Next, PhenGold has researched ingredients that fall into the category thermogenics. Like the name sounds, thermogenics can help your metabolism literally heat up and burn more calories, more efficiently. For this, they use a Vitamin B Complex, Cayenne Pepper, and Rhodiola Rosea, all studied to help you burn fat and sugar.

Lastly, we should talk about mood. Let’s face it, when we feel a little down we sometimes reach for something sugary to help lift us up. And we can feel more than a little down after starting a diet and exercise routine. By including three ingredients that help mood and focus, Phen Gold helps us to feel better throughout our routine, helping ensure we stick with it over a longer time span. The ingredients here are the amino acids L-Tyrosine, L-Theanine, and DMAE.


  • Well-researched ingredients.
  • Helps with mood.
  • Increased metabolism.
  • Safe and legal.
  • 100 day money back guarantee.


  • Does not include fiber for appetite.
  • Most affordable with larger orders.

There’s no replacement for researched ingredients and studied formulas. If you’re looking for something with a lot of paperwork to back it up, look no further for a phentermine replacement than PhenGold. You can get three months for the price of two, or $119.99, on their website.

Phen24: Best All-Day Formula

Our bodies work differently at night than in the day. There’s the obvious fact that we sleep at night (generally). But our total body chemistry changes, as well. For instance, during the day our metabolism is working to keep us up and moving about, while at night we have more time to eat even though we’re slowing down. The makers of Phen24 have taken all that into account and made a truly 24 hour formula for weight loss.

The key to the Phen24 formula is that they’ve really designed two supplements to be taken on the same day. They realized that taking a pill in the morning for benefits you need to see at night doesn’t really make any sense. So they’ve split their formula up into two different pills, one you take in the morning, and one you take just before bed.

During the day, our bodies can use help with metabolism, mood, and energy. So the Phen24 daytime supplement has guarana extract and cayenne pepper for thermogenics, caffeine for a jolt of energy, and L-Phenylalanine for mood. They also have three essential minerals that help our metabolism stay balanced: zing, manganese, and copper.

At night, Phen24 realizes that one of our biggest enemies is the late night snack. Lots of people have taken to intermittent fasting, or not eating after a certain time of night. Part of the reason this works for weight loss is that we’re so inactive after sundown. We typically come home, or engage in relaxation. But some of us also take this extra downtime to eat. Phen24’s night time formula includes Glucomannan, a proven fiber supplement from the konjac root that can help us feel more full. By taking glucomannan before bed, we can feel more full going into our sleep cycle.

While the day and night supplements work fine alone, it’s really in tandem that they reach their potential. The daytime formula increases our metabolism, and the L-Phenylalanine converts in our body ultimately into dopamine, helping us feel better in body and mind. Then the night formula with its glucomannan aids in more effective rest by keeping us asleep instead of snacking. And when we go back to the daytime formula, being better rested, we have yet more energy and our mood is even more improved.

This all results in eating less, exercising more, and a boosted mood thanks to the full cycle of the supplement’s ingredients.


  • Truly 24 formula. 1
  • Formulated by a certified Herbalist, Nutritionist, and Naturopath.
  • 60 day money back guarantee.
  • Reduces stress, improves mood.
  • Helps curb appetite.


  • Requires taking on a schedule.
  • Should not take while pregnant or nursing.

By working with our body’s chemistry, rather than restricting it like prescription phentermine, Phen24 helps us with our mood, our sleep, our appetite, and in the end with our weight loss goals. A two month order, with a free third month, is $149.99 on their website.


We should all be careful about ‘wonder drugs’ that promise the world. Phentermine is a prescription medication that does help people lose weight. But it does so by altering the very chemistry in our brains. And it’s only available from a doctor, and they will only prescribe it for small amounts of time. On the other hand, we’ve identified three safe, legal, and well-researched alternatives that work with our body to help us reach our goals. 

We don’t recommend trying to find phentermine on the internet, given that you need a doctor’s prescription, and finding prescriptions online can lead to unsafe products, and possibly legal consequences. However, we do recommend either of the other products we found, PhenQ, PhenGold, or Phen24.


Is Phentermine Legal?

Only with a prescription. We caution anyone who finds it online that it may not be a safe outlet for purchasing prescription drugs.

What Are The Side Effects Of Phentermine?

Dizziness, dry-mouth, diarrhea, and high blood pressure. Also, because it is a prescription, only your doctor can know if it will have any other possible risks to you given your health or other medications.

Do PhenQ, PhenGold, or Phen24 Have Side Effects?

No. One of the reasons we recommend all three of them is that they are safe and made from all natural ingredients.

Do I Need a Prescription For Them?

No. You can order them directly from their manufacturers on their websites.
