Thousands of weight watchers and fitness buffs look up for Phentermine Reviews online. It is after all, one of the oldest and most popular weight loss drugs in the world.

In 2007, Phentermine was approved as an adjunct to a low-calorie diet and exercise for the short-term treatment of obesity. However, its long-term efficacy and safety have not been established.

The question is, do you go by all the glossy Phentermine reviews being posted online? Is Phentermine the ideal weight loss drug for a recreational fitness buff looking to lose a few pounds?

In this article, we cut through the clutter and bring to you an unbiased Phentermine review. We also provide three safer and more sustainable alternatives for weight loss.

Top 3 Alternatives to Phentermine

  • PhenGold – Best Natural Alternative to Phentermine
  • Leanbean – Best Alternative to Women
  • PrimeShred – Best Thermogenic Fat Burner

What is Phentermine?

Phentermine is a medication used for the short-term treatment of obesity. It is a sympathomimetic amine, which means it stimulates the sympathetic nervous system.

Phentermine is also a hunger reducing drug that affects the central nervous system. It is similar to amphetamines and has stimulant properties. It is sold under the brand names Adipex-P, Fastin, Ionamin, Obenix, and Suprenza.

Phentermine is approved for the short-term treatment of obesity. The exact mechanism of action is not known. It is thought to decrease appetite by working on neurotransmitters in the brain, such as norepinephrine and dopamine.

When the levels of these neurochemicals are increased, they help to decrease appetite and cravings.

Phentermine is usually prescribed for people who are obese or have a body mass index (BMI) of 30 or more. It is also prescribed for people with a BMI of 27 who have other health conditions, such as diabetes, high blood pressure, or high cholesterol.

This means that the ideal candidate for Phentermine is someone who is obese or overweight with a body mass index (BMI) of 27 or more. That’s classified as obese.

This brings us to the next big question. Can you use Phentermine if you are not obese and looking to get ripped for the upcoming beach season? We will answer this and a lot more.

How does Phentermine work?

Amphetamines are CNS (central nervous system) stimulants that increase alertness, decrease fatigue, and improve focus and concentration. They are also hunger reducing drugs.

Hunger reducing drugs work by stimulating the hypothalamus gland in the brain to release norepinephrine, a neurotransmitter that signals a fight-or-flight response. This increases metabolism and suppresses appetite, leading to weight loss.

Phentermine is a sympathomimetic amine and a hunger curbing drug similar to amphetamines. It works by decreasing the reuptake of norepinephrine and dopamine, two neurotransmitters that are responsible for feelings of hunger.

By reducing the reuptake of these neurotransmitters, Phentermine decreases the hunger and causes weight loss. It is not a magic pill contrary to what it seems.

While it is approved for short-term use as a hunger curbing drug for overweight or obese individuals, it is typically prescribed for people who are struggling to lose body weight through diet and exercise alone.

Here’s what you can expect after taking Phentermine for weight loss.

Increased alertness

When you use a CNS stimulant like Phentermine, you can expect to feel more awake and alert. This is because amphetamines increase the levels of norepinephrine and dopamine in the brain, which are responsible for feelings of alertness.

Phentermine may also improve your ability to focus and concentrate. This can be helpful if you’re trying to lose weight by making healthier food choices and being more active.

Decreased fatigue

Amphetamines like Phentermine are also known to decrease fatigue. This can be helpful if you’re struggling to stay motivated to lose weight. As you reduce your calorie intake, there can be a negative feedback loop where you feel more tired and have less energy. This can make it difficult to stick to your weight loss goals.

Phentermine may help you overcome this by decreasing fatigue and increasing energy levels.

Reduced hunger

One of the main reasons people use Phentermine for weight loss is because it reduces hunger. Hunger is caused by the release of a hormone called ghrelin in the stomach.

Ghrelin signals the brain that you’re hungry and need to eat. When you take Phentermine, it reduces the levels of ghrelin in your body, leading to decreased hunger.

But altering the levels of neurotransmitters is generally not considered a sustainable way to lose weight, which is why Phentermine is typically only prescribed for short-term use.

Increased metabolism rate

Phentermine also increases your metabolism rate by stimulating the release of norepinephrine. Norepinephrine is a hormone that’s responsible for the fight-or-flight response. This hormone increases your heart rate and blood pressure, which in turn amplifies the rate of metabolism.

When your metabolism increases, your body burns more calories at rest and during physical activity. This can lead to weight loss.

What are the side effects of Phentermine?

Phentermine is associated with a number of potential side effects, including:


When the levels of norepinephrine and dopamine are increased, it can lead to feelings of anxiety. This is more likely to occur if you’re taking a high dose of Phentermine or if you’re sensitive to stimulants.

Generally, this triggers other symptoms as well like mood swings and even depression.


Being a CNS stimulant, Phentermine can also cause insomnia. This is because the increased levels of norepinephrine and dopamine can cause trouble sleeping. If you’re struggling to sleep after taking Phentermine, you should speak to your doctor about switching to another drug. Even half dose can cause insomnia.

Dry mouth

Phentermine may also cause dry mouth. This is because the increased levels of norepinephrine lead to reduced saliva production. Saliva is responsible for keeping your mouth moist.

The dry mouth can last for the duration of Phentermine treatment. You can manage this side effect by drinking plenty of fluids and chewing sugar-free gum.


Another common side effect of Phentermine is nausea. This is because when the levels of neurotransmitters are altered, it can lead to an upset stomach.


Phentermine is also associated with headaches. This is because the increased levels of norepinephrine can lead to feelings of tension and tightness in the head.


Phentermine may also cause dizziness. This is because the increased levels of norepinephrine can lead to reduced blood flow to the brain. Even half a pill can trigger these side effects. There are potential drug interactions too. So, if you are on prescription drugs, you may have to rule out a drug combination related allergic reaction.


Probably, the biggest concern with Phentermine is that it’s associated with addiction. Amphetamines are known to be addictive drugs. And, when used for long periods of time, they can lead to tolerance and dependence.

This means you need to take higher doses of the drug to experience the same effects. And, if you stop taking Phentermine suddenly, you may experience withdrawal symptoms, such as depression and fatigue. Most people gained weight right back.

It’s important to note that Phentermine is only meant to be used for short-term weight loss. If you take it for longer than a few weeks, you’re at risk of developing tolerance, dependence, and addiction. Will you be able to develop healthy eating habits in this short span? You are better off with something that supports you to eat healthily and comes with fewer side effects.

Phentermine Reviews – What do customers feel about it?

When you look up for Phentermine reviews, you’ll mostly find positive reviews about it. There’s no doubt that Phentermine works. But when you read these reviews, you need to keep in mind that it’s mostly written by clinically obese men and women, who were struggling to lose weight.

And, when you look at the reviews written by healthcare professionals, they are mostly mixed. This is because they understand the risks associated with Phentermine. Also, they’ve seen people develop tolerance and dependence on Phentermine.

If you look up for Phentermine addiction on messaging boards, you’ll find entire threads dedicated to people who are struggling to quit the drug.

So, when you’re reading Phentermine reviews, you need to keep in mind that it’s an effective weight loss drug. But, it also comes with a risk of addiction and other serious side effects.

Phentermine Cost

Phentermine is a Schedule IV controlled diet pill. This means it’s a prescription-only drug. You need a doctor’s prescription to acquire the drug in the US.

The average cost of Phentermine is around $100 for a month supply. But, if you’re using a mail-order pharmacy, you can get it for as low as $50. But most people who use the drug are not clinically obese.

They use black market pharmacies to obtain the drug. Black market phentermine can not only be expensive but there’s a risk of it being counterfeit.

Is Phentermine worth it – Our thoughts

That depends on several factors. There’s absolutely no question about it, that Phentermine is an effective drug for losing weight and preventing weight gain. It is one of the strongest synthetic chemicals that you can ever use, after all.

But, what you need to ask yourself, is do you even need Phentermine?

Are you obese?

Are you clinically obese with a BMI of 30 or more?

Do you have a weight-related health condition such as diabetes, sleep apnea, or hypertension? Have you tried to lose weight with exercise, diet, and natural weight loss supplements?

If the answer is no to all of the above, then chances are that you won’t be prescribed Phentermine. You can lose more weight without drugs. And, you should only be using Phentermine as a last resort.

Can you get a valid prescription for Phentermine?

If you want to use Phentermine, you need a valid prescription from a licensed healthcare professional or a weight loss clinic.

You can not get a valid prescription for Phentermine online. And, if you’re thinking about using an online pharmacy to prescribe phentermine 37.5 mg, you should know that most of them are operating illegally.

The only way to get a valid prescription for Phentermine is to see a licensed healthcare professional in person. They will conduct a thorough analysis and only prescribe it to you if you have a BMI of 30 or more.

Buying from the grey market may not be worth it

When normal fitness enthusiasts cannot get a valid prescription for Phentermine, they may seek out the drug on the grey market.

Buying Phentermine without a prescription is illegal in most countries, and there are dangers associated with doing so. For one, you cannot be sure of the quality or purity of the drug you’re getting.

There’s a distinct possibility that the drug you’re taking is counterfeit, and even if it’s not, you have no way of knowing what fillers or other substances have been added to it. Some people have reported chest pain after taking the counterfeit diet pills.

Additionally, the person selling you the drug is likely doing so illegally, and you could get in trouble just for buying it.

Phentermine Reviews – Our thoughts

Phentermine is a powerful weight loss supplement that can help you with losing weight in the short term. But it’s certainly not the only option out there, and it may not be the best choice for everyone. If you are not obese, you do not even qualify for it.

If you’re thinking about using Phentermine to lose weight, we recommend talking to your doctor first to see if it’s right for you. And if you do decide to use it, be sure to buy it from a reputable source.

Alternatives to Phentermine

If you’re not obese, or if you’re not willing to accept the risks associated with Phentermine, there are other options available.

You can try natural weight loss supplements such as PhenGold, Leanbean, and PrimeShred.

#1 – PhenGold – Comprehensive Weight Loss Tool


Despite all the popularity, Phentermine is in reality a one-trick pony. It suppresses your appetite, but it does little else to help you lose weight.

PhenGold is different. It’s a comprehensive weight loss tool that not only suppresses your appetite but also helps you burn fat, boost your metabolism, and increase your energy levels.

The result is rapid and sustainable weight loss. Almost forgot to mention that PhenGold is 100% natural and hence, does not cause any of the side effects associated with Phentermine.

Why PhenGold is a better tool for your weight loss journey

You cannot put a definite time frame on weight loss. There are so many factors that will influence your ability to lose weight. Your overall health, metabolic fluctuation, lack of energy, and your body chemistry to name a few.

With PhenGold, there’s no short term weight loss hack. You lose weight gradually, but surely and the result is sustainable.

Green Coffee Bean & Green Tea for energy and metabolism

PhenGold contains Green Coffee Bean, which is a natural source of caffeine. Caffeine is a well-known energy booster, and it also has thermogenic properties.

This means that it can help you burn more calories, even when you’re at rest. It also contains chlorogenic acid, in case you are unaware. Chlorogenic acid is a naturally occurring compound that can help you lose weight by preventing the absorption of fat.

At the same time, PhenGold also contains Green Tea. Green Tea contains EGCG, which is a powerful antioxidant. Antioxidants are important for overall health, but they can also help you lose weight by reducing inflammation.

Cayenne Pepper and Caffeine Anhydrous for thermogenesis

PhenGold contains two powerful thermogenic ingredients – Cayenne Pepper and Caffeine Anhydrous.

Cayenne Pepper is a well-known fat burner. It helps you lose weight by increasing your body temperature, which in turn, causes you to burn more calories.

Caffeine Anhydrous is simply caffeine with the water removed. This makes it more potent and hence, more effective at helping you lose weight.

L-Tyrosine and DMAE for mood, B vitamins for energy

Most users who use PhenGold mention that they have so much energy. That’s because of the B-vitamins present in it.

B-vitamins are essential for energy production, and they can also help you lose weight by reducing fatigue. At the same time, PhenGold contains L-Tyrosine, which is an amino acid that’s known to improve mood. This is important because a good mood can help you stick to your weight loss goals.

PhenGold Price

PhenGold is very reasonably priced at just $59 for a month’s supply. That’s very reasonable considering that it contains such high quality and potent ingredients.

You can buy a 2-month pack and get the third month for free for just $119. You get a 60-day money-back guarantee too. So, in case it doesn’t work for you, you can get a refund straight away.

Conclusion – Is PhenGold worth trying?

PhenGold is a natural weight loss supplement that can help you lose weight by curbing hunger, optimizing your RMR, and increasing your energy levels. It’s also thermogenic, which means it can help you burn more calories.

We don’t see a single reason to try out something like Phentermine when you have this option.

#2 – Leanbean – Eat 1000 Calories Less Every Day


Any smart fitness coach will tell you that losing weight is all about calories in vs calories out. So, the best way to lose weight is to eat less and exercise more.

In theory, this is very simple. But in practice, it’s much harder because hunger can get in the way. This is where Leanbean comes in. It’s a natural hunger curbing supplement that can help you eat up to 1000 calories less every day.

Why Leanbean can help you eat healthy

Leanbean contains a combination of 11 different ingredients that have been clinically proven to help with weight loss. Each one of these addresses a different aspect of weight loss.

Reducing your calorie intake

Leanbean contains 3 grams of glucomannan, which is a fiber that can help you feel full for longer. Glucomannan is 100% natural and extracted from the root of the Konjac plant.

It works by absorbing water and expanding in your stomach, which makes you feel full. This can help you eat less and lose weight. At the same time, it also contains chromium, which is a mineral that can help reduce hunger cravings. It does this by helping to regulate your blood sugar levels.

With almost 1000 calories less, the average weight loss people experience on Leanbean is 1-2 lbs. a week.

Burning body fat

Your metabolism, or your body’s ability to burn calories, plays a big role in weight loss. The higher your metabolism, the more calories you’ll burn, and the easier it will be to lose weight.

Leanbean does not use conventional stimulants to amplify your RMR. Instead, it uses gentle ingredients like Turmeric and a blend of B Vitamins, which can help you lose weight by helping your metabolism function at its optimum.

Turmeric is a spice that’s often used in Indian cuisine. It contains a compound called curcumin, which has been shown to have thermogenic properties. This means it can help you burn more calories and lose weight.

Keeping your energy levels high

Your energy balance is another important factor in weight loss. If you have more energy, you’ll be able to exercise more and burn more calories.

Leanbean contains a combination of caffeine and green coffee bean extract, which can help increase your energy levels and make it easier for you to lose weight.

Leanbean also contains B vitamins which, as we mentioned before, are essential for energy production. So, by optimizing your B-vitamin levels, Leanbean can help you have more energy and lose weight.

Leanbean Pricing

Despite being the #1 fat burner for women in the UK, Leanbean is priced at just $59.99 for a 30-day supply. You can buy the three-month package, which gives you an additional month for free.

#3 – PrimeShred – Burn Fat 24/7


PrimeShred was designed as a tool to help men and women lose weight fast. We know that fast weight loss is looked down upon by some in the fitness industry, but we also know that not everyone has the same weight loss goals.

Sometimes people want to lose weight quickly for an event, like a wedding or beach vacation. Other times, people have been struggling to lose weight for years and just need a boost to finally start seeing results.

That’s where PrimeShred comes in. It’s a powerful fat burner that can help you lose weight quickly and effectively.

Why PrimeShred can help you with weight loss

PrimeShred is a wholesome weight loss supplement that does more than just help you lose weight. It also helps you burn fat, increase your energy levels, and improve your mood.

Here’s how it can help you better than Phentermine with weight loss.

Burns Fat 24/7

The biggest hurdle that people face while trying to lose weight is a sluggish metabolism. A slow metabolism means that your body is not burning fat as efficiently as it should be.

PrimeShred contains a powerful blend of thermogenic ingredients that can help you burn fat around the clock. This means that even while you’re sleeping, PrimeShred will be working to help you lose weight.

There’s the natural caffeine in Green Coffee and Green Tea, as well as caffeine anhydrous.

Break down stored body fat

Finding it tough to lose those stubborn layers of body fat? PrimeShred can help.

It contains a powerful ingredient called Rhodiola, which has been shown to help the body break down stored body fat and use it for energy.

This means that you’ll not only be burning more fat, but you’ll also have more energy to get through your day. Most men and women who use PrimeShred are able to see visible abs in a span of weeks.

Keeps you calm and relaxed

If you have been feeling frazzled and stressed out, it can make it harder to lose weight. That’s because stress can lead to cortisol spikes, which can promote fat storage.

PrimeShred contains an ingredient called L-Theanine, which is an amino acid that can help you feel calm and relaxed. It also contains DMAE, which is a compound that has been shown to help reduce stress.

PrimeShred Pricing

PrimeShred is priced at $49.99 for a 30-day supply, which is on the lower end as far as fat burners go. You can also buy the 90-day supply, which gives you a 3-month supply for just $99.99.
