Phentermine Over The Counter: Are There Any Truly Effective OTC Alternatives?

Let me guess; you’ve been trying to get phentermine over the counter, but it’s just not working out.

Do any of these sound familiar?

  • You contacted several weight loss clinics, asking if they offer phentermine
  • Maybe you had a consultation with a clinic, but they said you didn’t qualify
  • Lastly (and I hope not) you tried to buy real phentermine online without a prescription… and you likely lost several hundred dollars to some company in Cyprus.

You’ve now discovered that Phentermine over the counter is not an option. These diet pills require a prescription from a licensed doctor. So now you’re looking for effective alternatives to phentermine. Maybe you’re frustrated by the sheer number of products claiming to be like phentermine, without any real science or results to back up the claims.

I’m here to reveal the truth to you.

The Truth About Phentermine Alternatives

The sad reality here is that it’s most phentermine alternatives are just various combinations of the same old natural supplements that you see being advertised online by shady companies with questionable products and questionable billing practices.

How many times have you taken a chance and put your trust in a new diet pill or weight loss supplement, only to be completely let down by it? Millions of people try to lose weight with over the counter supplements.

These range from the use of an appetite suppressant to diet pills that boosts the metabolism.

I want to ask you… Have you tried any of these?

  • Hoodia
  • Raspberry Ketone
  • Resveratrol
  • Garcinia Cambogia
  • Green Coffee Bean
  • Green Tea
  • and many more…

If you said yes to any of those, and you got a little feeling of frustration, I understand and I feel for you.

Are There Effective Phentermine Alternatives?

The goal of this post is to help you better understand which Phentermine alternative works. I will guide you through important factors to consider when looking at natural diet pills, ensuring you understand exactly what to look at.

Phentermine is one of the most well-known weight loss pills, but not everyone can use it. Some people may not be eligible for Phentermine, but still need help to slim down, while others want to use something that won’t give them side effects that are associated with this weight loss drug.

Regardless of the group of people to which you belong, the chances are PhenterPro SR is the solution you need. What makes this Phentermine alternative an effective solution, and why does it continue to grow in popularity? Scroll down to find out.

Phentermine Over The Counter: What Are The Alternatives?

For many people, getting their hands on Phentermine can be a challenge. There’s no way to walk into a pharmacy and buy Phentermine over the counter. You might have tried getting in touch with local weight loss clinics, only to find out that you do not qualify for a prescription. Perhaps you went to a physician, and they either do not provide prescriptions for Phentermine, or you didn’t meet the minimum criteria.

Buying Phentermine Without Prescription

Then there are the many online stores that claim to sell Phentermine without the need for a prescription. This could easily cost you hundreds of dollars and they are all scams (it’s a federal offense to sell phentermine without a prescription).

These companies are typically based in countries like Cyprus and they either send you placebo pills or ship nothing at all and keep your money.

Turning To The Alternatives

Going through all of these steps can be frustrating. Then you find an alternative to Phentermine – a diet pill that makes similar promises. The only problem is, many of these diet pills do not work nearly as effective as Phentermine – focus on the word “many.”

If you have tried Raspberry Ketone supplements, green tea, garcinia Cambogia, hoodia, and similarly hyped up supplements, without experiencing any real results, then understand that you are not alone.

There are many reasons for these Phentermine alternatives to failing. One common issue with over the counter diet pills is the fact that they do not combine the right ingredients. Sometimes, an appropriate formula is featured by these dietary supplements, but the concentrations of the ingredients are too low. This means the supplement may not effectively curb food cravings and help with the fat burning process.

Today, we are here to tell you about one phentermine alternative that is proven to provide you with benefits, without being a frustration in your life. We will take a look at what Phentermine is, what the supplement does to your body, and what this one particular alternative to this weight loss drug could do for you.

Phentermine: How does it work?

Phentermine is a prescription weight loss medication sold under brand names such as Adipex, Lomaira, Suprenza, Ionamin, and Pro-Fast. The drug was approved by the FDA back in 1959 for short-term use of up to 12 weeks for people older than 16. Phentermine is not a “regular” weight loss pill due to the fact it is mainly prescribed for obese men and women whose BMI 30 or larger.

In some cases, Phentermine is prescribed to people with BMI 27 if they have obesity-related problems such as high blood pressure, type 2 diabetes, and high cholesterol.

Phentermine And Diet

Phentermine, which comes in the form of a tablet or capsule (1), is prescribed as an adjunct to a low-calorie diet for weight reduction. Not everyone can get a prescription for the drug as doctors mainly prescribe it to individuals who have not succeeded to lose weight through diet and regular exercise alone.

The mechanism of action through which Phentermine works is simple and straightforward; it belongs to the class of drugs called anorectics or appetite suppressants. This weight-loss drug increases the release of neurotransmitters dopamine, serotonin, and norepinephrine, which stimulate metabolism and suppress appetite.

Phentermine As An Appetite Suppressant

In other words, Phentermine decreases food intake by making a person feel full for longer. Many cases of obesity are associated with overeating, and Phentermine can help users solve that problem (2).

As mentioned above, Phentermine is not meant to be a long-term solution for weight loss. In fact, many people build a tolerance to the drug within a few weeks. This is why many people are looking for Phentermine alternatives. Not only does your body gain a tolerance, but there also develops a risk of misuse. Once the weight loss pills no longer seem to work, the person feels like they need to take a higher dose. Without medical supervision and advice, this can lead to dangerous side-effects caused by the weight loss medication.

Is Phentermine really effective?

Various studies have analyzed the efficacy of Phentermine. A study from the journal Circulation reported that the expected average weight loss with phentermine use is 5% of the initial body weight. Over 12 weeks (the most common duration of phentermine use) people tend to lose up to 10% of their initial body weight meaning a person who weighs 200lbs (90.7kg) can lose 10 to 20 lbs (4.5 to 9kg) (3).

Additionally, Yonsei Medical Journal published a study that demonstrated that subjects from the phentermine group lost more weight and waist circumference than their counterparts from the placebo group.

A significant number of participants lost about 5% of their initial body weight while others lost 10% or more. Scientists concluded that short-term use of Phentermine poses as an effective weight loss measure in obese but otherwise healthy individuals (4).

While many studies show that Phentermine is effective for weight loss on its own, the drug gives the best results when used in combination with other medications such as topiramate.


Your healthcare provider is the one who must prescribe an adequate dosage for your specific needs as a patient. It’s not recommended to take more or less than recommended by your doctor.

Before 2016, the available doses of Phentermine were 15mg, 30mg, and 37.5mg. But in 2016, the FDA also approved 8 mg Phentermine. Bigger doses are taken once a day while the lowest dosage of Phentermine is usually taken three times a day. The drug is usually taken one hour before breakfast or one to two hours after breakfast.

Side effects of Phentermine

Even though Phentermine can lead to a successful weight loss, the drug also has some side effects. The most common adverse reactions (5) that men and women report are:

  • Constipation or diarrhea
  • Dizziness
  • Dry mouth
  • Fatigue
  • Flushing of the skin
  • Heart palpitations
  • Irritability
  • Jitters
  • Nausea
  • Sleeping disturbances
  • Vomiting

Phentermine can blur your vision and make you drowsy. The drug should not be taken by pregnant women and people with serious heart disease and other health problems. It’s worth mentioning that Phentermine may have an addictive effect, although the risk of addiction is low.

Phentermine Drug Interactions

There are also interactions to consider when looking at these weight loss medications.

People who already take drugs to help with certain diseases may experience an increased risk of side-effects. This can even occur when the person combines Phentermine with natural alternatives. The natural ingredients and the chemicals used in this prescription medication may yield an interaction.

PhenterPro SR: what is it and how does it work?

Phentermine is a well-known weight loss drug, but it is not everyone’s cup of tea. You are also not allowed to buy Phentermine over the counter. For example, some people are not eligible for Phentermine, but they still can’t lose weight on their own. There are also some men and women who have tried Phentermine and want to avoid the side effects they have experienced.

A common misconception is that there is no adequate replacement for Phentermine, but the reality is entirely different. PhenterPro SR poses as a viable weight loss solution worth considering. As an alternative to Phentermine, this product claims to offer similar effects, without some of the more serious side-effects.

These diet pills primarily take advantage of natural ingredients. By using such ingredients, these Phentermine alternatives offer a safer option for people who need appetite suppressants and those who wish to experience an increase in fat burning.

What is PhenterPro SR?

PhenterPro SR is a natural dietary supplement. As a Phentermine alternative, this one can actually be obtained without a prescription. The weight loss supplement was developed with the main objective to produce similar effects and benefits as the well-known prescription-strength drug, but without adverse reactions associated with it.

PhenterPro SR is mainly used as a multifunctional product that helps men and women slim down in a natural way. It works by suppressing the appetite and boosting energy levels. As a result, you eat less, feel full for longer, and at the same time, you get the maximum out of your workout regimen.

Just like Phentermine, PhenterPro SR is used in conjunction with diet modifications and regular exercise. Both the suppression of appetite and energy boost is vital for successful weight loss.

Benefits of PhenterPro SR

What makes this weight loss pill so “great” except the fact that you can get it without a doctor’s prescription?

Let’s take a look at some of the many reasons you might consider utilizing these diet pills in your weight loss journey:

  • Energy boost
  • Curbs appetite
  • Makes it easier to do intermittent fasting
  • No late-night snacks
  • No jitters and stress
  • Better mood
  • Faster metabolism
  • Improves body composition in the most stubborn areas such as the stomach, flabby arms, hips, love handles, thighs, neck, and face
  • Reliable
  • Safe to use
  • Natural formula

PhenterPro SR ingredients

As seen above, PhenterPro SR has tons of benefits, but it’s impossible not to wonder what makes this diet pill so effective. The key to PhenterPro SR’s efficacy is the potent formula which consists of the following ingredients:


1,3,7-trimethylxanthine may seem like a complicated term, but the ingredient itself is known to all of us – it’s caffeine. The truth is that caffeine has been demonized for years, although it has multiple health benefits. What’s more, caffeine can help you slim down. For example, a study from the Critical Reviews in Food Science and Nutrition found that caffeine promotes a reduction in weight, BMI, and body fat (6).

The Obesity Research journal published a study which discovered that high caffeine intake was associated with weight loss through thermogenesis and fat oxidation and with suppressed leptin in women (7). Leptin is a hormone that controls appetite by signaling the brain to stop eating. It also helps the brain regulate how much energy the body burns throughout the day. When it comes to caffeine, it’s important not to go overboard. That’s why PhenterPro SR proves to be so useful – it delivers just the right amount of caffeine to promote weight loss.


Hordenine is a chemical naturally found in barley, and its structure is similar to stimulants such as those found in bitter orange. Besides, barely, hordenine is also found in algae, cacti, and some grass species. Hordenine is widely used in weight loss supplements and products for the improvement of athletic performance. Adrenergic hordenine causes nerve cells to release the neurotransmitters adrenaline (epinephrine) and noradrenaline (norepinephrine).

In turn, it boosts energy levels. Studies show that hordenine increases energy expenditure, which can lead to weight loss (8). Also, supplementation with hordenine can suppress appetite and aid fat loss, which can be quite stubborn. Hordenine increases cellular metabolism to enhance mental focus and also promote fat burning. The chemical helps in the breakdown of fatty acids and boosts metabolic rate, slows down digestion and the human body’s gastric emptying, thus lowering appetite. At the same time, hordenine balances the adrenal glands’ output to increase motivation and improve mood.


2-phenylethylamine (PEA) is an organic compound and trace amine which acts as a nervous system stimulant in humans. Besides humans, PEA is also found in chocolate, algae, fungi, bacteria, various plant species, Korean natto, and commercial eggs.

Similarly to other ingredients of PhenterPro SR, PEA also increases the levels of neurotransmitters such as dopamine, histamine, serotonin, epinephrine, and norepinephrine (9). How can it help you lose weight? 2-phenylethylamine produces natural high or feeling of euphoria that improves mood and helps combat depression and stress. Through improved mood, PEA can also reduce appetite and make sure you eat less. It’s also worth mentioning that PEA can improve glucose control, which is significant for weight management.


Synephrine is a naturally occurring chemical found in the peels of citrus plants such as Seville or bitter orange. This chemical affects the body’s energy production by altering the function of the liver, which produces enzymes that take part in digestion and energy levels in the body. Synephrine has become a popular ingredient in supplements for weight loss and athletic performance. Additionally, synephrine prevents the conversion of sugars to fats, and it increases metabolic rate. A study from the International Journal of Medical Sciences discovered that subjects who received 50 mg synephrine burned 65 calories more than participants in the placebo group in the first 75 minutes after taking the supplement (10).

Moreover, Phytotherapy Research featured a study which found that subjects given synephrine burned more fat as opposed to carbs during exercise (11). Synephrine is particularly effective when used in combination with caffeine, which is exactly what makes PhenterPro SR so powerful.

Journal of the International Society of Sports Nutrition published a study which showed that synephrine alone and in combination with caffeine increases the number of repetitions and maximum weight load when performing squats when taken 45 minutes before exercise (12). In other words, synephrine can reduce your appetite and give you more energy while allowing you to get the most out of your workout routine. Let’s not forget that synephrine elevates mood and exhibits anti-inflammatory and antioxidant effects.

Therefore, PhenterPro SR can

  • Lower body fat percentage
  • Cause steady weight loss
  • Make you more energetic
  • Improve athletic performance
  • Keep you feel full
  • Improve your overall health and wellbeing, quality of life


An important role in the effectiveness of PhenterPro SR is reserved for proper intake. If you want the diet pill to work, it’s needed to take it properly. For the best results, it’s necessary to follow Lipotropic 16:8 diet and eating schedule and take 1 PhenterPro SR tablet after waking up. Make sure you drink plenty of water, or you can take some black coffee, but avoid eating four to six hours after waking up in the morning. Then, eat the first meal of the day and take another PhenterPro SR pill with that meal.

Starting With A Smaller Dose

Ideally, you should start with two tablets in order to assess your results, tolerance, and whether it’s working for you. Starting with a smaller dose is always better and safer. If necessary, you may increase the daily dose to four pills.

What if I miss the dose?

Under perfect circumstances, you should make sure to take PhenterPro SR regularly, every day at the same time. But, if it happens that you miss the dose, you should not double the next dosage. Just continue taking the tablets as you normally would if the dose weren’t missed.

Are there side effects of PhenterPro SR?

Thanks to the all-natural formula PhenterPro SR is safe for general use. Unlike Phentermine, which has uncomfortable side effects and gives people jittery feelings, PhenterPro SR has no adverse reactions. In fact, one of the biggest reasons why people use PhenterPro SR is that they experience no side effects. This makes the option a great choice for people who discover they can’t get Phentermine over the counter.

It’s worth mentioning that some users may experience trouble sleeping first two or three nights. People usually experience a better mood and more energy, thanks to PhenterPro SR. What this essentially means is opting for this particular Phentermine alternative gives a person a safer way to lose weight, compared to the prescription option.

Interactions With Prescription Drugs

While these OTC diet pills are safe, it is important to be wary when you are taking other prescription medications. If you take drugs for high blood pressure, talk to your doctor about the ingredients in these Phentermine alternatives. This will help you get a better idea of whether the weight loss medications could potentially result in interactions.

Allergies And Sensitivities

Do not forget to consider your own sensitivities and allergies when looking at alternatives to Phentermine diet pills. The ingredient list of the over the counter diet pills will be handy in this case. Make sure you understand your own allergies. Then ensure the natural weight loss drugs you want to use do not contain these ingredients. When looking at Phentermine alternatives, with the goal of reducing your body mass index, take note of your sensitivities too. Some people are sensitive to caffeine found in supplements, for example. In this case, consider other diet pills that does not contain this particular stimulant.

Should I Take A Break From PhenterPro SR?

You may start noticing results within two weeks, however most people notice changes within the first month. Ideally, you should take PhenterPro SR three months and take a month-long break before you start using it again.

The conclusion here is to avoid looking for Phentermine over the counter. Websites that promote these prescription weight loss drugs as OTC medications will likely send you a Phentermine alternative.

When buying natural diet pills, make sure you look at the ingredients. Losing weight might be your goal, but your own well-being should be the top priority when using these supplements. Make sure you understand how the over the counter diet pills work. An appetite suppressant should be able to reduce your cravings and keep you feeling full. Phentermine alternatives that causes a thermogenic effect should help you burn fat faster.
