Phentermine 37.5mg tablets from Mutual and Able Pharmaceuticals. These A-159 and Mutual MP-273 phentermine tablets were among the most popular for their potency and consistent quality.

The strongest available form of phentermine is the 37.5 mg tablet. Phentermine 37.5 also happens the be on the most popular forms due to its effectiveness in terms of weight loss. It provides a significant boost in energy while adequately suppressing your appetite.  As a result, most physicians will hesitate before they consider prescribing it to patients.

There are many reasons for this, including drug interactions.

What Are Phentermine 37.5 mg tablets?

Phentermine 37.5 mg tablets are merely the generic version of the brand name (and more expensive) Adipex, which is manufactured by Teva Pharmaceuticals. In this post, we help you get a better understanding of what Phentermine 37.5 means for those who want to lose weight. The weight loss effects of the pills are provided due to various actions that the active chemicals have in the body.

These pills work primarily as a stimulant in your body. They help to boost your energy, which assists in improving your performance and motivating you to exercise. They are classified as norepinephrine reuptake inhibitors (1).

The stimulant also acts as an appetite suppressant. This means you will feel fuller. In turn, you reduce your risk of overeating or binging during the day.

The drug information related to Phentermine generally advises a healthcare provider to prescribe the medication. The drug cannot be used with certain medications.

A practitioner who focuses on trustworthy health information will take your personal data into consideration. The healthcare professional will then decide on a typical dose for your case, while also aiming to minimize the risk of adverse effects.

Why is it so difficult to get a prescription for phentermine 37.5 mg tablets? 

Prescriptions Sign On A Drug Store Front

The sale of prescription medications online boomed during the early 2000s when “online consultations” were a new and coming venture. Phentermine was one of the most common weight loss drugs prescribed at this time.

It allowed patients to complete online medical forms with requests for treatment from licensed physicians.

These physicians could then approve or deny treatment. All of this was being done without a doctor.

A doctor should provide medical advice, consider interactions with other drugs, and then decide of this is a good option for the patient. When all is considered safe, and the body weight of the patient puts them at a BMI of 30 or higher, then the doctor can consider a prescription for these weight loss drugs.

While it may have seemed like a better way of managing the healthcare crunch of not having enough physicians, it created an online prescription medication nightmare.

False Information Leading To Inappropriate Prescriptions

Eventually, some patients began inputting false information in order to be approved for controlled medications such as narcotics and dietary supplements.

Within time, online consultation groups and online pharmacies were shut down.

To provide medical advice toa patient, they need to see a doctor – as this allows for a more effective physical examination.

Doctors were originally lured with very profitable payouts for blindly writing prescriptions (mostly controlled substances) to individuals they had never met.  And some patients were manipulating others to write prescriptions that no doctor would agree to do if provided correct information.

So of course, this quickly became dangerous territory for not only the patients but the healthcare system as a whole.

When using these prescription drugs without a doctor’s supervision, a person puts themselves at risk.

Those with high blood pressure may experience a worsening of their symptoms (2).

This is especially the case with uncontrolled high blood pressure, which is one of the risk factors for coronary artery disease.

These drugs called sympathomimetic amines comes with risks and side-effects. By choosing to use an online service, the patient’s medical history is not taken into consideration. Taking an overdose may even result in the need to contact a local poison control center.

If you wandered onto this page and are still reading, it is obvious you’re interested in Phentermine 37.5 mg tablets. But let us explain. 

The federal government has long since banned the sale of online phentermine; the remaining “online pharmacies” still operating to this capacity are usually advertised as being in small foreign countries.

Regardless of where these pharmacies identify themselves to be, you should still be leery of purchasing anything online for consumption.

Products can be placebos or actually toxic to the body, and toxicology testing would typically be needed to identify the components of these items.  And on top of that, they do not hesitate in charging hundreds of dollars in addition to shipping. Ultimately, payment does not even guarantee that you will receive the advertised product.

What Are The Risks Of Phentermine?

There are important reasons why doctors are often against the idea of prescribing Phentermine to a patient.

This is often due to the effect on blood pressure, as well as other risk factors of serious diseases, that are linked to Phentermine (3).

Common side-effects that people experience when using this drug for weight loss include dry mouth, dizziness, and nausea. Sometimes, vomiting occurs, as well as digestive troubles – which can include constipation or diarrhea.

Due to the stimulatory effects of Phentermine, it is possible to experience irritability, as well as sleeping problems when using the drug. This can keep you awake at night, further aggravating side-effects like irritability.

Effects Of Phentermine On Sleep

Poor sleep can also have an adverse effect on your weight loss results, as well as your overall wellbeing. Sleep deficiency is linked to high blood pressure, for example. Insomnia is a relatively common side-effect of phentermine (4).

This, in turn, can result in problems like chest pain when the pressure starts to damage arteries.

When your pressure rises, you also run a risk of other complications, such as primary pulmonary hypertension. The decreased ability to pump blood through the body, which is caused by the increased blood pressure, can also cause fatigue and heart palpitations.

What Are The Alternatives?

PhenterPro SR As An Alternative To Phentermine

PhenterPro SR was newly developed to obtain the goal of boosting energy, suppressing appetite, and weight loss without the potentially dangerous side effects of phentermine 37.5 mg.

Instead of using pharmaceutical chemicals, this alternative rather turns to natural ingredients to give you a safer option to lose weight.

Many people have experienced effective weight loss with this alternative.

Differences In Mechanism Of Action

As you can determine from the information above, PhenterPro works in a similar way as Phentermine to help with weight loss.

The big difference lies in the ingredients.

While Phentermine uses synthetic chemicals for weight loss, PhenterPro avoids the use of such ingredients.

Your body must first adjust to the new drug; however, the best way to lessen the chances of developing a headache is to drink water.

It is recommended to consume an 8oz glass of water when taking it in the morning.

PhenterPro is also less likely to cause problems and interactions with other drugs.

There is the risk of allergic reactions, but this is extremely rare. PhenterPro gives you a complete overview of the ingredients used in the formula.

When using the drug to lose weight, you know exactly what you put in your body. This also ensures you can determine whether there are any ingredients you may be allergic to. This helps to reduce the risk of an allergic reaction. Consider medical help if you are taking other medications.

You should also avoid taking high doses, especially with other stimulants. If you do use other drugs, consider possible interactions. Take a complete list of your medications to a doctor. They can help you determine whether you would run a risk of serious side effects.

The PhenterPro Formula

As we mentioned, PhenterPro rather uses natural ingredients to aid with your weight loss journey. With this in mind, it is important that we take a closer look at the ingredients. By analyzing the natural extracts inside each capsule, it’s easier to see how the pill may help you weight weight loss.

1,3.7 Trimethylxathine

While the name may sound a bit strange, this is one of the key ingredients. The ingredient is essentially caffeine, but a very potent form (5).

You get a boost in energy with this ingredient, and you’ll experience a faster metabolism. This ingredient has also been shown to reduce the risks of metabolic syndrome – which means it protects against heart disease, diabetes, and more.


This is a multipurpose ingredient that helps with several factors, such as:

  • The regulation of blood sugar levels
  • Enhances metabolism, resulting in a fat burning effect
  • Enhances your memory and focus
  • Improved mood and reduced symptoms of depression

In addition to these benefits, you also don’t have to worry about building up a tolerance to 2-Phenylethylamine (6).


Another important ingredient is synephrine, which is an extract from what is known as the bitter orange. This ingredient has been shown to help enhance the fat burning process of the body.

While effective, the ingredient does not cause an increase in eighter your blood pressure or heart rate.


An extract from the barley plant, this is an adrenergic ingredient. The ingredient results in the release of two specific neurotransmitters, known as noradrenaline and adrenaline.

You experience a surge in energy, reduced hunger, and faster fat burning with this particular ingredient.

Making The Most Out Of PhenterPro

PhenterPro is not a pharmaceutical drug. This means there isn’t a risk of drug abuse. With Phentermine 37.5 mg, however, drug abuse has been noted multiple times.

PhenterPro is as effective at helping you lose weight as you make it. One or two doses may be needed, depending on your situation.

Does PhenterPro Cause Weight Loss On Its Own?

Similar to Phentermine 37.5 mg, you may need to put in effort from your side for the supplement to work effectively too.

Fortunately, you can use this supplement for more than just a few weeks.

With Phentermine, on the other hands, you are only allowed to use it for a few weeks – long-term use can cause complications.

Another major benefit is the fact that you don’t have to worry about withdrawal symptoms, even with a missed dose.

Focusing On Diet And Exercise

To maximize the benefits you get from PhenterPro, you may need to implement a low calorie diet alongside the supplement.

Variety of Dishes

In addition to your diet, make sure you look at how much you exercise too. You should expend more calories than you eat – this is generally considered the foundation for weight reduction.
