The most widely prescribed weight loss pill is Phentermine. It is a drug classed medication for the very overweight and obese. It is not available without a prescription so a big market for alternative or over the counter Phentermine has been created.

Where can you get Phentermine over-the-counter for sale in stores. Are there other products that produce similar results?

Why Choose a Phentermine Over-the-Counter Alternative?

The prescription appetite suppressant, Phentermine, is one of the most talked about weight loss drugs in the world. However, although plenty of people are sharing their Phentermine success stories, there’s also a lot of talk about the side effects.

In addition to having potentially life-threatening side effects, Phentermine also poses a threat of addiction. So, although there is no denying the medication works well for some people, it also presents several risks. Adipex (or Adipex-P) is the most popular brand.

  1. PhenQ – Editors Choice
  2. Phen24
  3. PhenGold

The US Food and Drug Administration (FDA) considers the risks are acceptable and has approved the drug’s use as a short-term treatment for obesity.

The governing bodies in many other countries see things differently, stating the potential for good does not outweigh the potential for harm.

Fortunately, people who are unable to get hold of diet drug or are unwilling to risk the side effects have the option of buying over-the-counter (OTC) Phentermine diet pills instead.

All of the best OTC Phentermine pills use natural ingredients that don’t present any of the risks the medication does. They also boast a greater versatility because, in addition to controlling hunger, the similar supplements deliver other useful benefits as well.

The bad news is you won’t find any of the top diet pills similar to Phentermine at your local pharmacy. You can only buy them online.

The good news is, all the best options have incredible success rates and money-back guarantees.

Phentermine Vs the Alternatives: The Main Differences

OTC Phentermine comparables differ from the medication in several ways. The most obvious difference is they are easier to obtain. A prescription is not necessary. Anyone can buy them.

You can also use the OTC versions for a long as you want to. That’s not the case with the original. Doctors are only allowed to prescribe it for a few months.

Weight loss is a long process so that’s not good. It’s understandable though. Let’s not forget, the drug poses a threat of addiction. The longer you take it, the greater the risk of addiction is likely to be.

The obesity medicine is also let down by the fact that it offers such a limited level of weight loss support. All it does is control hunger and, if you don’t respond well to the medication, it may not even do that.

Regardless of what you may have heard, Phentermine does not work for everyone.

It does work in the majority of cases though and, by controlling hunger, the medication makes it easier for you to eat less food without having to endure unbearable hunger.

That’s great. Hunger is a powerful enemy. It can stop a diet in its tracks. If you let your hunger the better of you, your diet will fail.

All the OTC Phentermine’s control hunger too. However, they also speed up your metabolism. This raises your resting metabolic rate, helping you to burn extra calories and fat.

Good OTC appetite suppressants provide help in other areas too and often make dieting easier by warding off fatigue.

One of the main advantages of weight loss supplements that work like Phentermine is the lack of side effects. They help you to lose weight safely without having to worry about high blood pressure or any of the other negative issues Phentermine can present.

Can I Get Phentermine OTC?
Yes, you can get Phentermine-over-the counter with a valid prescription. Stores and vendors in the US such as Walmart, CVS, Costco, Walgreens have phentermine for sale. There are compelling reasons to opt for non drug based comparable diet products though!

What to Look For In a Top Phentermine Alternative

When you are looking for a good diet pills like Phentermine it’s best to avoid Amazon or eBay. Although both the company’s sites sometimes appear to offer respected similar slimming tablets, the diet pills you see there could be fake.

The companies that produce the top weight loss supplements that work like Phentermine create special sites that provide full information about their products and double as online stores. They don’t distribute them elsewhere.

If you fall into the trap of buying a counterfeit product that does not work, you also run the risk of nasty side effects and won’t have the protection of a money-back guarantee.

The best Phentermine substitutes provide ingredients that have proven weight loss capabilities such as glucomannan, capsicum, and green tea.

Because they are produced by reputable companies, you don’t need to worry about undisclosed ingredients or unsafe combinations that may make you unwell.

The companies behind successful products understand the science. They are familiar with the ingredients and know what they can do. That’s why they are confident enough to offers money-back guarantees.

They are also very transparent. Without exception, their product websites explain the value of the individual ingredients and provide clinical references within the text or at the bottom of the page.

The average dieter does not have expert knowledge about natural weight loss ingredients and the things they can do so this type of information is important. When you can check the facts, and see the research for yourself, you don’t have to worry about being misled.

Top OTC Alternatives to Phentermine

Although there is an alarming number of weight loss pills that do what Phentermine does, there are some that fail to be effective for weight loss and side effect free, there are also several good options that work. Without doubt, PhenQ, Phen24, and PhenGold are three of the best.

PhenQ – Best Phentermine Alternative


PhenQ is probably the most highly thought of diet pill in the world. Since its launch in 2015, it’s already helped more than 190,000 men and women to lose weight.

Many people who lose weight with PhenQ are not familiar with the prescription weight loss drug and fail to grasp the significance of the name. The same is true for Phen24 and PhenGold.

However, although it’s the first choice of many people who are looking for a Phentermine substitute, it’s also a good option for anyone who needs help to lose weight.

Reasons to Choose PhenQ

In addition to being a powerful appetite suppressant, PhenQ provides help in so many other areas it’s said to be the equivalent of multiple diet pills rolled into one. If you want to avoid the hunger trap and lose weight as fast as possible, PhenQ is a great option to choose.

PhenQ supports your efforts to lose weight by:

  • Controlling hunger
  • Increasing calorie expenditure and fat burning
  • Blocking the formation of fresh fat cells
  • Enhancing mood
  • Providing extra energy

Key Ingredients

PhenQ provides several respected ingredients including nopal, Capsimax, and a-Lacy’s Reset.

Nopal is a cactus extract that suppresses appetite. Just eating a small chunk of its flesh can ward off hunger for hours. That’s the traditional way to use it. Research shows nopal further supports weight loss by blocking the amount of calories you get from dietary fats. A great inclusion in this Phentermine formula.

Capsimax is a proprietary capsicum extract that’s designed to be gentle on the stomach. It provides a natural fat burner called capsaicin. Research shows capsaicin also suppresses appetite. 

a-Lacys Reset is another proprietary ingredient. It boosts your metabolism and increases thermogenesis, causing your resting metabolic rate to increase.

The results of an early study show that, in addition to supporting rapid fat loss, a-Lacys Reset improves muscle mass. By doing this it can help you to keep the weight off by ensuring your metabolic rate remains high.

Phen24 – Night Time Adipex Substitute


It’s hard not to draw comparisons between Phen24 and PhenQ because PhenQ is the equivalent of several diet pills and, when you buy Phen24, you get two sets of diet pills for the price of one.

Phen24 is a two-step weight loss system that works better than Phentermine and offers weight loss support night and day. It achieves this by providing two different formulations – Phen24 Day and Phen24 Night.

Both formulations suppress appetite and help you to burn extra fat but they are very different. The daytime formula gives you extra energy and fights fatigue. The nighttime version calms your mind and helps you to sleep.

This unique 2-bottle system allows Phen24 to help you to remain hunger-free and burn extra fat 24 hours a day.

Visit the Phen24 website

Reasons to Choose Phen24

Phen24 is a good choice for anyone who has had bad experiences with Phentermine and for everyone who needs a diet pill to help them to lose weight.

It will be especially appropriate if you normally have difficulty sleeping or are prone to midnight hunger pangs.

If you choose Phen24, these are the kind of benefits you can expect:

  • Help with hunger (night and day)
  • Faster metabolism
  • Better immune function
  • Feeling more energetic throughout the day and calmer at night

Phen24 also aids collagen formation and provides ingredients that support improvements to your nails, skin, and hair. 

Key Ingredients

Phen24 Day controls your hunger by providing L-Phenylalanine. (amino acid) and Cayenne pepper extract. It also has some guarana to boost your energy levels and help keep you mentally sharp.

There’s some Iodine as well because your body uses this important mineral to produce hormones that influence metabolism. Zinc is a more surprising inclusion but it boosts immune function so nothing to complain about there.

Phen24 night provides glucomannan. It’s one of the most respected natural appetite suppressants in the world so you won’t need to worry about waking up hungry and raiding the fridge. It also provides hops extract to help you to nod off and green tea to make you burn extra fat while you sleep.

  • Have to buy online from the Phen24 website
  • The daytime formula contains caffeine


PhenGold is a good replacement for Phentermine that you may find especially interesting if you have difficulty remembering to take pills.

You only need to take it once per day so, if you get into the habit of taking it first thing in the morning, losing weight should be a piece of cake.

Like all the best substitutes, PhenGold is a multi-action diet pill that combines appetite suppression with other benefits. It places a particularly strong focus on boosting your energy levels and mental focus throughout the day.

Visit the PhenGold website

Reasons to Choose PhenGold

The formulation’s energy-boosting capabilities are partly due to caffeine, but it doesn’t have to go it alone. It has three B vitamins to help it along. B Vitamins help you to extract it from food.

In addition to this, they also aid red blood cell production to make sure your brain and other major organs get a good supply of oxygen.

Phentermine OTC Summary

Although a lot of people believe Phentermine is the best diet pill to take to lose weight, there are better supplements to lose weight. PhenQ, Phen24, and PhenGold are particularly good and all three products come from reputable companies that provide their customers with money-back guarantees.

In addition to being highly effective for weight loss, our top-three OTC Phentermine pills are designed to be gentle on the body. They use only natural ingredients that subdue hunger, accelerate fat burning, and provide other desirable benefits without side effects.

Using Phentermine may be a good way to control hunger, but it’s not the only way. Natural weight loss capsules can do it too and offer additional weight loss benefits as well. They do this without the need for a prescription and you can continue using them for as long as you need.

If your doctor has already offered you a prescription and you are worried about side effects, talk to them about using a natural substitute. 

If you are not obese enough to get a prescription, don’t lose heart. See it as a blessing in disguise and try one of our recommended Phentermine alternatives instead.



Do Phentermine alternatives contain Phentermine?

No, they contain natural ingredients but work in a similar way. They both suppress appetite which reduces calorie consumption.

Is Adipex the same as Phentermine?

Adipex and Adipex-P are brand names that contains Phentermine, so yes, they are the same.
