Potential Benefits of Taking this Dietary Supplement

Before listing the possible benefits associated with taking this dietary supplement, it is important to point out that although PhenObestin 37.5 is marketed as a non-prescription phentermine alternative, the reality is that it is not truly an alternative. Currently, there are no over the counter (OTC) weight loss pills that have been approved as a prescription-free alternative to phentermine and related diet drugs that have been FDA-approved to treat obesity.

Regarding the claims of PhenObestin’s benefits, they are as follows:

  • Appetite suppression
  • Hunger control
  • Fat burning
  • Enhanced mood
  • Improved blood circulation
  • Sustained energy

PhenObestin 37.5 Ingredients List

When this PhenObestin 37.5 review was written, the white with blue spec tablet contained:

  • Phenylethylamine HCl
  • Thobromine Anhydrous
  • Yohimbine HCl 99%
  • Methylsynephrine HCl
  • N-Methyl-B-Phenylethylamine HCL
  • Synephrine HCL, and Caffeine Anhydrous

As you may have noticed based on the above list of ingredients, PhenObestin 37.5 contains only stimulants. As such, it is not out of the realm of possibilities that it will increase mental alertness and boost metabolism levels, which could help prevent fatigue and assist a user in getting the most out of there workouts.

For instance, there have been clinical studies that have suggested that caffeine can help stimulate metabolic rate and lead to greater oxidation of fat.

That said, there is no clinical evidence that proves taking PhenObesting 37.5 will lead to weight loss, with aid in long-term weight management efforts or that it is safe to take.

Stimulant Overload

What is alarming about the above list of ingredients is the fact that every single one of them is a stimulant. This automatically raises a lot of red flags and calls the safety of this product into question. The simple reason being, multiple stimulants increases the potential occurrence of adverse side effects, especially for individuals with certain medical conditions, individuals who may be taking certain medications, and for anyone who has sensitivity to stimulants.

Some common side effects associated with stimulants include, but are not necessarily limited to:

  • Rapid heartbeat
  • Jitters
  • Sleeplessness
  • Anxiety
  • Headache
  • Stomach upset
  • Mood changes
  • High blood pressure

Considering PhenObestin 37.5 contains so many stimulant ingredients, this diet pill may not be the best choice for individuals who are sensitive to stimulants as the risk of potential unwanted side effects may outweigh any possible benefits. Since this is the case, it would be wise for these individuals to avoid this product altogether.

Also, keep in mind if this is an OTC weight management aid that interests you, and you do not have a problem with stimulants, it would still be in your best interest to avoid ingesting other stimulant products (e.g. cola, coffee, caffeinated tea, energy drinks, etc.) while taking it to reduce the risk of adverse effects.

Finally, if you have been diagnosed or are being treated for a medical condition or you are pregnant, nursing a baby or planning on becoming pregnant, you should first speak with your healthcare provider before taking PhenObestin 37.5. Never make the assumption that a dietary supplement isn’t dangerous simply because it can be purchased without a doctor’s approval or because a manufacturer claims the formula is safe.

Update – January 2020: PhenObestin 37.5 has likely been discontinued. The product is no longer sold online by the manufacturer or on Amazon. Although it isn’t available for purchase, if you were hoping to find a non-prescription diet pill that offers support with mental alertness, energy enhancement, metabolism boosting, and hunger control, there are other OTC weight management aids that you can investigate and try.  


Obilean is a dietary supplement for weight loss from Feel Spirit Supplements. It’s a non-prescription product that has been designed to appeal to individuals seeking an over-the-counter (OTC) alternative to prescription diet drugs like phentermine. The tablets are even white with blue specks to mirror the look of phentermine.

The maximum strength pharmaceutical grade formula has been developed for the purpose of reducing appetite, for acting as a thermogenic fat burning aid, and providing weight management support.

One Obilean tablet makes up a single sized serving and is composed of the following ingredients: Beta Phenylethylamine HCL (375 mg), Caffeine Anhydrous (125 mg), L-Theanine (62.5 mg), Hordenine HCL (15 mg), Theobromine (15 mg), Synephrine (15 mg).

Users are directed to take 1 – 2 tablets in the morning and 1 – 2 more in the afternoon. No more than 4 tablets should be exceeded in a day.

In terms of Obilean’s effectiveness, it is likely that you will receive a boost of energy and mental alertness due to there being multiple stimulants in the formula (ex. caffeine, phenylehtylamine and synephrine). This could be beneficial in terms of helping you to burn more fat, especially when this product is combined with physical activity. That being said, to achieve measurable fat loss when taking this supplement, you still need to engage in regular exercise and eat a calorie conscious diet.

Keep in mind that Obilean is not safe for everyone to take. It should not be used by anyone under the age of 18 or by pregnant or nursing women. If you have sensitivity to caffeine or any other stimulant you should first speak with your healthcare provider before taking this product. In fact, you should speak with your doctor regardless if you have a health condition or not, to make certain that Obilean is an ideal choice for you.

Finally, be advised that consuming caffeine while taking Obilean can be dangerous to your health. This dietary supplement already contains a high dose of caffeine as well as stimulant ingredients that enhance the effects – both good and bad – of caffeine. What this means is that while you are likely to get a significant boost in energy, you’re also at a much higher risk of experiencing adverse effects like jitters, sleeplessness, restlessness, rapid heartbeat, anxiety, headache, gastrointestinal upset, etc.

When this review was created, a bottle of Obilean could be purchased on Amazon for $47.49.


PhenterMaxx is another OTC (over-the-counter ) weight loss supplement created as an alternative to prescription diet medications like Phentermine and Adipex-P. It is manufactured by Ultimate Weight Loss Labs and supposedly works to suppress appetite, super-charge your energy, burn fat without depleting muscle, and provides you with more control over your mood.

The main active ingredient in PhenterMaxx is phenylethylamine HCl. Phenylethylamine (also known as PEA), is a common weight loss ingredient and is often found in many OTC dietary supplements designed as Phentermine alternatives. It is a stimulant that is believed to help increase alertness, improve mood and concentration. It is also commonly believed that it helps to suppress appetite, however, there isn’t enough clinical evidence to back up this claim.

Furthermore, PEA is frequently used in combination with caffeine as it can enhance the effects of caffeine, which may lead to the burning of more fat when combined with physical activity. PhenterMaxx contains 150mg of caffeine anhydrous per serving (1 tablet). In addition to caffeine and PEA this product’s pharmaceutical grade formula also contains N-Methyl-B-Phenylethylamine, Yohimbine HCL, Theobromine Anhydrous and Synephrine.
Based on this ingredients list, it’s clear that the formula contains multiple stimulants, including synephrine, a naturally occurring stimulant in bitter orange (citrus aurantium), which not only enhances the effects of caffeine, but can also lead to more serious adverse effects, such as high blood pressure, heart attack and stroke.

That being said, while such dangerous effects may not be a serious threat for most individuals who follow the directions of this product, it should be noted that there is a risk of experiencing other unpleasant side effects associated with these stimulants, such as jitters, anxiety, insomnia, mood changes, upset stomach, headache, rapid heartbeat, and so on. To help reduce the risks of these effects, it would be wise to avoid taking any other stimulants (ex. drinking coffee, tea, energy drinks, soda, etc.) while using PhenterMaxx.

The recommended directions are to take 1 tablet after breakfast and 1 following lunch. You should not exceed 4 tablets within a 24 hour period. For optimal weight loss results, this product should be combined with a healthy and calorie-conscious diet and regular exercise. Taking PhenterMaxx without making additional conventional weight loss methods is unlikely to lead to any measurable fat loss success.

Presently (when this review was written) PhenterMaxx could be purchased on Amazon for $59.99. Be that as it may, speak to your healthcare provider prior to taking this product.


Phen700 (Phentemine 700) promises “fast and amazing results.” According to the bottle’s label, it is a “Pharmacy grade appetite suppressant dietary supplement.” This diet pill is also supposed to help improve sleep, increase energy and lower aches and pains.

The active ingredients in Phen700 include: Phenylethylamine, Synephrine, Caffeine, Nettle Leaf Extract, Yohimbine Extract, Insoitol Niacinate and Picamilon.

How do these ingredients benefit users of Phen700? The official website of the product says that Phenylehylamine (PEA) improves mood and increases alertness, which can be beneficial for improving exercise performance. Synephrine (bitter orange/citrus aurantium) is a fat burner that works best when combined with caffeine. Caffeine acts as a catalyst in Phen700, enhancing the effects of the other ingredients in the formula. It also raises energy levels and mental awareness.

Nettle leaf helps to reduce water retention, contains many vitamins and minerals and may also help to relieve joint pain. Yohimbine has been found to hinder a mechanism in fat cells that prevent weight loss. Inositol niacinate can help to lower bad (LDL) cholesterol and raise good (HDL) cholesterol when combined with proper exercise and diet. Picamilon assists the other Phen700 ingredients in helping users burn extra calories and prevent fat production.

Although this sounds impressive, the reality of this product is that not a single one of the ingredients it contains has ever been scientifically proven effective for weight loss. Research has shown that stimulants, like caffeine, are fat burners and can improve alertness, but boosting alertness and even fat burning does not guarantee weight loss.

Also, while synephrine does enhance the effects of caffeine, this may cause more harm than good. Not only does it increase the risk of unpleasant side effects like sleeplessness, jitters, rapid heartbeat, anxiety, upset stomach, etc., but the FDA also warns that it can increase the risk of serious cardiovascular effects including heart attack and stroke.

This product contains a diuretic (nettle leaf), which could increase the risk of dehydration and even heat stroke from exercise if not enough water is ingested. Furthermore, Phen700 has picamilon in its formula which is a drug and not actually a dietary supplement. Picamilon has not been approved by the FDA and does not meet the FDA criteria for compounds that are allowed in dietary supplements.

Another aspect worth noting is that according to the official product website, in America, Phen700 has proven in users an average 25 pound weight loss in just six weeks. While quite a bold and eye-catching statement, it would be more impressive if the website actually supplied facts or studies to backup this claim. Although the site does have positive testimonials, testimonials are not enough to prove the safety or efficacy of a product. In short: there is zero proof that users will lose any weight while taking Phen700, let alone 25 pounds in six weeks.

If you are interested in making Phen700 a part of your diet and exercise weight loss program, you are strongly urged to first speak with your doctor before taking this product.

When this review was written, a one month supply of Phen700 cost $67.00.

Phenadrine Slim Sticks

Not all over-the-counter phentermine alternatives come in the form of diet pills. This is the case with Phenadrine Slim Sticks, a weight loss product from Biogen that has been designed as powder to be mixed with water and taken as a beverage. It has been formulated to boost energy, encourage rapid fat loss support, enhance mood and stimulate metabolism and the breakdown of fat.

Phenadrine Slim Sticks contain several ingredients within its proprietary blend. They include: Mango Seed (Irvingia Gabonensis) extract, Green coffee bean extract (45% chlorogenic acid), Caffeine anhydrous, Citrus Aurantium (30% extract), Yerba Mate (25% Xanthins), N-acetyl-l-carnitine. It also contains Inulin (Prebiotic fibre), Flavorants, Citric acid, Malic acid, Non-nutrative sweetener blend (Acesulfame-K, Aspartame [contains Phenylalanine]), Colorant, (E124, E104, E110).

The ingredients within the proprietary blend are believed to help with weight loss. For instance, Mango Seed is said to lower cholesterol levels and improve blood circulation. Green coffee bean supposedly helps to quickly burn fat. Caffeine can increase mental alertness and may increase metabolism. Citrus Aurantium is believed to increase metabolism, energy and calorie expenditure and may act as an appetite suppressant. N-acetyl-l-carnitine is believed to encourage the uptake of fatty acids into your cell mitochondria, so more of your energy comes from burning stored fat. Yerba Mate may help with appetite control.

Unfortunately, aside from caffeine having been clinical proven to increase alertness, none of these ingredients has ever been scientifically proven safe or effective for weight loss. Therefore, while Phenadrine Slim Sticks may give you a boost in mental alertness, there is no guarantee that they will help you lose weight.

In addition, this product contains more than one stimulant. A risk of unpleasant side effects such as insomnia, jitters, anxiety, rapid heartbeat, and other stimulant-related effects is possible with this supplement. Furthermore, be advised that it contains both caffeine and synephrine (a naturally occurring stimulant in citrus aurantium), which can be a dangerous combination as synephrine enhances the effects of caffeine, and this could lead to serious cardiovascular effects including high blood pressure, stroke and heart attack. Anyone interested in taking this product should first speak with their healthcare provider.

The suggested dose for Phenadrine Slim Sticks is to take 3 sachets per day, 1 sachet 30 minutes prior to meals or snacks. A single sachet should be added to 500ml of water. It is recommended for users to take the first dose on an empty stomach in the morning either before breakfast or before a workout. The second dose should be taken before lunch. If users choose to take a third dose, it should be taken prior to 4 pm to avoid sleeping difficulties.

Users are also instructed to take this product 5 days in a row and to stop it for 2 days before beginning again. The manufacturer recommends taking Phenadrine Slim Sticks in conjunction with a healthy diet and regular exercise.

When this review was written, this product was only available for sale in South Africa.

T5 Turbo – Phentramine-RX: Extreme Fat Burner

T5 Turbo – Phentramine-RX: Extreme Fat Burner is a non-prescription weight loss pill from Optimum-FX. It has been designed as a thermogenic formula to suppress appetite and boost metabolism. It is said to be a fast-acting diet pill that can help aid in the reduction of belly fat and provides users with the energy to be more active. This fat burner is claimed to be so strong that it will even help you burn more calories when you are at rest.

At the time this review was written, an official product page for T5 Turbo – Phentramine-RX: Extreme Fat Burner did not exist, but it was still sold online. A single bottle containing 60 capsules sold for £29.99 ($45.00).

The T5 Turbo – Phentramine-RX formula contains the following ingredients: Alpha Lipoic Acid, Caffeine Anhydrous Extract, Citrus Aurantium Whole Fruit, and L-Tyrosine.

Every single one of these ingredients has been clinically researched. Some research suggests that these ingredients may be beneficial for aiding in weight loss. For instance, Alpha lipoic acid may potentially reduce blood sugar levels. Caffeine anhydrous could boost metabolism and the body’s fat oxidation rate. Citrus aurantium (better known as bitter orange) may boost resting metabolic rate and energy expenditure. L-Tyrosine could enhance energy levels and even cause appetite suppression.

Unfortunately, the research that has been conducted on these ingredients has not provided sufficient evidence that proves that any of these ingredients are safe or effective for weight loss. Essentially, there is no proof that this product will help you to lose weight fast or at all.

Furthermore, the T5 Turbo – Phentramine-RX formula has more than one stimulant. In addition to caffeine, it also contains synephrine, which is a naturally occurring stimulant in citrus aurantium. While having multiple stimulants does increase the risk of side effects, such as insomnia, jitters, anxiety, rapid heartbeat, etc., the combination of caffeine and synephrine also increases other more serious risks. This is because Synephrine enhances the effects of caffeine. As a result, the combination of these two ingredients can increase the risk of fainting, increased blood pressure, stroke and heart attack, according to a warning from the FDA.

For first time users of T5 Turbo – Phentramine-RX, the suggested dose is to take 1 capsule 20 minutes before breakfast with a glass of water. Once users have assessed their tolerance, they can continue to take only 1 capsule per day, or they can up their dose to a maximum of two capsules per day and take the second capsule 20 minutes before lunch (also with water) or in the early afternoon. To avoid sleeping difficulties, users are warned not to take a pill any later than 8 hours before bed.

It would be prudent to first speak with your medical practitioner before taking T5 Turbo – Phentramine-RX.
