  • Fenphedrine is an OTC dietary supplement designed for weight loss

  • Claims to work to increase fat burning, build lean muscle, and dramatically reduce appetite

  • Non-prescription alternative to Phentermine

  • Declares itself to be an “advanced weight loss formula.
  • According to the official product page, Fenphedrine was created to inhibit neuropeptide Y (NPY) and stimulate Cocaine Amphetamine Regulatory Transcript (CART) to help aid with weight loss. 

    The Power of CART Over NPY

    The official product page says that CART aids in:

    • Boosting metabolism
    • Reducing appetite
    • Increasing insulin levels

    All this supposedly results in less storing of fat and calories and provides muscles with the energy they actually require.

    That being said, NPY is a stress hormone that:

    • Lowers body temperature
    • Boosts appetite
    • Hinders metabolism

    According to the site, the continual battle between CART and NPY is the reason why a person is overweight. That being said, they offer no science to back this up. 

    Fenphedrine Ingredients are a Mystery

    The only ingredients listed in the Fenphedrine formula include:

    • DiCaffeine Malate
    • Razberi K
    • Thermodiamine

    No other ingredients are provided, and no supplements facts sheet is available for viewing on the official page, which is quite disappointing, as it makes it difficult to learn more about the product other than what the manufacturer wants to reveal.

    This immediately raises a red flag because it makes it seem as though the manufacturer doesn’t care enough about its product to provide the necessary information that allows potential customers to inform themselves. It also makes it seem as though the manufacturer has something to hide, which is never a good impression to leave.

    Furthermore, while the site does provide a few details about the benefits of the three ingredients that it does list, no studies have been provided to backup claims that have been made about them.

    Therefore, while these ingredients may help to stimulate thermogenesis, encourage mental alertness and focus, boost energy levels, burn fat, and lower fat absorption, as the site claims, there is no proof that this is true, which is another red flag.

    It is one thing to say that a product contains clinically researched ingredients and to talk about certain benefits that may help support a person’s weight loss efforts, but it is entirely another to make bold claims about the ingredients without backing up these claims with scientific fact.   

    There is No Guarantee that this Product is Safe

    In addition to there being no substantial evidence that Fenphedrine is effective, there is also no guarantee that it is safe. This product has a high stimulant content, which may increase the risk of certain adverse effects, such as:

    • Insomnia
    • Jitters
    • Headaches
    • Nervousness
    • Anxiety
    • Digestive upset

    The risk of these adverse effects is increased in some people with sensitivities to stimulants or those who might ingest other foods or beverages containing stimulants like caffeine, while taking this product.

    It would be in your best interest to first speak with your doctor before taking this product to make sure that it is safe for you and that it is beneficial to your weight loss goals. This is especially important if you are currently taking other medications or supplements or if you have an existing medical condition. After all, the last thing you want is for this diet pill product to make a medical condition worse or negatively interact with other medications or supplements that you may be taking.

    With that said, when this Fenphedrine review was written, a one month supply (60 capsules) cost $69.95. It also came with a 90-day money-back guarantee.

    October 2019 Update – Fenphedrine is no longer available nor is the official webpage that was dedicated to it currently active. Although you may have hoped to have tried this product, considering the lack of information about it when it was available, it’s not too surprising that it was discontinued and pulled from the digital shelves. It would be far better for you to choose an OTC diet pill that is manufactured by a reputable company that provides detailed information about their product as well as one that cites clinical research pertaining to the ingredients that have been chosen for the formula. You deserve no less than the best.
