Beware of Counterfeits

Recognizing Fraudulent Brands

A person is holding a piece of green and green tape.

They look like the real deal. The product name rings a bell. The logo of a well-known pharmaceutical company is printed prominently on the label. However, appearances can be deceiving. Find out how you can recognize fake drugs.

They look like the real deal. The product name rings a bell. The logo of a well-known pharmaceutical company is visibly printed on the label. However, appearances are deceiving. In reality, these packages are often manufactured by criminal organizations that want to make a profit at the expense of the patients’ health. They create fraudulent brands to make their fake drugs look like real ones. Neither the quality nor efficacy of these supposed medicines is guaranteed.


Example: Weight Loss Products


Bayer Logo being used to promote non-Bayer medicines.

Bayer has become aware of recent scams involving the use of its name and trademark. In these incidents, advertisements being distributed via social media and unverified websites, claim that Bayer has launched new over the counter (OTC) products including, to-date; a weight management supplement and product for people with type 2 diabetes mellitus. Examples of these advertisements are provided below.

Please be aware that these are not Bayer products and Bayer is not responsible for the distribution of this advertising. Patient safety is Bayer's top priority, and this activity is a way in which criminals can make a financial gain by using Bayer’s name and reputation as well as our high valued Bayer cross to try and make their products appear genuine. Furthermore, such products may cause health problems if taken or provide misleading or false indications of an individual health condition with obvious potential negative consequences.

Please find some photos of the detected misleading advertisement attached. These are just examples not being genuine Bayer products, and the general issue is not limited to the displayed ones while many similar ones are supposed to pop-up.

Example: Testosterone Products


For certain medical conditions, such as impotence or bone loss, patients benefit from a therapy with testosterone. Bodybuilders use testosterone as a doping agent to accelerate muscle growth and to boost their performance (so-called “anabolic agents”). Because users seldom have a prescription, they buy the product through dubious channels. This is extremely risky. “Medicines” that are available from illegal pharmacies or in the darknet are rarely tested or licensed. Bayer has observed that not only fake versions of their products are being sold, but increasingly, “bogus” medicines are being offered that have never been produced by the company, or any other real pharmaceutical manufacturer. Taking testosterone incorrectly can lead to serious side effects. These range from cardiovascular disease to liver cancer.




How Do I Protect Myself from Counterfeit Drugs?

If you are not familiar with a medicine, play it safe. Make sure the drug is actually manufactured by the company named on the label. A quick search on can provide a first clue on whether to trust this medicine or not. You can also ask the manufacturer whether it produces this medication.

Be wary if acquaintances, whether online or in person, recommend certain medicines, or offer to sell these to you. Certain drugs are not available over the counter for a reason. Buying such medications on your own could make you liable to penalties, and taking such drugs could potentially cause serious health damage.


How Do I Recognize Fake Medications?

Real medicines must go through strict control processes. Before they are approved, manufacturers must prove the product’s efficacy in several studies. Of course, scammers using brand names or company logos fraudulently do not adhere to these procedures. Be especially careful of the following:


  • Low prices
    Fake brands or bogus medicines do not undergo development or tests lasting several years. Scammers sell their products for prices that seem too good to be true, and usually focus on this aspect in their advertisements.
  • Fake Bayer cross
    Be wary of products that depict the Bayer cross in a distorted form or with unusual color patterns. Compare the labels with Bayer products that you know.
  • Familiar-sounding product names
    Some scammers invent names for their products that closely resemble the products you know and trust. By entering these names in a search engine, you will quickly find out whether a manufacturer actually makes the drug!
  • Herbal extracts that are supposedly free from side effects
    Natural ingredients can also cause side effects. If a manufacturer claims that their product is especially safe and potent, it is probably a “bogus” product. Worst case, it contains a dangerous cocktail of active agents.
