Before you spend money on that “Shark-approved” miracle invention, weight loss product, or keto diet pill, are you sure it’s really been through the Tank? Really sure? Scammers are using fake Shark Tank celebrity testimonials and endorsements — complete with doctored photos and videos — to generate buzz and profits. Before you click and buy, follow this advice and check it out.

Here’s what to do if you’re wondering whether something is Shark-approved:

  • Approach celebrity testimonials with caution. Look for product reviews on your own. Search the product online and put words like “scam” or “problems” or “complaints” to see what others are saying about the products.
  • Go directly to the source. Don’t click on a link or ad. Instead, check out a full list of all businesses that have been on the show at
  • Remember: the government doesn’t review or evaluate supplements for safety or effectiveness before they’re put on the market. Your health care professional is the most important person to ask whether a supplement is safe for you. Even a natural supplement can be risky depending on your health and the medicine you take.

As I recall, some of these ads show pictures of celebrities and quote them. Never mind that the celebrity never made the quote, isn't it illegal to use someone's picture commercially without their consent?

If these celebrities are not getting a financial kick back, why haven't they sued these companies?

I can't understand why this is legal! It seems to be just as bad as a Nigerian prince scam or an Indian Microsoft scam. What is the difference? It seems to me that this is a perfect example of false advertising, misleading information, and very manipulate. Weight loss is such a touchy subject for people. It's awful.

There has been a steady steam of weight loss ads on the net. By answering one and whether or not you purchase , it opens the flood gates with similar offers

Last night I found a link to Keto Weight loss endorsed by Shark Tank from a Facebook friend. The advertisement quoted $39.99. When they billed me it was $199 and another for $59. I tried to cancel right after purchase and was told since I disputed that I couldn't cancel and to wait until delivery. I told them I wanted it canceled and then waited. I'm hoping the transaction cancelled. The 59.99 charge was compulsory to get through the original purchase of $39 which ended up being 199. Put a stop to this company please. I saw the same 5 bottles advertised online afterwards for $89.99.

I had the same issue. 199 out of right field. I canceled and the firm/scammers kept sending the product. Doesn't work.
