While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

WARNING – FAKE WEBSITE AND COUNTERFEIT PRODUCTS!

Happy Mammoth USA is a complete clone of the genuine Happy Mammoth website. The product I received in the post was clearly a copy of the original, not a genuine Happy Mammoth product. I have since thrown it in the bin, contacted my bank and demanded a refund from Happy Mammoth USA, which they have issued after acknowledging that the product was not genuine.

The website is extremely misleading and designed to look like the genuine brand. Please be warned and do not buy from this website. Check carefully before handing over your money!

Make sure you when you buying Happy Mammoth products like Hormone Harmony that you are on the genuine site which does not have “usa” at the end of your link.
