PCOS girly who found perfection!
I have had PCOS my entire life and was only diagnosed in my early 20s and I have followed a very, very strict regiment of diet fitness, low carbs and all of the things and suddenly in my early 30s. I found that my body slowed down and stopped working the way that it was before and the same formula was not doing everything I needed to so I decided to tap into my hormonal balance, and instead of taking a quick one step save Saul pill. I decided to try happy mammoth, and after a few trial and error errors, I went to happy mammoth at hormone harmony plus and weight in the ultimate weight control, combined with my regular regiment of body movement Pilates and daily walking and a strict diet of just whole and fresh foods 98% of the time I could not be happier I am falling in love with my body every single day all over again, and this is a huge part of that so things to consistency, patience, and a healthy diet and I have metabolism and everything seems to be working in my favor so if you might be in my shoes and you’re looking to reclaim what was lost, I highly recommend this product. Just know that you have to be patient and you have to follow a regiment of healthy Whole Foods and just have fun with it embrace it and enjoy the journey!

Bait and switch
Bait and switch. Bought 4 jars for $201.60. The guarantee was for 60 days. Product did not work. I gained weight. So I wanted a refund. They said they would only refund just the one bottle.

Bought Complete Belly Reset in 2025
Bought Complete Belly Reset in 2025, worked unbelievably well but they seem to have changed the formula in 2026 and its no where near as good this time. The old version would mix without clumping but this new version is almost impossible to stop it sticking together and become lumpy. The old version also lasted much longer too, the spoon was half the size of what it is now. Not sure ill buy it again unfortunately as im not getting the same results anymore

Hi Juan,
Thank you for sharing your feedback, we appreciate you taking the time to explain your experience.
We’re sorry to hear that the product hasn’t met your expectations this time. There haven’t been any changes to the formulation, but we understand how differences in texture, scoop size, or overall experience can feel noticeable.
If you’re finding it difficult to mix, you might try adding the powder gradually while stirring or blending, which can help reduce clumping.
We’d be happy to take a closer look at your experience as well. Please feel free to reach out to us at reviews@happymammoth.co with your order details so we can assist you further. And if the product doesn’t feel like the right fit, our 60 day money back guarantee is there for you.
Warm regards,
Happy Mammoth.

Good products to help with hormones and mood
Good products to help with hormones and mood. Like the collagen powder vanilla and salted caramel go well together with my morning matcha, delicious. Bit on the pricey side and having to take 4 tablets a day seems a bit excessive maybe they could make the tablets more potent so you can take less?? Service is good and speedy delivery. Customer service is also good and they respond fast to queries.
