Great product
Great product. Had been using it for a month, ordered more and then found it was out of stock. Very annoying and poor communication from the company in the delay.

I’m currently on my third bottle of Happy Hormone Plus, and I wanted to share my experience for anyone else going through perimenopause.
I’m 47 and started having symptoms that didn’t feel “typical” — I had this constant pressure in my chest that felt like anxiety, unexplained weight gain in my midsection, poor sleep, and overall just didn’t feel like myself. It was frustrating and honestly a little scary at times.
After doing some research and speaking with my gynecologist, I decided to give this supplement a try while also moving forward with bloodwork and hormone testing.
Now going into month three, I can say I’ve noticed a real change. The chest pressure I was experiencing has drastically subsided, which has been such a relief. I’m also starting to sleep better at night, and that alone has made a big difference in how I feel day to day.
As for weight, I’ve only lost a few pounds so far, but I can tell my belly is starting to soften again, which gives me hope that things are moving in the right direction.
Overall, I feel more balanced and more like myself again. It hasn’t been an overnight fix, but the steady improvement has been encouraging and worth it.
If you’re dealing with similar symptoms, I’d definitely recommend talking to your doctor and considering this as part of your plan. It’s been a helpful support for me during this transition.

Total Scam!
I am giving zero stars. This product provided hope thru the adds, a promise of 60 days to try the product or get your money back, then a deal to purchase more bottles so that you get a deal! Don't fall for it! It did not work for me at all! I followed instructions to do a return within the 60 days, sending pics of the bottle and boxes for both of my bottles, one new and other 3/4 full. I purchased tracking, the happy mammoth agent said it was necessary. Jumped through every hoop and then told they are only refunding one bottle. Somehow in my purchasing I should see that with the 60 day money back guarantee, IT ONLY COVERS ONE BOTTLE!
when I explain this to the agents sending me emails, no one wants to work with me on getting the rest of my refund. This is not what I needed on top of the symptoms I am experiencing that this product promises to help. ..... or your money back. Don't purchase this product! Customer Service is horrible!

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.
