I’ve been using the products for over a year now. Love the complete gut repair system. The powder mixes perfectly into my daily lunch time smoothie. The customer service is spot on if you ever have any issues. Highly recommend Happy Mammoth!

I’ve been using Hormone Harmony for 6 months and I noticed right away it positively changed how I felt in terms of fatigue, muscle soreness etc. Later I noticed a decrease in brain fog. I didn’t realize how strong the effects were until I stopped taking it for about 5 days and felt awful. I had forgotten I used to feel like that all the time. My GYN and I discussed and I’m staying on it while we add progesterone for some HRT as well and so far it’s a great combination. It hasn’t really affected weight but the other benefits feel worth it. If I could only get my HSA to cover it.

I bought 2 months of Hormone Harmony following their online quiz. I got a bit of a Black Friday deal and thought I would go for it. I paid far more than I usually would for this kind of supplement (£97), but bolstered by the money back guarantee I thought I would give it a go. You have to take 3 tablets each day and there are 72 in a tub, so not even a month's supply for the price, which I considered as a red flag when they arrived! I took the supplement every morning for 2 months and have felt nothing. No change, no weight loss. I'm so disappointed. When contacting the customer support bot I'm told that depending on your body it can take time for it to work. Considering the high price, I'm not going to gamble to continue my use of this product with a return of nothing. I've also been refused my money back at I'm outside of the 60 day window. Even though I bought these during a Black Friday sale and started them in January. I thought it would be pointless taking them while my diet/routines were out over Christmas. Wasted money!

I have been seeing the Complete Gut Repair ad popup for a couple of weeks so I finally decided to try it. I click on the link do the quick pay and done. The product arrives a few days later, I open the box and its not what I thought I was ordering from the ad. So I go to the support tell them what happened, I don't want this product, I'll return it. They give me the shipping information, ask me to send them my shipping tacking number after I ship it and that it will take up to 14 days after they receive it to process.
Wait, so its going to take several weeks before your company can send out my order?
The support person says, if you want it faster you can place another order and we'll get it right out to you.
Grrrrr
Why would I order more products from a company that can't resolve my original order in a timely manor?
I asked for a phone number and they don't have a public facing number? So I'm stuck with emailing support, and I know support wont escalate my ticket to the bosses.
From the time I arrive home at 2:30, opened the box, talked to support, went to the post office to ship the return, and emailed support with the tracking information. Their product was in my hands for about 90 minutes. But I have to wait 3 weeks.
On top of that, I had to pay $15 to return the product, they didn't even consider sending me a return label...
So far I have received nothing but grief for the time and money I have spent dealing with this "Happy" company.

I've been in Hospitality industry my entire life, if I treated my guest like this, I know they'd never return.

Very Disappointed!

At first I was like this isn't doing anything.
Then I hadn't taken the tablets for a few days and I got my period. I have really painful periods where the entire first day is excruciating. About lunch time I was in heaps of pain and I decided to take a dose of Happy mammoth.
Pain gone within 15 minutes!!!!!! Omg the best thing ever.
I didn't know if would help but it seriously did. 🤯

Notable reduction in hot flushes after two weeks

I believe it has begun to reduce my hot flushes, both in how often they occur and their intensity. I've only been using it for two weeks, but I plan to keep using it to see if I experience any further improvements.

High cost but effective for my well-being

Despite the high price, this product has truly benefited me. I've regained my energy, my mood feels improved, and I find it easier to cope with a difficult relationship.
