Magic tablets

I’m honestly so surprised how much these tablets changed my life. I’ve struggled with weight loss being in my 40’s but within a week I felt lighter, more energetic and less bloating. I’ve run out and can’t wait to get the next supply. Highly recommended - magic tablets

Using Hormone Harmony and Hormone…

Using Hormone Harmony and Hormone Harmony Plus.
Because I'm an idiot, I buggered up my order but the support team were terrific and set me right! I've been using now for almost 3 weeks:
1 - have been sleeping better
2 - have not needed to use an ibuprofen
Haven't noticed any physical looking difference, but you know, early days (will be checking out other Happy Mammoth products.

I've been taking Hormone Harmony for over a week now and I'm already noticing some benefits. I feel less bloated and have less stomach discomfort after meals. I also feel calmer overall and in a better mood.

Feeling Calmer and More Balanced

I feel much calmer and more emotionally balanced since I started taking this supplement. It has really made a difference in my daily life. I honestly feel anxious without it now. I will definitely be purchasing it again.

Very bad customer service.

I’ve been taking hormone harmony a while now. Did nothing for weight as they are so proudly advertise but I have to say that some of my horrible joint pains got easier. Decided to order gut repair. The delay was unbelievable. Finally when arrived the packaging came destroyed. The customer service was so unhelpful. Finally they offered to resend only the 2 out of 4 destroyed jars. And guess what. The package was lost. And customer service once more was very unhelpful. Dont know when and if ever i will receive the jars. But for the amount you pay it really is jot worth all this trouble. Also if something is going to work you need to take it properly. Not with 2-3 months gap because of bad service. Not sure im doing this again!

With the protein powder

With the protein powder, I have been able to eliminate my breakfast and urges to eat and snack for most of the day. Resulting in about a 10 pound weight loss. I will continue on the same program as the rest of my day meals have not changed. This has been very easy and seeing results is an absolute bonus.

Wrong Product, Bad Customer Support Structure.

Update, someone from the company has reached out and she is making a great effort on behalf of the company to make things right. The company is send product my way, I'll update my review once I've had the chance to try the product for a few weeks.
Thank you to Brenda for her efforts to restore faith.
PK

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!

Happy Hormony Harmony

I wanted to take something for the constant bloating I had as it seemed as though I would never get rid of it. I came across Hormone Harmony and thought I would give it a go. Now I notice that I am also calmer, less anxiety though I do feel anxious sometimes. The full bloated feeling during the day is definitely gone and to boot I am actually also loosing some weight which is good. I am glad I am taking these tablets. One a day for me works wonders. Will definitely get another bottle when I need more
