Review of Happy Mammoth


Rated 2 out of 5 stars

Unfortunately did not work for me

I got the gut repair product, unfortunately it did not work for me, instead, it had the opposite effect. I was retaining a lot of water and had digestive issues. I kept a food log and as per refund policy, requested a refund. The bot on the website is unhelpful and never passes you on to a live agent. I have emailed support staff multiple times, never had a response. So the money back guarantee doesn't seem to exist, just like their support staff. Product might work for others, but for me, nada and i was down 60 bucks with no refund in sight. Would not be inclined to buy anymore product again. This does not mean that it doesnt work on anyone, just means it doesnt work on everyone.

Plus point is that the delivery time was as promised. Hence 1 star.

In terms of taste, when mixed with Almond milk or water, its horrendous. I tried it with milk which makes it much more palatable. Almost like a milkshake and it doesn't taste too bad. You taste the hint of vanilla and I could get used to it. That's the 2nd star.

Quantity wise, at 1 scoop, 2 times a day, the tub lasts around 2-3 weeks, and at 50 euros a pop, that can be quite expensive.

3rd star would have been if customer service was responsive. Unfortunately via email, not so much.

4th and 5th star would be if it worked, for me, unfortunately it didnt..for others, maybe it does.

Edit : Received a refund within 2-3 hours after writing this review (minus the shipping fee). I am ok with that. Shame it takes a bad review to get the ball rolling. Thanks HM
