Great product
Great product, have been taking for some time now and clearly helping to keep estrogen under control in a natural way. I’ve had bloods done which show my Oestradiol is in normal range. Highly recommend you try.

Increased energy and not feeling tired
I have been taking for a couple of months and appears to be having a positive impact as I definetly feel that I have more energy and do not feel as tired. I have not noticed any side effects from taking the supplement.

Feel a massive difference taking with boron, tongkat Ali and taurine. Never felt so good all through the day.

If in doubt give it a go.
I am just about to place my fourth order. I am 58 and either run or visit the gym every day. I have increased energy and motivation but am not sure if the tablets help maintain my drive or a recent increase in cardio training is making feel more energised and shifting stubborn middle aged fat. For context, I have trained on and off for most of my adult life and not feeling any need to slow down. If in doubt, give it a go.

Would high recommend!!
This is the second bottle I’ve brought. I have noticed a lot of difference in my belly I don’t get no where near as bloated, slight change in my chest but it does state it takes 3 months to see proper results so as of now I’m happy with how it’s coming along. I’ve also noticed my libido is higher and I’m not having trouble with erections anymore having them a lot more than I’ve had in years, firmer and stay. Given me my confidence back in the bedroom that’s for sure.
