8 months and we felt no difference.
We took Qualia Senolytic once each month, for two days in a row, as recommended. We did this for 8 months in a row. Each month, we felt zero difference. We are pretty healthy, in our late 50's/early 60's. We did not feel any better, nor any worse. So we have canceled the subscription. Also, please allow folks to sort your reviews by 'star' level on this website. I sort reviews by star level, and read the 1 and 2 star reviews, before also reading 3, 4 and 5 star reviews. You can't sell a product through deceptive practices for long. People aren't stupid, and they're not going to waste their money on something that has no discernible effect. Trust me I wanted this to work or help, but we noticed no difference at all.
