Seemed like an okay product but nearly impossible to cancel your subscription.

After 20 days consistently using the product exactly as prescribed, I asked for a refund, as the product did nothing to help my gut situation or bm situation!
They won't respond. that STINKS. No phone number, just an email and an AI response one time saying I was outside the 30 day time period for returns, which I am NOT!

This company takes your money but does not deliver the product. Avoid using.
Update; they did provide a refund after a number of emails.
