There has been a shipment delay so I haven’t actually received it yet, but dealing with the company was good

I was very happy with the results after I adjusted to a dose that worked for my application, and plan to reorder the product.

They were very helpful and timely. Only issue I had was I didn’t get my bacterial water so I had to send an email and then they sent it out asap and sent me 10 ml vial until they could get me the 30 ml vial I paid for.
