I didn’t look at the analysis. In general, I did not feel any obvious changes. This is normal. I’ll drink it for two months and take a break

I have the same. Plus I’m caulking, hemp lightened. In general, there is a result. Configured to drink a confident course in 2-3 months. If the review was helpful to you, please press YES. Thanks!
