Good Stuff

I had Covid and I was unable to get medication for it. So I ordered this and I have to say that it did a pretty good job. I was so congested and had bad aches and pains in my muscles. This really helped with the aches in my muscles and the congestion. I would highly recommend it.

Huge surprise in a small bottle

I purchased this after awful ,mood wrecking congestion. I fought through a week or so of sleepless nights because I didn't want any thing that tasted awful or made my body feel “odd”. I found this and remembered the ads😊 This worked from the first dose and throughout each dose after. My mood also lifted. I was shocked at the amount of mucus that came out! It was truly a cleansing. I now keep a bottle on hand ALWAYS ⭐️

This medication definitely works like magic! Highly recommend for congestion!!! I read all the reviews first, and they were right on the money! Can't recommend more! Absolutely 💯 works! It does taste like strong medicine, but to me, as long as it works, I don't care what it tastes like!
