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.

Great product. For mucas, sinus %26 cough without tylenol, so you're not treating fever too soon and of course because acetaminophen decreases glutathione which helps your body clear toxins, including viruses %26 bacteria! So it's a bad idea when your sick. This product lets you separate these things allowing you to add ibuprofen or aspirin if needed.

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!
