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 for cough, not for nervous disordered people

Not great for people with disautonomia, nervous disorders or heart issues. It will speed you up, and you may see things even on a low dose if you have neural issues.

This stuff works. Need I say more? Cleared up the mucus. Decongestant was a blessing. And at the end of the day when I needed to sleep it quieted my cough so long as I took it all day long.
