Breaks Up Congestion

I have asthma and another lung condition where my lungs hold mucus. This helps break it up so you can cough it up.

Good stuff!

Very good. Does not leave a dry mouth. Reduces cough and raspy voice.

Just what I need!

I take mucinex for the 100% guenisen. I take it as part of the guefenison protocol for fibromyalgia myalgia. It is affordable and it works!

Major cost savings

Medication is almost half the cost of the name brand medication and works just as well.
