Upper Respiratory Tract Infection
"Amazing for chest infection. I had been tight and congested with fatigue and aches. Within a day of first dose the phlegm started to break up allowing me to cough the mucus out of my lungs. I feel so much better!  It doesn&rsquo;t always work due to virus/bacteria thing but I can usually tell the difference by how I feel and this time I was right. Zpack was needed and fixed me. No terrible side effects for me."
