I just want to know if anyone has taken Azithromycin (Z Pack) 5 day dosage summing up to 1.5g to treat Chlamydia, Gonorrhea, and Syphilis? 1st day is 500mg and from 2nd day to 5th day is 250mg. If you have tried this, was it successful? From what I understand most dosages are 1g in one dose to cure at least Chlamydia.
