I have been searching the internet for a cheap source of immunovir for years and years lol. Usually when i find a cheap source its too good to be true and or shipping is dam expensive. Anyway i have found a source that is the cheapest i have seen although i dont have a shipping price yet, waiting to hear back from them on that. The price on their web page is $43.44 for 50 x 500mg tabs. Comparing that price to equivalent 200 tabs from another common site selling immunovir is $100 cheaper. I would appreciate hearing from anyone who has used this company. Also hope that others who have been looking for isoprinosine/immunovir find this link helpful. http://brandmedicines.com/index.php?main_page=product_info&cPath=24&products_id=746 cheers!!!
