[ziad adore my father]

Today i went to buy for dad the neupogen injection, it seems that nobody have stock due to a shortage from the dealer, i called our local doctor to ask about substitute he ask me to buy Neutromax, i called the our other doctore he told me No, bring Zarzio !! Qhat is the difference and which one is better? Or which one has the better result? Should i wait till i find Neupagen??
