I appreciated knowing he would be the surgeon for the procedure scheduled in short orderAnd is was just shy of miraculous that he was able to get sample blood thinner meds to cover the time It takes to recieve them from Cost pulse pharmacy . It was also hugely appreciated that this clinic with both last providers established getting me set with Mark Cuban pharmacy given medication was financially unfeasible under regular route pharmacy.Being told it was necessary to prevent stroke risk between now and procedure and was out of reach economically it was quite actually a potential life saver
