oh man do i empathize...well,your source suggested a blood test and all will be well after that...jeez,he knows you're out some money and knows that it costs money for a blood test,so there's your catch 22...sounds fishy to me...usually,a good source will back his product(s) 100% and will accept his product back...he should not be hesiatting and asking for u to pay for the blood test...if he really wants that,then ask him to pay for half since HIS product(s) are being questioned...fyi
