ive heard of med-tech but i have not used any of their gear, so cant help you with them. but i would contact the lab(if they have a website) and send them pics of what you have, also if the label has any codes, upics, etc on them i am sure that may be helpful to them. just because they look like another tab doesnt mean that it is, some labs use all the same color tabs. but there isnt any way to tell if they are real just by looking at them. scam artists will go to extreme lengths to make shit look like the originals
