Thanks for your revisions. Could we see #11 with a more techno looking font for the "Certi" portion and in gray/blue or some other color combination you might suggest?
Might be interesting to see against something suggestive of a tablet or capsule.
#48 has what I am looking for with the suggestion of a tablet. Also, the "x" is more of a subscript to the "R," which is how "RX usually is representated when it is used for prescriptions. Could you do anything more like that,, and show th gap you have above on the short stroke of the x on the bottom too?
