eerrrrpp. you may just want to stick a little note/comment or something that these are intact "ESTERS"not amide. Amides (have TWO "i'"'s in their name while esters have ONE.. there is significant difference in clinical application. for example: don't give an Amide to a super young or old or cirrhosis or liver fail patient. and ESTERS have a higher incidence of allergic reactions i believe? Yes? anyway good work though-dont mean to "nit pick" at cha cuz i would make a million mistakes on one of these vids as well ha -peace
