Not sure if this has been answered as I haven’t had the opportunity to read lately, but I believe I have the answer or something along those lines. I don’t believe it is just 2 350mg shots. The 350mg is amount of active ingredient, I believe. The 700mg single dose is likely a higher volume than 350 and 525mg, and a higher concentration of the actual drug, which is what calls for the study. Not positive but close
