Yeah, probably 3mg (for 0.3, 0.6, and 1mg doses) and 12mg (for 3mg, 4.5, and 6mg doses). And once these clinical trials report their results, or once enough Meso members figure out what range seems to work, maybe you'll only need one size.
I think I read somewhere that 12mg doses universally caused vomiting. But I may be getting that confused with a long-acting “semaglutide” candidate that had similar dose ranges.
Also note that 0.3mg looks mildly efficacious. I think highest approved dose will either be 4.5 or 6mg (maybe 3mg, much lower chance). Positive Cardiovascular effects seem to really kick in around 3mg.
