Sublingual semaglutide/tirzepatide

injection = Ozempic 0.5-2 mg/wk

oral tablets = Rybelsus 3-14 mg/d = 21 - 98 mg/wk

There is no once weekly dosing of the oral. It's daily and way more than subQ.

Some people haven't crossed the line of injecting yet. We were all there once. Not judging.
 
The real question is how expensive is it to synthesize GLP-1s in a standard lab? Take paracetamol. Synthesizing 2,800 mg would e.g., cost a few cents at best - but paracetamol is a rather easy synthesis, and i assume sema is much harder. But perhaps with scale you could do it cheaply. Otherwise, Chinese chemists need to get back to the drawing table and figure out some other GLP-1s with better sublingual bioavailability

Peptides are different than other molecules. It requires multiple steps, with each step elongating the peptide chain. The longer the peptide chain, the longer the required steps. Upscaling production is not simple too.
 
I'm no organic chemist so don't have a sound perspective on sema production. But insuline was also v hard to make initially before it became easier & cheaper & better. Took a couple decades. But perhaps we'll see production techniques progress faster this time around
