retaglutide is the next gen (3rd) GLP-1 which is in phase 3 trials now. It is a triple antagonist (current are dual GLP-1/GIP). It adds glucagon, and apparently that comes with not only greatly increased weightloss, but also wicked sugar cravings.

These things do way way more than just appetite and craving suppression.

Interesting! how does that work though? I thought reduced sugar craving was part of how GLP-1s aid in weight loss as the paitent craves sugar less and thus eats less.

I'm not a biochemist, so I can't say with any authority, but presumably its to do with the 3rd antagonist and its impact on glucagon. Most of what I have heard is through Reddit communities for the on-market drugs (1st and 2nd gen peptides). The anecdotes from Retatrutide sound like it has way less impact on appetite and for some people that's actually a downside even though the weight loss effects appears to be significantly more powerful.
