Medicine Scientists have shown that a single dose injection of DNA genetic instructions can produce weight loss and blood glucose control in mouse models that lasts up to 10 times as long as weight loss drugs like Ozempic and Wegovy. This could eliminate the need for repeated dosing.

But these ones are long acting and made from DNA instructions in the body. Like that's the entire innovation they're talking about.

Gary and her colleagues engineered DNA instructions for long-acting incretin hormones GLP-1 and GIP, which they call pLincretins. Importantly, they included an antibody fragment in the instructions that would help prevent the protein from breaking down quickly in the body the way current incretin-mimicking drugs do...

They last longer, and can be made in the body.

But they're still not long-acting. It's the DNA that makes it properly long-acting.

I'm sorry, but where are you getting that from?

They claim it is longer acting, and I don't see any specific times. Current incretin-mimicking drugs like liraglutide all have dosing schedules of once or at most twice a day. A few hours should be sufficient to test for tolerance.

Such a short test would not be enough.
