How Retatrutide compares

4 creators weighed in
G
GLP-1 Direct rival
weight loss drug class

Joe says standard GLP-1 drugs cause muscle and bone loss, while retatrutide lets you keep muscle mass.

"Huberman says he thinks retatrutide will be a trillion-dollar drug. What do you reckon about that?"

Discussed in the context of next-generation GLP-1 class drugs

Joe Rogan

"There's the retatrutide stuff. That one is a weird one because that one allows you to keep muscle mass. And that's the big fear that people have — is that you're starving yourself, but you're also losing bone mass and muscle mass."

Compared to standard GLP-1 drugs which cause muscle and bone mass loss

Andrew Huberman

"You probably know these as things like Ozempic, Mounjaro, and retatrutide"

Listed alongside Ozempic and Mounjaro as GLP-1 examples

Ozempic Direct rival
semaglutide weight loss drug

Joe says Retatrutide gives fat loss without muscle or bone loss that Ozempic causes. It also hits more body systems, making it the most effective GLP so far.

"Lilly developed retatrutide, which hits the GLP, GIP, and glucagon system, leads to the most robust weight loss, seems to spare some muscle, perhaps. People should always resistance train anyway to offset that, but it's the most effectiv..."

Compared to Ozempic and Mounjaro; hits GLP, GIP, and glucagon systems vs. fewer targets

Joe Rogan

"This one they think is going to be incredible because this one is going to give you all the fat loss but none of the muscle loss, none of the bone density loss."

Compared to Ozempic which causes muscle and bone loss

Tirzepatide Direct rival
approved GLP-1 weight loss drug

Retatrutide is not yet FDA approved, while Tirzepatide (Mounjaro) is already prescribed.

Compared to other GLP-1s; noted that Retatrutide is not yet FDA approved but Mounjaro (tirzepatide) is currently prescribed

vs: Contrasted with gray-market peptides sold as research chemicals

"There are people out there that think they're buying retatrutide. Yeah, no, they're not. Maybe use the GMP process as a way to explain why when you think you're buying retatrutide peptide for research purposes only, you are definitely not buying w..."

"Retatrutide is a triple agonist being developed by Eli Lilly. It hits three different receptor sites. It has less muscle wasting, much better safety profile, lower side effect profile, but people drop substantial amounts of body fat."

"We initially thought GLP-1's like Ozempic, Zepbound, and retatrutide just reduced food cravings. Now we know they work for alcohol and gambling and other addictions, too."
