9mRetatrutide is Lilly's investigational GIP, GLP-1 and glucagon receptor agonist. Understand the trial findings, how it differs from approved medicines, and why it is not available by prescription.
7mTwo of Lilly's next obesity drugs work in completely different ways. Here's how eloralintide (amylin) and retatrutide (triple agonist) compare on the published data.
8mWeekly vs monthly is the real MariTide comparison. Here's how Amgen's conjugate stacks up conceptually against weekly dual/triple agonists — without fake head-to-heads.
8mRetatrutide's hype is not just about weight loss. The bigger story is the way a triple agonist can feel different, from warmth and energy expenditure to the GI side effects that shape adherence.
7m31% body weight loss in a trial participant. Not an average — an individual result. But when 39.4% of Phase 3 participants on the 12mg dose hit the same milestone, the outlier becomes a pattern.
9mPhase 3 data is in: retatrutide produced an average 28.7% body weight reduction — roughly 71 lbs — in the TRIUMPH-4 trial. Here's what the numbers mean and how the triple agonist mechanism drives these results.
10mRetatrutide's triple receptor mechanism simultaneously suppresses appetite, enhances metabolic function, and activates thermogenesis. Here's the science behind why it delivers 24% body weight reduction.
12mRetatrutide is Lilly's investigational GIP/GLP-1/glucagon triple agonist. This hub covers what it is, what the trials actually reported about dosing and weight loss, how vial math works, where approval stands, and links to every retatrutide guide on PeptIQ.io.
9mRetatrutide is showing remarkable 2-year durability for weight loss. Here's what the science says and what it means for your protocol.
