Tirzepatide (GLP-2) has already set a new standard in weight loss as a dual-agonist, targeting both GLP-1 and GIP to help control appetite, improve metabolic function, and drive meaningful weight loss. For many people, it represents one of the most effective options currently available.But Retatrutide (GLP-3) takes things a step further.We explain how Retatrutide builds on the same foundation as Tirzepatide, but adds a third pathway through the glucagon receptor. That additional mechanism may increase energy expenditure and fat loss, creating a more complete metabolic response rather than relying primarily on appetite suppression alone.Throughout the episode, we compare how each compound works, what that means for weight loss outcomes, and why Retatrutide is being viewed as the next evolution in GLP-1-based therapy. We also cover the key distinction that matters right now: Tirzepatide is available and FDA-approved, while Retatrutide is still in clinical trials.If you are trying to understand where the future of weight loss is headed and how these compounds stack up side by side, this episode gives you a clear and straightforward comparison without the hype.
