For a 200-pound patient, that translates to roughly 30 pounds lost
Victoza for diabetes (up to 1.8 mg), Saxenda for weight management (up to 3 mg) Oral GLP-1 option : Semaglutide (Rybelsus) is the only oral GLP-1 receptor agonist, taken once daily on an empty stomach with specific administration requirements: take with no more than 4 ounces of plain water, at least 30 minutes before eating, drinking, or taking other oral medications, and swallow tablets whole without breaking or chewing
Regulatory note: Injectable/IV NAD+ is not FDA-approved (or approved by any major regulator) for energy, metabolic or longevity uses
Tirzepatide may cause slightly stronger digestive symptoms early due to its dual-hormone action, while semaglutide may feel milder for some patients at first
Direct head-to-head trials are not yet available, but comparing across studies suggests retatrutide produces approximately 6-10 percentage points more weight loss than tirzepatide at equivalent treatment durations
As GLP-1driven weight loss scales across populations, the accompanying loss of muscle becomes a strategic vulnerability
