Does Glucagon help with use for weight loss or body composition?

D
Grade D — no human evidenceNone · effect size: not measurable
Short answerNo human evidence. As of 29 October 2026, only none exist for Glucagon for use for weight loss or body composition. Glucagon receptor agonism is part of several investigational obesity drugs (survodutide, mazdutide, pemvidutide, retatrutide) because it raises energy expenditure. Glucagon itself has no trial as a weight-loss treatment, is given by emergency routes, and raises blood glucose — the opposite of what a diabetes treatment is for.

Animal studies, cell studies, or anecdotes only. This is where almost every viral peptide sits. Promising and proven are different words for a reason.

In context

Glucagon is the 29-amino-acid pancreatic hormone that mobilises stored glucose from the liver, and the emergency treatment for severe hypoglycaemia in people with diabetes. Modern formulations removed the reconstitution step that made the old kits hard to use in a crisis: a ready-to-use injection and a nasal powder. In a 75-person crossover trial the nasal powder raised blood glucose successfully at all but one dosing visit, against all visits for intramuscular injection. It is prescription-only everywhere LYO covers.

Glucagon is approved (rx). Legal status differs by country — see the regulation section or the jurisdiction pages.

Questions

Is Glucagon proven to help with use for weight loss or body composition?
No. There is no human evidence for it (None); the claim rests on animal or cell studies and LYO grades it D.
What studies are behind the grade?

Is Glucagon approved for this?
Glucagon is an approved medicine (Approved (Rx)); whether this particular outcome is a licensed indication is stated on the compound page's regulation section.
