The Claim
Endogenous GLP-1 has a plasma half-life of approximately 2 minutes due to rapid degradation by the enzyme DPP-4, while exendin-4 is resistant to this enzymatic breakdown and demonstrates a significantly longer half-life in vivo.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Your body's natural GLP-1 hormone breaks down super fast—within minutes—because an enzyme chews it up, but exendin-4 (a similar molecule) lasts much longer because it can resist that breakdown.

Endogenous GLP-1 has a plasma half-life of approximately 2 minutes due to rapid degradation by DPP-4, whereas exendin-4 is resistant to enzymatic breakdown and exhibits a significantly prolonged half-life in vivo.
What the research says
1 studyThe study looks at a long-lasting diabetes drug made from exendin-4, which lasts much longer than natural GLP-1 because it isn’t broken down quickly in the body, supporting the idea that exendin-4 is more stable.
