The Claim

In healthy adult humans, intravenous infusion of GLP-1 at a rate of 1.2 pmol/kg/min for 150 minutes causes a significant increase in skeletal and cardiac muscle microvascular blood volume (MBV) and microvascular blood flow (MBF), with effects detectable within 30 minutes and sustained throughout the infusion period, indicating acute enhancement of nutrient and hormone delivery to muscle tissues via microvascular recruitment.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When healthy adults get a specific dose of a hormone called GLP-1 through an IV, it quickly boosts blood flow in the small vessels of their heart and muscles, helping deliver more nutrients and hormones where they're needed.

See the scientific wording

In healthy adults, intravenous infusion of GLP-1 at 1.2 pmol/kg/min for 150 minutes causes a significant increase in skeletal and cardiac muscle microvascular blood volume (MBV) and microvascular blood flow (MBF), with effects beginning within 30 minutes and persisting through 150 minutes, indicating that GLP-1 acutely enhances nutrient and hormone delivery to muscle tissue via microvascular recruitment.

What the research says

1 study
  1. Study: GLP-1 and Insulin Recruit Muscle Microvasculature and Dilate Conduit Artery Individually But Not Additively in Healthy Humans

    The study gave healthy people a specific dose of GLP-1 and found it increased blood flow and volume in muscle tissue quickly and kept it elevated, just like the claim says.
