The Claim
In adult male rats, acute infusion of GIP at 4 pmol/kg/min completely abolishes the insulin-induced enhancement of hindlimb muscle microvascular perfusion during a euglycemic hyperinsulinemic clamp, without altering serum insulin levels, indicating that GIP directly modulates the vascular effects of insulin in skeletal muscle.
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.
In male rats, a hormone called GIP can block insulin’s ability to increase blood flow to leg muscles, even when insulin levels stay the same — suggesting GIP directly interferes with how insulin works in the blood vessels of muscle.

What the research says
1 studyStudy: 109-OR: GIP Acutely Blunts Insulin- and GLP-1–Induced Muscle Microvascular Perfusion
The study shows that giving GIP to rats blocks insulin’s ability to increase blood flow in muscle, just like the claim says, and doesn’t change insulin levels.
