Interaction evidence

These are general, pairwise evidence notes. Green identifies the potential-synergy category, while Lv3/Lv2/Lv1 communicates evidence strength; it does not guarantee benefit or cancel a safety warning.

With glucocorticoid replacement

Safety flag

GH-axis stimulation can reduce cortisone-to-cortisol conversion and unmask or worsen adrenal insufficiency.

Interaction evidence source

With glucose-lowering medicines

Safety flag

GH-axis stimulation can reduce insulin sensitivity and alter glucose control.

Interaction evidence source

With Ipamorelin

Safety flag

Duplicate GH/IGF-axis stimulation may amplify IGF-1 elevation, edema, joint symptoms, and glucose intolerance.
