Reported Benefits

Visceral fat reduction (HIV)

Strong Evidence 28 studies

Phase III: ~15% visceral fat reduction vs. placebo. FDA-approved indication.

NASH / liver fat reduction

Moderate Evidence 12 studies

Phase II (Stanley 2014): significant liver fat reduction and metabolic improvement.

Cognitive function (elderly)

Preliminary 6 studies

Small trials suggest executive function improvement via IGF-1 elevation.

Mechanism of Action

GHRH analog — stimulates pulsatile GH secretion, increasing IGF-1 and reducing visceral fat accumulation via GH's lipolytic effects.
