Source record · Animal study · reviewed July 16, 2026

The cited animal study pushes back on the claim, but human effects remain inadequately characterized.

Misleading
The circulating claim

“Ipamorelin spikes prolactin and cortisol like other GH peptides.”

What the source record says

The original characterization study found no significant ACTH or cortisol increase in swine, even at high experimental doses. That is animal evidence, not proof of the same result or a complete hormone profile in people.

Why the claim misleads

The claim overstates one direction; the correction must not overstate the opposite direction.

Correction

The cited animal study pushes back on the claim, but human effects remain inadequately characterized.

What changed

Added the source-verified Claim Check to the structured claim/source/change registry.

What would change our answer

A well-controlled human study tied to the exact product, population, route, and claimed outcome could change the answer. Mechanism, anecdotes, or a different product cannot substitute for that evidence.
