Raised biomarkers are not proof of muscle gain.

Misleading
The circulating claim

“CJC-1295 and ipamorelin build muscle while you sleep.”

What the source record says

Human CJC-1295 research measured growth hormone and IGF-1. It did not demonstrate muscle gain, and PepCurrent found no human trial of the CJC-1295 and ipamorelin combination establishing that outcome.

Why the claim misleads

A hormone-level result is being converted into an unmeasured body-composition outcome.

Correction

Raised biomarkers are not proof of muscle gain.

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.
