What the studies show

No trial has measured muscle or fat change.

Animal studies, cell studies, or anecdotes only. This is where almost every viral peptide sits. Promising and proven are different words for a reason.

In context

CJC-1295 is a modified growth-hormone-releasing hormone fragment engineered to bind albumin so that it lasts days rather than minutes. Early human trials showed substantial, sustained rises in growth hormone and IGF-1 with weekly dosing. Development was discontinued and no trial has measured whether that translates into any clinical outcome. It is not approved anywhere and is banned in sport.

CJC-1295 is not approved. Legal status differs by country — see the regulation section or the jurisdiction pages.
