Quick answer

What is CJC-1295?

Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk. No qualified clinical reviewer. How this site works

CJC-1295 is a peptide, grouped on this site under GHRH analogues, and the 12 research records kept here are 2 from studies in rats or mice, 2 from trials in people and 8 that do not state what kind of study it is.

The literature search returned 36 records. This site keeps 12 of them, which is 33 per cent of what came back.

What it is

This site puts it in the GHRH analogues group.

A long-acting GHRH analogue that activates the GRF receptor; the retrieved literature attributes its extended duration of action to albumin bioconjugation.[1, 2]

Stated in the titles of the cited 2005 Endocrinology and 2009 Growth Hormone and IGF Research papers.

What kind of records

A small number of the records kept here are trials in people.

That sentence is produced by counting, not by reading. What was counted: 2 interventional human trial records among 12 indexed records.
