CJC-1295 vs MK-677
Both are gh secretagogue compounds. Here's how they line up on the evidence — graded the same way.
| CJC-1295 | MK-677 | |
|---|---|---|
| Evidence | 6/10 | 7/10 |
| Class | GH secretagogue | GH secretagogue |
| Summary | A long-acting GHRH analog that raises GH and IGF-1 in short human trials, but has no clinical-outcome data, is not FDA-approved, and is banned in sport. | MK-677 reliably raises growth hormone and IGF-1, but disease trials failed and one was stopped for a heart-failure signal. Investigational, never approved. |

CJC-1295 is a lab-made copy of a natural hormone called GHRH (growth hormone-releasing hormone — the signal that tells your body to make growth hormone). It's built to nudge your body into releasing more of its own growth hormone (GH). Short studies in people confirm it does raise GH and IGF-1 (a…
