Sermorelin vs CJC-1295. The legal one vs the restricted one.

Both nudge your own growth-hormone axis, but only one can be legally compounded in the US today. The honest difference, side by side.

SermorelinGHRH analog · available now
What it does

Used to support muscle, recovery, and sleep quality.

Best evidence

Grade C, moderate clinical history as a GHRH analog; outcome data is limited.

What we don't know

Long-term outcome data is limited; effects vary with age and baseline.

CJC-1295GHRH analog · Category 2 (non-compoundable)
What it does

Studied as a GH-axis stimulator for recovery and body-composition interest.

Best evidence

Grade C, modest human GHRH-analog data; long-acting (DAC) variants less characterized.

What we don't know

Long-term safety of the long-acting (DAC) form is poorly characterized in humans.

How to think about choosing

This is the cleanest example of our two-signal rule. Sermorelin and CJC-1295 are close cousins, both GHRH analogs that prompt your own GH release. The difference isn't really the molecule; it's the law. Sermorelin is 503A-eligible and available under a clinician; CJC-1295 has sat on FDA compounding Category 2 since 2023 and cannot be legally compounded. If you want the GH-axis effect through a legitimate route, the answer is Sermorelin.

At a glance
Sermorelin
CJC-1295
What it is
Sermorelin is a synthetic analog of growth-hormone-releasing hormone (GHRH 1–29). It signals the pituitary to produce and release the body's own growth hormone, rather than introducing growth hormone directly.
A long-acting GHRH analog that stimulates pituitary growth-hormone release, often combined with a GH secretagogue like Ipamorelin.
What it's for
Used to support muscle, recovery, and sleep quality.
Studied as a GH-axis stimulator for recovery and body-composition interest.

The honest caveat

Popularity doesn't change legality: CJC-1295 earns far more searches than it can legally fulfill. Neither is an anabolic shortcut, both are WADA-banned (S2), and Sermorelin's own outcome data is moderate. We route you to the legal option rather than the loud one.

Common questions

Is sermorelin the same as CJC-1295?

They're close cousins, both GHRH analogs that stimulate your own growth hormone. The practical difference is regulatory: sermorelin is 503A-eligible and available under a clinician; CJC-1295 is FDA compounding Category 2 and cannot be legally compounded in the US.

Why is CJC-1295 not available?

The FDA placed CJC-1295 in compounding Category 2 in September 2023, meaning it cannot be legally compounded. The legal GH-axis route is sermorelin.
