CJC-1295 sans DAC
The signal the body sends itself — measured in humans, against placebo.
10 mg

The body triggers its own growth hormone from a signal it sends itself; CJC-1295 reproduces that signal. “Without DAC” means the short version — the one that does not linger in the blood — and it is this distinction that is studied.
- The short version: deliberately brief action.
- The path the body already uses, not a hormone brought in from outside.
- Measured in humans, against placebo.
What is being looked at?
- The body’s own signals

The question you are asking yourself
Is this growth hormone?
No. It is the signal that triggers it, not the hormone itself — and the distinction is not cosmetic: what is studied here is the pathway the body already uses. What was measured are hormonal markers, not a clinical improvement.
Why this reference?
The body has its own command signal for growth hormone. This reference exists to study it. A placebo-controlled trial published in an endocrinology journal measured, in healthy volunteers, a rise in those hormone markers over several days. Those are markers, not a demonstrated clinical improvement.
What you should know
Scientific detail
What it is
CJC-1295 without DAC is a synthetic analogue of the first twenty-nine amino acids of GHRH, the hormone that triggers growth-hormone release. "Without DAC" means it lacks the group that, in the other version, extends its presence in the blood.
Why it is studied
GHRH acts on a specific pituitary receptor. A short analogue makes it possible to study that pathway without reproducing the duration of action of the whole hormone.
Described mechanism
Proposed mechanism: binding to the GHRH receptor. The short half-life is a property of the molecule, not a demonstrated advantage.
What the research has studied
- GHRH pathway
- Release pathway
- Duration of action
Human data
A randomised, double-blind, placebo-controlled trial published in 2006 in the Journal of Clinical Endocrinology & Metabolism measured, in healthy adults, GH elevations of 2- to 10-fold and IGF-1 elevations of 1.5- to 3-fold, lasting 9 to 11 days after a single dose. These are hormonal markers measured in healthy volunteers — not a demonstrated clinical benefit.
Preclinical data
Preclinical work on receptor binding and growth-hormone release.
What the data does not say

Frequently asked questions
Can I order CJC-1295 sans DAC today?
No. This reference is not offered for sale: its commercial framework is not settled. No purchase button is shown until it is.
Does CJC-1295 sans DAC hold a marketing authorisation?
No. This reference holds no marketing authorisation as a medicinal product and is approved by no authority for human use. A publication or a clinical trial never amounts to approval.
What analyses are available?
The certificate of analysis is supplied with the batch delivered. No batch number or purity figure is published until the real certificate has been entered: we do not display illustrative values.
How is this reference stored?
The storage requirement is not yet on file: the supplier data sheet has not reached us. We would rather say so than assume.
Is it compatible with the NORYVA injector pen?
Compatibility is not confirmed for this reference. Until the manufacturer confirms it, we do not claim it.
What does the available data actually show?
The DAC and non-DAC versions are frequently confused in commercial presentations. No marketing authorisation.
