CJC-1295 (No DAC) FAQ: Your Questions Answered
The questions below are the ones that come up specifically about CJC-1295 (No DAC), rather than general peptide questions that apply to everything.
Overview
People ask what no DAC means, whether it is the same as Modified GRF 1-29 (yes), why it pairs with Ipamorelin, and how it differs from Tesamorelin.
What CJC-1295 (No DAC) actually is
A trimmed, stabilised piece of the natural growth-hormone-releasing hormone that nudges the pituitary to release GH in short, natural pulses. Leaving off the DAC part keeps it short-acting, which is what researchers study it for. Often searched as Modified GRF 1-29.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

CJC-1295 (No DAC) — common questions
What does no DAC mean?
The DAC (Drug Affinity Complex) version carries a group that binds albumin and stretches the half-life to days. Removing it leaves a short-acting molecule studied for producing tighter, more natural GH pulse patterns.
Is this the same as Modified GRF 1-29?
Yes. CJC-1295 without DAC and Modified GRF 1-29 refer to the same tetra-substituted GHRH(1-29) sequence.
Why is it studied with Ipamorelin?
They act through different receptors — GHRH receptor versus ghrelin receptor — so research designs often combine them to study complementary GH-release pathways.
Is it the same as Tesamorelin?
No. Both are DPP-4-resistant GHRH analogues, but Tesamorelin keeps the full 44-residue sequence with an N-terminal cap, while this molecule truncates to 29 residues and rebuilds stability through internal substitutions.
What CJC-1295 (No DAC) is studied for
Studied for prompting growth-hormone release in short, physiological pulses via the GHRH receptor.
The four substitutions are studied for extending the molecule beyond the minutes-long survival of native GHRH.
Frequently studied alongside ghrelin-receptor secretagogues such as Ipamorelin, which recruit a second GH-release pathway.
