[ Research use only · Not for human consumption ]

CJC-1295 in Australia. CJC-1295 (no DAC) — also catalogued as Mod GRF (1-29) — is a 30-residue stabilised analogue of growth-hormone-releasing hormone (GHRH) referenced across growth-hormone-secretagogue research literature. This guide is a research-reference summary for Australian researchers, including the difference between the DAC and no-DAC forms and how the compound is paired with a GHRP in research. It makes no muscle, performance, or human-use claim.

What CJC-1295 (no DAC) is

CJC-1295 (no DAC) is a 30-residue synthetic analogue of the native hGRF(1-29) sequence — Mod GRF (1-29). It carries four stabilising substitutions on the GHRH(1-29) backbone (including D-Ala at position 2) plus a C-terminal amide, which slow enzymatic degradation while retaining GHRH-receptor-binding activity in research models. The value of that backbone chemistry was characterised by Soule and colleagues (The Journal of Clinical Endocrinology & Metabolism, 1994), who showed that incorporating D-Ala2 into GHRH(1-29) increases half-life and lowers metabolic clearance by blocking dipeptidyl-peptidase cleavage.

DAC vs no DAC — the distinction that matters

The “no DAC” label distinguishes this form from the DAC (drug-affinity-complex) variant. Jetté and colleagues (Endocrinology, 2005) identified CJC-1295 as an albumin-bioconjugated hGRF(1-29) analogue whose DAC group extends plasma persistence over days in research models, and Teichman and colleagues (The Journal of Clinical Endocrinology & Metabolism, 2006) reported the multi-day half-life of that DAC molecule. The no-DAC form referenced here carries the stabilising backbone substitutions but not the albumin-binding DAC group — so it is the shorter-acting, canonical reference version in GHRH research, and the form most frequently paired with a GHRP.

The GHRH + GHRP pairing

In the research literature CJC-1295 (no DAC) is most frequently studied alongside a GHRP — typically Ipamorelin, a selective ghrelin / GHS-R1a-receptor agonist. The canonical research pairing combines one GHRH analogue and one GHRP because the two receptor classes act on distinct, convergent points of the same somatotrophic-axis research model. For the co-lyophilised pairing in a single vial, see the CJC-1295 + Ipamorelin research blend and the research-stack guide.

Identity, purity and the COA moat

Every batch of CJC-1295 (no DAC) supplied by Elite AU Peptides is independently HPLC-tested by Janoshik before it is listed. The measured purity is published on the CJC-1295 (no DAC) product page and in the lab-reports library — real batch number, measured percentage, independently verifiable at janoshik.com. CJC-1295 (no DAC) is stocked in 5mg and 10mg lyophilised vials; nothing is listed without a certificate on file.

Reconstitution and handling for research use

CJC-1295 (no DAC) ships as a lyophilised powder. Reconstitute with bacteriostatic water for laboratory handling — for example, a 5mg vial in 2.5mL yields a 2mg/mL working stock. Store the lyophilised powder at −20°C protected from light; once reconstituted, refrigerate at 2–8°C and use within the documented research window, or aliquot and freeze to avoid repeated freeze-thaw cycles.

Compliance and research-use framing

CJC-1295 (no DAC) is not TGA-approved and is not a therapeutic good. Elite AU Peptides supplies it strictly for in-vitro and laboratory research use only — not for human or animal consumption. We make no medical, performance, muscle, or human-use claim; the material above summarises the published GHRH-analogue literature for reference only. Researchers should consult primary peer-reviewed sources for receptor-binding affinities and protocol-specific reference values.

[ Frequently asked ]

Growth-hormone research — questions researchers ask.

What is CJC-1295 (no DAC)?
CJC-1295 (no DAC) — also catalogued as Mod GRF (1-29) — is a 30-residue stabilised analogue of growth-hormone-releasing hormone (GHRH). The “no DAC” suffix indicates the standard form without the drug-affinity-complex modification. It is referenced across growth-hormone-secretagogue research literature. Elite AU Peptides supplies it strictly for in-vitro and laboratory research use only — not for human or animal consumption, not a therapeutic good, and not TGA-approved.
What is the difference between CJC-1295 with DAC and no DAC?
The DAC (drug-affinity-complex) modification adds an albumin-binding group that extends in-vitro half-life over days in research models — Jetté and colleagues (Endocrinology, 2005) characterised the albumin-bioconjugated form. The no-DAC form carries the stabilising backbone substitutions (including D-Ala at position 2, characterised by Soule and colleagues, JCEM, 1994) but not the DAC group, so it is the shorter-acting, canonical reference version of GHRH(1-29) in the research literature — and the form most frequently paired with a GHRP.
What research is CJC-1295 associated with?
CJC-1295 (no DAC) is referenced as a GHRH-receptor agonist in growth-hormone-secretagogue research. The value of its stabilising backbone chemistry — resistance to dipeptidyl-peptidase cleavage — was characterised by Soule and colleagues (JCEM, 1994). It is studied in vitro as a reference GHRH analogue, not as a treatment; no muscle, performance, or body-composition claim is made about it.
How does CJC-1295 pair with Ipamorelin?
The canonical research pairing combines a GHRH analogue (CJC-1295 no DAC) with a GHRP (Ipamorelin, a selective ghrelin / GHS-R1a agonist) because the two receptor classes act on distinct, convergent points of the same somatotrophic-axis research model. See the Ipamorelin product page for the standalone GHRP, or the CJC-1295 + Ipamorelin research blend for the co-lyophilised pairing in one vial.
Is CJC-1295 the same as the CJC-1295 + Ipamorelin blend?
No. This guide covers the standalone CJC-1295 (no DAC) compound. The co-lyophilised CJC-1295 (no DAC) + Ipamorelin research blend is a separate product — a single vial that reconstitutes both peptides together. See the CJC-1295 + Ipamorelin research-stack guide for that pairing.
How is research-grade CJC-1295 (no DAC) tested?
Every batch is independently HPLC-tested by Janoshik Analytical before it is listed. The measured purity is published on the product page and in the lab-reports library — a real batch number, the measured percentage, and an independently verifiable Janoshik report; nothing is listed without a certificate on file.
How is CJC-1295 (no DAC) shipped in Australia?
Stock is held and dispatched AU-domestic — no inbound customs handling. Free shipping over $100; orders placed before 12pm AEST are dispatched the same business day. Supplied strictly for laboratory research use only.
