What Is CJC-1295 DAC?
CJC-1295 DAC is the original compound developed under the CJC-1295 name by the Canadian company ConjuChem. It starts from the same modified GHRH chain as CJC-1295 No DAC: the first 29 amino acids of growth hormone releasing hormone, with four substitutions that protect it from enzyme breakdown. The difference is one addition at the end of the chain, a lysine carrying a reactive linker. That linker is the drug affinity complex, or DAC.
CJC 1295 With DAC: What the Drug Affinity Complex Does
Native GHRH lasts only minutes in circulation. The DAC changes that by forming a covalent bond with albumin, the most abundant protein in blood plasma. Once attached, CJC-1295 circulates with the albumin and is protected from clearance, so its half-life extends to roughly six to eight days.
That is the property researchers buy CJC-1295 with DAC for. A 2006 study in the Journal of Clinical Endocrinology and Metabolism reported that a single administration raised growth hormone levels for six days or more and IGF-1 levels for up to around eleven days in healthy adults. Instead of the natural pulse pattern, the DAC version produces a raised baseline, and that sustained elevation is what studies of it examine. Browse the papers in our CJC-1295 research library.
CJC-1295 DAC vs No DAC
| CJC-1295 DAC | CJC-1295 No DAC | |
|---|---|---|
| Also called | CJC-1295 with DAC | Modified GRF (1-29), Mod GRF |
| Albumin binding | Yes, via the DAC | No |
| Half-life | Roughly 6 to 8 days | About 30 minutes |
| Study design | Sustained elevation | Pulsatile release |
| Chainwell vial | 5mg | 10mg |
Our recommendation: choose CJC-1295 DAC only when your study needs growth hormone raised for days from one administration. For pulsatile work, and for pairing with ipamorelin, choose CJC-1295 No DAC. Our guide to CJC-1295 DAC vs no DAC covers the choice in more depth.
CJC-1295 DAC 5mg Vial
We supply CJC-1295 with DAC as a 5mg lyophilized vial, a 3 mL clear glass vial with a rubber stopper and purple flip-off cap. A 5mg fill suits a compound that stays active for days: a study period needs far fewer administrations of the DAC version than of the short-acting one.
To reconstitute, add bacteriostatic water slowly down the inside wall with a U-100 insulin syringe and swirl gently until clear. As a worked example, 2 mL in the 5mg vial gives 2.5mg per mL. Keep the reconstituted vial at 2 to 8 °C and use it within 28 days. Our reconstitution guide and calculator covers other volumes.
CJC-1295 DAC and Ipamorelin
Our CJC-1295 and Ipamorelin Blend uses the No DAC version, because its short half-life matches ipamorelin's. If your protocol specifically calls for CJC-1295 with DAC alongside ipamorelin, buy this vial and the ipamorelin vial separately, so each can be prepared and tracked on its own.
Lab-Tested CJC-1295 DAC With a COA
With and without DAC versions look identical in the vial, so identity testing is the only way to know which you have. Every Chainwell Peptide CJC-1295 DAC lot is sent to an independent laboratory before release: mass spectrometry confirms the molecular mass matches the DAC compound, and HPLC measures purity. A lot that does not meet specification is not sold. Check your lot on our COA lookup page.
Buy CJC-1295 DAC in Australia
Chainwell Peptide supplies CJC-1295 DAC in Australia to laboratories, universities and independent researchers. Before you buy CJC 1295 DAC from any supplier, check that the listing says "with DAC" in plain words, since many sell Mod GRF (1-29) under the CJC-1295 name, and that the certificate for your lot confirms it.

CJC-1295 With DAC FAQ
What is CJC-1295 DAC?
+
CJC-1295 DAC is a GHRH analogue built on the first 29 amino acids of growth hormone releasing hormone, with four substitutions and a drug affinity complex (DAC) that binds albumin. That gives it a half-life of roughly six to eight days. Chainwell Peptide supplies it as a 5mg lyophilized vial.
How long does CJC-1295 with DAC last?
+
CJC-1295 with DAC has a reported half-life of roughly six to eight days, because the DAC binds it to albumin in the blood. A 2006 study reported raised growth hormone for six days or more and raised IGF-1 for up to around eleven days after a single administration.
What is the difference between CJC-1295 DAC and no DAC?
+
CJC-1295 DAC binds albumin and lasts roughly six to eight days, suiting sustained elevation studies. CJC-1295 No DAC, also called Mod GRF (1-29), lasts about 30 minutes and suits pulsatile studies and pairing with ipamorelin. Chainwell Peptide sells both separately.
Can I buy CJC-1295 DAC with ipamorelin?
+
Our CJC-1295 and ipamorelin blend uses the No DAC version, because its short half-life matches ipamorelin. If your protocol calls for CJC-1295 DAC with ipamorelin, buy the 5mg DAC vial and the ipamorelin vial separately.
Where can I buy CJC-1295 DAC in Australia?
+
You can buy CJC-1295 DAC in Australia from Chainwell Peptide as a 5mg lyophilized vial. Every lot carries a lot number matched to an independent certificate of analysis, and orders paid before 3pm on a business day ship the same day by standard or express post.
