CJC-1295 with DAC vs. without DAC: What Buyers Should Know

What DAC Means

DAC stands for drug affinity complex. In CJC-1295 with DAC, it is a reactive maleimide-based group attached through an extra lysine at the end of the peptide chain. CJC-1295 without DAC is the modified GHRH analogue on its own, with no such group; it is often catalogued as modified GRF (1-29).

The difference is chemical, not a matter of strength or grade. Adding the group changes the molecule, so the two are separate materials. DAC is not a separate ingredient in the vial: it is part of the compound it is attached to.

Two Compounds, Two Sets of Identity Data

• Different molecular formula and weight. A supplier's page should give the identity data for the version it sells, not a mix of both.
• A different mass on the identity test. An LC-MS or UPLC/MS identity result that matches one version does not confirm the other.
• Names that blur. "CJC-1295" with no qualifier can mean either. Treat an unqualified name as unconfirmed until the supplier says which compound it is, in writing.
• Blends. A blend label that says "CJC-1295" should say which version it contains. Our blend's listed composition names CJC-1295 (No DAC).

Names You May See

The same two compounds appear under several names across suppliers, and the naming is not always consistent. Read each one as a prompt to confirm, not as proof of which compound is in the vial.

• CJC-1295 no DAC, CJC-1295 without DAC, modified GRF (1-29), mod GRF 1-29. Usually the version without the drug affinity complex.
• CJC-1295 with DAC, CJC-1295 DAC. The version with the drug affinity complex attached.
• CJC-1295 on its own. Ambiguous. Some suppliers use it for one version, some for the other.

What We List

We list CJC-1295 no DAC in a 10 mg vial, and the blend CJC-1295 + Ipamorelin, 10 mg total in one vial: 5 mg of CJC-1295 (no DAC) and 5 mg of ipamorelin. Both are in the GHRH and GH secretagogues class.

We don't list a version with DAC. It can be quoted on request, as we source compounds beyond the catalog; the quote will name the compound, and you should ask for its identity data and the report for its lot.

Common Labelling Mistakes to Catch

If you sell under your own brand, the white label proof is the place to catch a missing qualifier: check the compound name on the proof against the quote, word for word.

• A label that drops the qualifier. The quote says no DAC, the vial says only CJC-1295. Ask for labels that match the quote before the order ships.
• A report for the other version. The identity result matches the version you didn't order. That report doesn't cover your vials.
• A blend with an unqualified component. The composition lists CJC-1295 without saying which version. Ask before you list the blend.
• Your own catalog copy. A product page titled CJC-1295 that links a no-DAC report confuses buyers. Use the full name everywhere: page title, SKU, label and report reference.

Reading the Report for the Right Compound

The report on our CJC-1295 no DAC page is a reference report: it comes from a batch shared with a partner, covers a 5 mg vial while we sell 10 mg, and gives an identity result with no purity figure. Ask for the report for your lot. The blend's report is on its product page. How to read a peptide certificate of analysis explains each line, and reference COAs vs. batch-matched COAs explains why a reference report doesn't cover your order.

• The compound name as printed, including DAC or no DAC.
• The labelled size, matching what you're buying.
• A batch or lot number, the same one printed on your vials.
• An identity result that matches the compound on the quote.
• For a blend, each component, and whether any purity figure is an average across them.

Research Publication Statistics

Our CJC-1295 no DAC research statistics page shows how much has been published, by year and study type, with the PubMed search shown so you can check it. Because the two versions share a name, read the search terms shown on the page to see what the count includes. The page describes the literature only, not the material or what it does. Other compounds are on the research hub.

If You Resell Either Version

Give each compound its own product page, SKU, label and report, and never let one page stand in for both. A buyer looking for the version with DAC who lands on a no-DAC page, or the reverse, should be able to tell from the title alone.

Publish the report for the lot you are selling, with the compound name exactly as printed on it, and keep reports available after a lot sells out. Describe each version by name, identity data, size and documentation only, with the research-use-only statement visible. Planning a product catalog and COA library covers how to keep products, lots and reports in step.

Questions to Ask Before You Order

• Which compound is quoted: with DAC or without?
• Will the vial label carry the full name, including the qualifier?
• Does the identity result on the report match the compound on the quote?
• Which lot will I receive, in which size, and can I see its report before I pay?
• For the blend, does the composition name the version of CJC-1295 it contains?

Getting a Quote

Name the compound in words when you ask: CJC-1295 no DAC, the CJC-1295 + Ipamorelin blend, or CJC-1295 with DAC. Add it to your list in the catalog and send it on WhatsApp or by email, or write the DAC version into the message. Every wholesale lot comes with a certificate of analysis, and the quote names the compound, the lot and its report. Wholesale stock ships from Tampa Bay, Florida, to the United States; factory-direct orders can ship internationally. Every published report is in our COA library.

Moving from another supplier? Send their label or report with your request, and we'll confirm which compound it names before we quote.
