What is CJC-1295 with DAC?

CJC-1295 with DAC is a tetrasubstituted variant of GHRH(1-29) carrying a maleimide-linked lysine, the Drug Affinity Complex, that forms a covalent bond with circulating albumin. This albumin conjugation is the key structural feature distinguishing it from unmodified GHRH fragments such as sermorelin, and it is what researchers credit for its extended presence in circulation.

How it is understood to work

By binding pituitary GHRH receptors, CJC-1295 with DAC is studied for its ability to stimulate synthesis and release of growth hormone, which in turn drives hepatic IGF-1 production. Because the peptide remains bound to albumin rather than being rapidly cleared, researchers use it to model sustained, rather than short-pulse, GHRH receptor activation.

Research status

Most published data come from pharmacokinetic and endocrine studies in animal models and small early-phase human investigations examining GH and IGF-1 elevation over extended periods; it has not advanced to an approved therapeutic product, and long-term outcome data remain limited.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: CJC-1295 with DAC
Also known as: DAC:GRF, Drug Affinity Complex GHRH
Class: Long-acting GHRH(1-29) analogue
Form: Lyophilized (freeze-dried) powder
Per vial: 5mg
Molecular formula: C₁₆₅H₂₆₉N₄₇O₄₆
Molecular weight: 3647.2 g/mol
Stated purity: ≥99% (HPLC)

Handling & storage

Supplied as a lyophilized powder; store at -20C protected from light, and once reconstituted with bacteriostatic water keep refrigerated at 2-8C for use within the study’s defined timeframe.

Concentration check: adding 2 ml of bacteriostatic water to one 5 mg vial gives 2.5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How is CJC-1295 with DAC different from CJC-1295 without DAC or sermorelin?

The DAC modification adds a covalent albumin-binding group that extends the peptide’s circulating half-life from minutes to roughly a week in research models, whereas plain CJC-1295 and sermorelin are cleared much faster and are used to model shorter, pulsatile GHRH activity.

What should a COA confirm for this peptide?

Molecular weight near 3647 g/mol, HPLC purity of 99% or higher, and mass-spec identity confirmation, since the DAC-conjugated structure is more complex than a standard peptide and easier to mischaracterize on lower-resolution testing.

How much CJC-1295 with DAC is in this kit?

10 vials of 5 mg each, so 50 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
