CJC-1295 with DAC at a glance

Developed by the Canadian company ConjuChem, CJC-1295 is a tetrasubstituted GHRH(1-29) analogue with an extra C-terminal lysine bearing a maleimidopropionic acid group. That group, the Drug Affinity Complex, reacts with a free cysteine on serum albumin after the peptide enters the bloodstream, effectively tethering a small peptide to a large, long-lived carrier protein. Its molecular weight is about 3647 g/mol, considerably heavier than the unconjugated fragment sold as CJC-1295 No DAC.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

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.

What it is studied for

Pharmacologically, the target is the same GHRH receptor on anterior pituitary somatotrophs that sermorelin and Modified GRF (1-29) activate. What changes is the time course. Once attached to albumin, the peptide escapes rapid renal filtration and enzymatic cleavage, so receptor stimulation is spread over days in published pharmacokinetic studies. Investigators have reported that baseline growth hormone levels rise while some pulsatility is preserved, and that circulating IGF-1 increases in turn. Whether prolonged exposure alters receptor sensitivity over time is one of the questions such studies address.

Research and regulatory status

Early studies in healthy adults described extended elevation of growth hormone and IGF-1 after single and repeated administration. Clinical development was later discontinued, and the compound never progressed to approval. Since then, the literature has stayed small, and much online discussion conflates this molecule with the No-DAC fragment. Anti-doping agencies list it among prohibited GH-releasing factors. Researchers should treat it as an experimental tool with limited long-term data.

Checking the lab data

The deciding measurement is mass: a deconvoluted mass-spectrometry result near 3647 Da confirms the DAC-bearing lysine is present, whereas a value near the mass of Modified GRF (1-29) would indicate the wrong product. The maleimide group is reactive, so degradation products may appear as extra chromatographic peaks; HPLC purity should state its method. Batch number, test date and lab name complete the record. Expect a white lyophilized cake.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 5 mg vial dissolved in 2 mL gives 2.5 mg/mL, or 5 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

What does the maleimide group actually bond to?

Maleimides react selectively with thiol groups. In plasma, the most available free thiol belongs to a single cysteine residue on albumin, so the DAC linker forms a stable covalent bond there. The same chemistry explains why the reactive group can degrade in storage or react with other thiols if a sample is handled carelessly.

Is the DAC approach used for other peptides?

Yes. ConjuChem applied the same Drug Affinity Complex strategy to other peptide candidates, including GLP-1-related molecules, as a general way of extending circulation time. In research catalogues, though, the phrase with DAC almost always refers to this GHRH analogue, so listings should give the full name and expected mass.

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

One vial of 5mg. Where a lab report exists, the testing panel above shows the measured content of the tested sample.

When does Cyprus Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
