CJC-1295 (no DAC) 10 mg

What is CJC-1295 (no DAC)?

CJC-1295 without DAC, also called modified GRF (1-29), is a growth-hormone-releasing-hormone analogue based on the first 29 residues of GHRH with four substitutions that resist enzymatic degradation. Without the drug affinity complex it does not bind albumin, so its half-life is measured in minutes rather than days. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.

What is CJC-1295 (no DAC) studied for?

• GHRH receptor binding assays
• Pulsatile growth-hormone release models
• Half-life comparisons against the DAC form
• Secretagogue combination studies

All applications above are in-vitro or preclinical research contexts. CJC-1295 (no DAC) is sold for laboratory research only and is not for human or animal use.

What does the certificate for lot CJC10-0803 show?

Every lot of CJC-1295 (no DAC) is tested by an independent US laboratory before it is listed. The report for lot CJC10-0803 is in the COA library and the lot number printed on the vial matches it. The current results:

Test	Method	Lot CJC10-0803 result

How is CJC-1295 (no DAC) handled and stored?

Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
