CJC-1295 2mg (no DAC)

CJC-1295 without DAC, also called Mod GRF (1-29), is a modified analogue of the first 29 amino acids of growth hormone-releasing hormone (GHRH). Four amino-acid substitutions give it greater stability than the native sequence in the lab. It is supplied as a lyophilised powder in a 2mg vial.

Research context

As a GHRH analogue, CJC-1295 (no DAC) is used in research on the GHRH receptor and growth hormone secretion. It is often studied alongside ghrelin-receptor agonists such as Ipamorelin, since the two act on different receptors. "No DAC" means it lacks the drug affinity complex that extends the half-life of CJC-1295 with DAC.

Quality and testing

FAQs

What purity is this batch?
The current batch of CJC-1295 (no DAC) tested at 99.02% by HPLC, with identity confirmed by mass spectrometry. The full certificate of analysis, number 026-C82-TSX, is shown below and can be downloaded.

What is the difference between CJC-1295 with and without DAC?
DAC (drug affinity complex) is a chemical group that binds albumin and greatly extends the peptide's half-life. This product is the version without DAC, also known as Mod GRF (1-29). We do not currently stock CJC-1295 with DAC.

How should it be stored?
Keep the sealed vial at 2–8°C for short-term storage or at −20°C for long-term storage, away from light and moisture. Let a cold vial reach room temperature before opening it.

Is this the same as CJC1295?
Yes. CJC-1295 (no DAC) is also written or searched for as CJC1295, CJC 1295, CJC-1295 without DAC, Mod GRF 1-29 or modified GRF (1-29). All of these names refer to this GHRH analogue.
