GHRH
CJC No DAC
Modified GRF (1-29)
CJC-1295 without DAC, also known as Modified GRF (1-29), is a short-acting growth-hormone-releasing hormone (GHRH) analogue. The absence of the Drug Affinity Complex (DAC) is its defining feature: it produces a brief, pulse-like signal rather than the prolonged activity of the DAC-conjugated version, making it a preferred tool for studying natural GH-release rhythms.
In vitro and preclinical research focuses on GHRH-receptor binding, pulsatile GH-release pathway modeling, and IGF-1 signaling, often in combination models with ghrelin-mimetic secretagogues such as ipamorelin. Supplied as a lyophilized 10-vial kit in 5mg and 10mg sizes for in vitro research use only.

Common Questions
CJC No DAC FAQ
What is CJC No DAC?+
CJC No DAC is a Modified GRF (1-29) supplied for laboratory research. Short-acting GHRH analogue studied in vitro for natural pulsatile growth hormone release pathway modeling and IGF-1 signaling mechanism analysis.
What is the difference between CJC-1295 with and without DAC?+
CJC No DAC (also called Modified GRF 1-29) lacks the Drug Affinity Complex found in CJC-1295 with DAC. Without DAC it has a much shorter half-life, so research models show a more pulsatile growth-hormone-release profile rather than a sustained elevation.
What is lyophilized CJC No DAC, and how is it reconstituted?+
CJC No DAC is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should CJC No DAC be stored?+
Store the lyophilized CJC No DAC powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of CJC No DAC, and how is it tested?+
Every batch of CJC No DAC is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
