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.

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.

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.

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.

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.
