Research Overview
CJC-1295 without DAC, also known as Mod GRF (1-29), is a modified 29-amino-acid analog of growth hormone-releasing hormone. Four amino acid substitutions in the sequence increase its stability against enzymatic degradation, while the omission of the drug affinity complex leaves it short-acting. It is used in in-vitro and preclinical research examining GHRH-receptor binding and pulsatile growth hormone signalling.
Quality & Testing
Every CJC-1295 (No DAC) batch is independently verified by an accredited third-party laboratory using HPLC (High-Performance Liquid Chromatography) and mass spectrometry to confirm both purity and molecular identity. Every order number is tracked internally against the supply-chain testing for the batches it shipped from — we don’t publish batch documents, which are routinely copied by other vendors. For testing information relating to your order, contact us with your order number.
Handling & Storage
CJC-1295 (No DAC) is supplied as a lyophilized (freeze-dried) powder. Store at -20°C and protect from light and moisture prior to reconstitution. For laboratory reconstitution volume and concentration calculations, see our Reconstitution Calculator.
