CJC-1295 without DAC (also known as Modified GRF 1-29) is a synthetic peptide that mimics the action of growth hormone-releasing hormone (GHRH). It stimulates the pituitary gland to release growth hormone (GH) in a pulsatile manner, closely resembling the body’s natural GH secretion. Unlike CJC-1295 with DAC (Drug Affinity Complex), which extends the peptide’s half-life to days or weeks, CJC-1295 without DAC has a shorter half-life of about 30 minutes, leading to shorter but more frequent GH pulses. It’s typically administered via subcutaneous injection and is used in research settings for its potential metabolic and performance-enhancing effects.
