Collagen Peptides- Summary
- CJC-1295 is a synthetic GHRH analog that stimulates the pituitary gland to produce and release growth hormone. The DAC (Drug Affinity Complex) version has a markedly extended half-life. The No DAC version (Modified GRF 1-29) preserves natural pulsatile GH release and is preferred in most protocols.
- Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
- Half-Life
- ~30 minutes (No DAC) / 6–8 days (with DAC)
- N/A — food-derived; absorbed peptides circulate for hours, depot accumulation in tissues
