CJC-1295 vs Selank
Side-by-side comparison of key properties, dosing, and research.
- 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.
- Selank is a synthetic heptapeptide analog of tuftsin developed in Russia. It is a potent anxiolytic that reduces anxiety and enhances cognitive function without sedation or addiction. It is approved for clinical use in Russia for anxiety disorders.
