CJC-1295 vs Dihexa

Side-by-side comparison of key properties, dosing, and research.

Growth Hormone Peptides
CJC-1295
Cognitive Enhancement
Dihexa
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.
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
