CJC-1295 vs Substance P

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

CJC-1295

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.

Substance P

Substance P is an 11-amino acid neuropeptide involved in pain transmission, inflammation, and various neurological processes. While not used therapeutically itself, understanding it is crucial for pain research.

Side-by-Side Comparison

AspectCJC-1295Substance P
MechanismCJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly.Binds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells.
Typical DosageCJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily.Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea.
AdministrationSubcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.Research compound only. Therapeutic applications focus on blocking rather than administering Substance P.
Side EffectsWater retention, tingling in extremities, potential increase in cortisol and prolactin levels.Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically.
