Substance P vs Ipamorelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Full details →Side-by-Side Comparison
| Aspect | Substance P | Ipamorelin |
|---|---|---|
| Mechanism | Binds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells. | Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones. |
| Typical Dosage | Not used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea. | Typical dosing ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. |
| Administration | Research compound only. Therapeutic applications focus on blocking rather than administering Substance P. | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. |
| Side Effects | Administration would cause pain, inflammation, and neurogenic responses. Not given therapeutically. | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. |
