Substance P vs Epithalamin

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.

Epithalamin

Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

Side-by-Side Comparison

AspectSubstance PEpithalamin
MechanismBinds primarily to NK1 receptors to transmit pain signals from peripheral nerves to the CNS. Also promotes inflammation, causes vasodilation, and stimulates immune cells.Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms.
Typical DosageNot used as a therapeutic agent. NK1 receptor antagonists (blocking Substance P) are used clinically for chemotherapy-induced nausea.Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols.
AdministrationResearch compound only. Therapeutic applications focus on blocking rather than administering Substance P.Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon.
Side EffectsAdministration would cause pain, inflammation, and neurogenic responses. Not given therapeutically.Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon.
