Overview
Cortexin is primarily a sleep & recovery peptide, while DSIP is used for pain management.
This page compares Cortexin and DSIP across their primary use, typical dosing, reported benefits and side effects, and U.S. regulatory status. For the full monograph on either compound — mechanism of action, clinical research, and references — follow the article links.
Side-by-side comparison
| Cortexin | DSIP | |
|---|---|---|
| Category | Sleep & Recovery | Pain Management |
| Regulatory status (US) | Research use only | Compounding (Rx) — Apr 2026 |
| Typical dosage | 10 mg | 100-300 mcg |
| Frequency | evening | daily |
| Reported benefits | Enhanced sleep quality, neural recovery, stress reduction | Pain threshold increase, stress-related pain reduction, better sleep despite pain |
| Reported side effects | Generally well-tolerated | Well-tolerated |
Key differences
Primary use. Cortexin is categorised under Sleep & Recovery, while DSIP falls under Pain Management. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. Cortexin: not FDA-approved; treated as a research compound. DSIP: not FDA-approved; compounding permitted with a prescription as of April 2026.
Dosing. Cortexin is typically dosed at 10 mg (evening). DSIP is typically dosed at 100-300 mcg (daily).
Can you stack them?
Some protocols combine peptides, but stacking Cortexin and DSIP has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
