Side-by-side comparison
| Cortexin | Melatonin Peptide Complex | |
|---|---|---|
| Category | Sleep & Recovery | Sleep & Recovery |
| Regulatory status (US) | Research use only | Research use only |
| Typical dosage | 10 mg | 3-10 mg |
| Frequency | evening | before bed |
| Reported benefits | Enhanced sleep quality, neural recovery, stress reduction | Sleep onset improvement, circadian support, antioxidant effects |
| Reported side effects | Generally well-tolerated | Possible morning grogginess |
Key differences
Primary use. Cortexin is categorised under Sleep & Recovery, while Melatonin Peptide Complex falls under Sleep & Recovery. Because they target a similar goal, they are common alternatives to weigh against each other.
Regulatory status. Cortexin: not FDA-approved; treated as a research compound. Melatonin Peptide Complex: not FDA-approved; treated as a research compound.
Dosing. Cortexin is typically dosed at 10 mg (evening). Melatonin Peptide Complex is typically dosed at 3-10 mg (before bed).
Can you stack them?
Some protocols combine peptides, but stacking Cortexin and Melatonin Peptide Complex 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.
