DSIP vs GHK-Cu (Copper Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
DSIP
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.

| Aspect | DSIP | GHK-Cu (Copper Peptide) |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions. |
