DSIP vs Palmitoyl Tripeptide-1
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.
Full details →Palmitoyl Tripeptide-1
Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide that stimulates collagen production. It's one of two peptides in the Matrixyl 3000 complex, working synergistically with Palmitoyl Tetrapeptide-7.

| Aspect | DSIP | Palmitoyl Tripeptide-1 |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Very well-tolerated. Suitable for most skin types including sensitive skin. |
