Leuphasyl vs DSIP
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
Full details →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 →Side-by-Side Comparison
| Aspect | Leuphasyl | DSIP |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. |
| Typical Dosage | Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. |
| Administration | Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | May cause grogginess upon waking, vivid dreams, or temporary headaches. |
