DSIP vs Epithalamin
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 →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.
Full details →Side-by-Side Comparison
| Aspect | DSIP | Epithalamin |
|---|---|---|
| Dose Range | 100 mcg–300 mcg | 5 mg–10 mg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 1–6 weeks | 1–2 weeks |
| Route | subcutaneous | intramuscular |
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
