DSIP vs Thymalin
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 →Thymalin
Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

| Aspect | DSIP | Thymalin |
|---|---|---|
| Mechanism | Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties. | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. |
| Typical Dosage | Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically. | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. |
| Administration | Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use. | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. |
| Side Effects | May cause grogginess upon waking, vivid dreams, or temporary headaches. | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. |
