Usage Instructions
Commercially available DSIPs are mostly in lyophilized powder form and need to be reconstituted with a solvent before use. The standard procedure is to slowly inject the antibacterial solution (containing 0.9% benzyl alcohol) along the wall of the vial, avoiding direct impact on the powder. Allow it to stand until it dissolves naturally, gently swirling if necessary, but never shaking vigorously. The reconstitution concentration can be adjusted as needed; for example, 5 mg of powder added to 2.5 mL of solvent yields a 2 mg/mL solution.
Administration routes are primarily intravenous or subcutaneous injection. Early human sleep studies used intravenous infusion at a dose of approximately 25 nmol/kg. Subcutaneous administration has relatively low bioavailability, and experimental protocols commonly use a single dose range of 100–500 mcg. The timing of administration is relatively flexible; daytime administration can produce sleep improvement effects over several nights, without the need for immediate use before bedtime. Since current evidence does not clearly define the development of tolerability, it is recommended to start with a low dose and gradually adjust according to individual responses, avoiding blindly increasing the dose.
Application Scenarios
DSIP research applications focus on several areas. In the sleep field, it is suitable for models of sleep structure disorders and slow-wave sleep deficiency, characterized by improving sleep depth rather than simply shortening sleep latency. In pain management, a 1984 report in the European Journal of Neurology indicated its potential to alleviate migraines, vasomotor headaches, and psychogenic pain attacks. In substance withdrawal aids, studies from the same period showed that intravenous administration of DSIP rapidly relieved alcohol or opioid withdrawal symptoms, with efficacy rates of 97% and 87%, respectively. Furthermore, animal studies suggest it possesses antioxidant and anti-edema activities, possibly acting by activating endogenous antioxidant mechanisms or regulating the GABA/monoamine system. It is important to emphasize that most of the aforementioned human studies had small sample sizes, and evidence from modern large-scale randomized controlled trials remains scarce. DSIP should currently be considered an investigational neuromodulatory peptide, not a clinically established therapeutic drug.
Storage Method:
Unopened lyophilized powder: For long-term storage, keep at -20°C in a light-proof, sealed environment, away from moisture and light to maintain the activity of the raw material; for short-term storage (several weeks), refrigerate at 2-8°C.
Reconstituted solution: Aqueous stability decreases; use immediately if necessary. Remaining solution should be aliquoted, sealed, and stored at -20°C. Avoid repeated freezing and thawing, as this can easily cause peptide chain degradation and activity reduction.
Ensure proper sealing and moisture protection throughout packaging to prevent moisture ingress and powder deliquescence. Keep away from heat sources and do not store at room temperature for extended periods.
Label should indicate the preparation date. The reconstituted working solution should be used as soon as possible; long-term storage is not recommended.
