Core Effects

DSIP is an endogenous neuropeptide that is widely used in the treatment of sleep disorders, neuroprotective research, and circadian rhythm regulation due to its unique sleep regulation function and neuroprotective properties .

✅Sleep regulation mechanism :

Sleep induction : Promotes slow-wave sleep and increases deep sleep time.

Neuroprotection : Reduces stress hormones and protects neurons from damage.

Circadian rhythm regulation : Regulates the biological clock and improves the sleep-wake cycle.

✅Quality advantages of Chinese manufacturing :

Purity Guaranteed : Solid-phase synthesis process, purity ≥98%, single impurities ≤0.1%.

Sequence accuracy : The nonapeptide sequence is 100% correct.

Confirmation of activity : ED50 = 0.1 mg/kg in animal sleep experiments.

✅Global supply assurance :

Cold chain logistics : -20℃ cold chain transportation throughout the entire process to ensure product stability.

Multi-warehouse delivery : Regional warehouses are established in China, Europe, America, and the Asia-Pacific region, ensuring delivery within 7 days.

Customs clearance support : Professional document preparation ensures smooth customs clearance worldwide.
