DSIP
DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide originally identified for its role in promoting deep, restorative sleep. Since its discovery in the 1970s, DSIP has been widely studied for its broader effects on the central nervous system, including stress modulation, hormone balance, and pain perception.
As a peptide linked to sleep regulation and neurological recovery, DSIP is being explored in research on sleep disorders, emotional regulation, and physical recovery—offering valuable insights into the relationship between rest, resilience, and brain health.

Delivery
Delivery
DSIP is supplied as a freeze-dried (lyophilised) powder. To use it, the peptide must first be reconstituted with bacteriostatic water. Learn how to activate this peptide.
This peptide is usually researched via subcutaneous injection, which means it’s delivered just under the skin using a small needle. Learn about subcutaneous injection.

Stacks well with
DSIP is a powerful sleep-support peptide designed to help your brain and body recover deeply and naturally. But for even better results, combining it with the right peptides can enhance emotional balance, cognitive function, and physical recovery. Whether you're managing stress, improving sleep quality, or supporting neurological health, the peptides below work synergistically with DSIP to help you rest, reset, and restore.
SEMax
Why it pairs well: SEMax enhances focus, memory, and neuroprotection during the day, while DSIP supports rest and recovery at night. Together, they provide a powerful 24-hour nootropic-restorative cycle, ideal for anyone looking to stay sharp and recharge fully.
Selank
Why it pairs well: Selank reduces anxiety, emotional stress, and nervous system overactivity. Stacking it with DSIP helps promote calmness and emotional stability, especially for those who struggle to “switch off” at night or experience stress-induced insomnia.
Epithalon
Why it pairs well: Epithalon supports pineal gland function and melatonin regulation, which enhances circadian rhythm alignment. When combined with DSIP, it offers a deeply regenerative anti-aging and sleep-support stack.
BPC-157
Why it pairs well: BPC-157 supports nervous system healing and reduces systemic inflammation. If poor sleep is related to injury, chronic pain, or stress, this stack helps the body recover both mentally and physically.
GHK-CU
Why it pairs well: GHK-Cu has calming, antioxidant, and neuroprotective properties. Stacking it with DSIP can improve restorative sleep, enhance brain repair, and promote general wellbeing, especially in high-stress or aging individuals.
