What is DSIP?
DSIP is a naturally occurring nonapeptide first characterized in research into slow-wave sleep regulation, from which it takes its name. It is studied within the neuropeptide research literature for its interaction with sleep architecture, circadian regulation, and stress-response pathways. DSIP is supplied strictly for laboratory and research use, and is intended exclusively for handling by licensed, qualified professionals under appropriate regulatory frameworks.
Benefits and Uses
Available research on DSIP spans several areas of interest, with the caveat that large-scale human clinical trial data remains limited and a number of proposed mechanisms are not yet firmly established:
- Sleep architecture. The most extensively studied application; DSIP has been investigated for its role in promoting slow-wave (delta) sleep in laboratory models.
- Circadian regulation. Research has examined DSIP’s relationship to circadian rhythm balance alongside its sleep-architecture effects.
- Stress-response modulation. Research has examined DSIP’s interaction with neuroendocrine stress pathways and adaptive response.
- Cognitive and neuroendocrine function. Some studies have investigated DSIP’s relationship to neuroendocrine signaling relevant to cognitive performance, though this area is less well established than the sleep-related research.
How It Works
DSIP’s precise mechanism has not been fully mapped. Laboratory research associates it with promotion of slow-wave sleep and interaction with systems governing circadian rhythm and stress adaptation, but the specific receptor targets and signaling pathways involved remain an open area of study rather than a settled model.
Dosage and Administration
No standardized dosing protocol exists for DSIP outside of individual study designs, and any research protocol, route, or dose is determined solely by the licensed researcher or practitioner and their institution.
For reference, early human studies most frequently administered DSIP via intravenous infusion at approximately 25 nmol/kg body weight — this reflects historical study design, not a recommended or current protocol.

Side Effects and Safety
Across the studies referenced below, DSIP has generally been reported as well tolerated in research settings, with few significant adverse effects noted in short-term human trials. Long-term human safety data remains limited. Researchers typically establish baseline laboratory values, such as metabolic and liver-function panels, before and during a study protocol to monitor safety markers. Animal studies have generally reported a favorable tolerability profile for Tβ4. Direct long-term human safety data specific to the TB-500 fragment does not exist in the published literature, and researchers should establish baseline laboratory values before and during any protocol.
Quality & Verification Standards
Every
CellGenic lot is manufactured under cGMP conditions and undergoes mycoplasma, sterility, identity, and potency testing prior to release.
Certificates of Analysis are issued per batch and can be retrieved directly using your batch number.
DSIP in CellGenic's Sleep and Longevity Protocol
Within CellGenic’s own provider protocols,
DSIP is paired with
CJC-1295/Ipamorelin and
Epithalon to support GH pulsatility, sleep architecture, and longevity tone as a combined research protocol — rather than being studied in isolation. Providers building a sleep- or longevity-focused protocol can review the full pairing and its component products directly.
