Some older studies measured early subjective or EEG changes.

Protocol / Research Dosing Guide
An evidence-organized Delta Sleep-Inducing Peptide reference separating small older IV trials from modern subcutaneous community protocols.
DSIP is a nine-amino-acid peptide first isolated during sleep research. Small studies from the 1980s tested intravenous administration in insomnia, with mixed findings and no modern confirmatory program.
Why researchers care
Sleep architecture, stress, and neuroendocrine research
Class
Delta sleep-inducing nonapeptide; emideltide
Route reported
IV in older human trials; subcutaneous use is community reported
Cycle length
Four-to-seven-night trials; longer community cycles unvalidated
Regulatory status
Not FDA approved; FDA Category 2 compounding concern
Older studies used 25 nmol/kg IV for four to seven nights. The supplied source separately reports 100–300 mcg subcutaneous evening use; that modern pattern is community reported, not trial validated.
| Phase or study | Amount | Frequency / evidence |
|---|---|---|
| Older trials | 25 nmol/kg IV | Four to seven nights; study design |
| Community lower range | 100–200 mcg SC | Evening; not validated |
| Community higher range | 200–300 mcg SC | Evening; sparse safety data |
Trial IV amounts and community subcutaneous microgram amounts use different units and routes and are not interchangeable.

| Route | Evidence context | Boundary |

| Intravenous | Small 1980s insomnia studies | Study setting only |
| Subcutaneous | Community reported | No validated clinical regimen |
| Oral or nasal | Not established | No validated exposure |
| Route conversion | Not established | nmol/kg IV cannot define SC mcg use |
Routes and amounts are not interchangeable unless a verified study explicitly establishes a conversion.
| Measure | Finding | Evidence limit |

| Human half-life | Not established | No robust modern PK study |
| Bioavailability | Not established | No SC exposure study |
| Blood-brain transport | Preclinical context | No quantitative human PK |
| Frequency | Evening use is community reported | Not pharmacokinetically derived |
| Route | Amount | Frequency | Source | Human validation |
|---|---|---|---|---|
| Intravenous | 25 nmol/kg | Four consecutive nights | Small human crossover study | Study design |
| Subcutaneous | 100–200 mcg | Once in evening | Community report | No |
| Subcutaneous | 200–300 mcg | Once in evening | Community report | No |
Published study values describe those studies. Community-reported values are not validated dosing recommendations.

DSIP was named after early delta-wave observations, but its mechanism remains unresolved.
