PurposeSleep
MechanismDelta sleep–inducing peptide (experimental)
EffectsDelta sleep–inducing peptide (experimental)
DosingNo human dose established.
Bottom linePopular in research/compounding; human safety/benefit not well-established.
Protocols · as published2 sourced
Clinical trialChronic insomnia (Schneider-Helmert, 1981, n=6)
RouteIntravenous
FrequencyAcute
Starting25 nmol/kg IV
EscalationNone
TargetAcute dose; longer, less-interrupted sleep, no daytime sedation

Starting100-200 mcg SC ("most common community range"); no formal escalation
EscalationNone. Higher tier 200-300 mcg "used in some research write-ups".
Target100-300 mcg SC evening
CycleShort 5-7 nights; standard 4 weeks; extended 6-8 weeks

No SC human data.

Cautions & interactions

Not FDA-approved; limited evidence

No well-established interaction profile for non-approved peptides; avoid combining multiple research compounds; discuss meds with clinician.

CV 1 of 5 — No solid direct cardiovascular outcomes evidence; any benefit is indirect or unproven.
