- Primary Mechanism
- GABAergic potentiation + mu-opioid receptor modulation in VLPO
- MAO-A/B modulation + BDNF upregulation in hippocampus/PFC
- Non-overlapping. DSIP targets sleep circuits; Selank targets monoamine dynamics
- Receptor Targets
- GABA_A receptors, mu-opioid receptors, adenosine A1
- Indirect monoamine (5-HT, DA, NE) via MAO inhibition
- Selank doesn't bind sleep-related receptors; DSIP doesn't modulate monoamine pathways
- Optimal Administration Window
- 30–60 minutes before intended sleep onset
- Morning or early afternoon during waking hours
- Circadian timing is the deciding factor. Wrong timing = zero efficacy for either compound
- Half-Life vs Effect Duration
- 15–20 min plasma; 6–8 hr delta-wave effect
- 20–30 min plasma; 4–6 hr anxiolytic effect
- Both trigger downstream cascades that outlast their plasma presence
- Typical Research Dosing
- 100–500 mcg subcutaneous, single evening dose
- 250–1,000 mcg subcutaneous or intranasal, morning/midday
- DSIP requires lower absolute dose; Selank tolerates wider dosing range
- Reconstitution & Storage
- Bacteriostatic water, 2mg/mL, refrigerate 2–8°C
- Bacteriostatic water, 2.5mg/mL, refrigerate 2–8°C
- Both require identical cold-chain handling. Any temperature excursion denatures protein structure
- Primary Research Applications
- Sleep fragmentation, restorative deficit, stress-induced insomnia
- Cognitive stress resilience, anxiolytic studies, neuroplasticity under demand
- Choose based on biological state being modulated, not 'better/worse' hierarchy
