- DSIP (Delta Sleep-Inducing Peptide)
- GABAergic modulation, HPA axis suppression, cytokine reduction
- N/A. Reference compound
- Establishes sleep architecture, reduces stress-induced cortisol, suppresses inflammatory wake signals
- Avoid with GABA antagonists, opioid blockers, high-dose corticosteroids
- Best standalone sleep peptide for stress-related insomnia; requires functional HPA axis to be effective
- Epithalon
- Telomerase activation, pineal gland function, melatonin regulation
- Complementary. Non-overlapping pathways
- DSIP improves sleep depth while Epithalon normalizes circadian melatonin rhythm; combined use supports both sleep quality and circadian timing
- No direct contraindication; stagger dosing (Epithalon evening, DSIP 60–90 min before sleep target)
- Excellent combination for circadian disruption models; Epithalon addresses timing, DSIP addresses depth
- Selank
- Anxiolytic via GABA and serotonin modulation, immune regulation
- Partially overlapping. Both enhance GABAergic tone
- Synergistic anxiolytic effect; Selank's longer half-life (hours vs minutes) extends DSIP's acute calming phase
- Monitor for excessive sedation; reduce DSIP dose by 20–30% if combining in anxiety models
- Use Selank for daytime anxiety regulation, DSIP for nighttime sleep induction. Sequential rather than concurrent dosing preferred
- Semax
- Nootropic, BDNF upregulation, mild stimulant properties
- Opposing circadian effects
- Semax promotes wakefulness and cognitive arousal; DSIP promotes sleep. Use at opposite ends of circadian cycle
- Avoid concurrent dosing; Semax in morning, DSIP in evening
- No synergy when dosed simultaneously; useful as circadian bookends (Semax AM, DSIP PM) for sleep-wake optimization
- Thymosin Alpha-1
- Immune modulation, T-cell maturation, cytokine balance
- Synergistic. Overlapping cytokine suppression
- Both reduce IL-1β and IL-6; combined use addresses immune-mediated sleep disruption more completely
- No contraindication; monitor immune panels in immunocompromised models
- Strong synergy in inflammatory insomnia models; TA-1 addresses systemic immune dysfunction, DSIP targets CNS inflammation
- BPC-157
- Tissue healing, angiogenesis, anti-inflammatory
- Complementary. DSIP's endorphin release pairs with BPC-157's direct healing signals
- DSIP's beta-endorphin elevation + BPC-157's anti-inflammatory action = enhanced recovery in injury models
- No contraindication; both peptides lower inflammation through different pathways
- Recommended combination for recovery-focused research; non-overlapping mechanisms prevent receptor saturation
- CJC-1295 / Ipamorelin
- Growth hormone secretagogue, GH pulse amplification
- Neutral to mildly synergistic
- GH pulses occur during deep sleep; DSIP-enhanced slow-wave sleep may increase GH secretion window
- No direct contraindication; dose GH secretagogues before DSIP to align GH pulse with enhanced sleep depth
- Minor synergy; DSIP improves sleep quality during GH pulse window but doesn't directly amplify GH secretion
