- Primary Action
- Modulate neurotransmitter balance (GABA, orexin) and hormone pathways without receptor antagonism
- Force sleep through GABA-A receptor agonism or orexin receptor blockade
- Signal circadian phase shift; minimal direct sleep-inducing effect
- Peptides support natural architecture; pharmaceuticals override it
- Deep Sleep Impact
- Increase slow-wave sleep duration 15–30% with no REM suppression
- Suppress REM sleep; increase light sleep but reduce restorative stages
- No measurable effect on sleep architecture in most studies
- Only peptides and some natural compounds meaningfully increase deep sleep
- Tolerance Development
- Minimal to none over 12-week cycles
- Develops within 2–4 weeks; efficacy declines 40–60%
- No tolerance but also no sustained efficacy beyond circadian signalling
- Peptides maintain effect; pharmaceuticals lose efficacy rapidly
- Next-Day Effects
- No grogginess; cognitive function unaffected
- Residual sedation in 30–50% of users; impaired morning cognition
- Generally none unless dose exceeds 3mg
- Pharmaceuticals carry functional cost; peptides don't
- Dependency Risk
- None documented in clinical trials
- Physical and psychological dependence common with nightly use
- None
- Long-term pharmaceutical use creates withdrawal insomnia
