Best Peptides for Sleep: Full Stack and Doses 2026
DSIP + Tesamorelin + GHK-Cu: three peptides targeting different layers of overnight recovery. DSIP induces deep sleep, Tesamorelin pulses growth hormone into the sleep window, GHK-Cu drives overnight cellular repair.
Why These Three Peptides
DSIP — Sleep Induction
Delta Sleep Inducing Peptide. A 9-amino-acid peptide that promotes slow-wave (delta) sleep, the deepest and most restorative stage. Shortens sleep latency, increases time in deep sleep, and reduces nighttime awakenings in most users.
Best for: Sleep onset, deep sleep duration
Route: Subcutaneous, 30–60min pre-sleep
Tesamorelin — GH Pulse
A GHRH analog. Triggers a natural growth hormone pulse from the pituitary. Dosed at bedtime, it aligns with the natural sleep GH peak and reinforces slow-wave sleep, where most overnight recovery and repair happens.
Best for: Deep sleep GH pulse, body composition
Route: Subcutaneous, at bedtime
GHK-Cu — Overnight Repair
Copper tripeptide. Drives overnight cellular repair through cytokine modulation, antioxidant pathways, and connective tissue regeneration. The repair component of the stack, working in parallel with the GH pulse.
Best for: Overnight tissue repair, recovery
Route: Subcutaneous, evening dose
Complementary Synergy: DSIP gets you into deep sleep. Tesamorelin maximizes the GH pulse during that sleep. GHK-Cu makes the most of the repair window. Each peptide targets a different layer of the same overnight recovery process.
Dosing Protocol
| Peptide | Dose | Frequency | Timing | Duration |
|---|---|---|---|---|
| DSIP | 100–500mcg | 5 nights/week | 30–60min pre-sleep | 4–8 weeks |
| Tesamorelin | 1–2mg | Daily | At bedtime | 8 weeks on, 4 off |
| GHK-Cu | 1–2mg | Daily | Evening, separate from Tesamorelin | 4–8 weeks |
Inject DSIP and Tesamorelin at different sites if dosed at the same time window. GHK-Cu can be timed earlier in the evening (8–9pm) since it does not need to align with sleep onset.
Stack Variations by Goal
Sleep onset insomnia
DSIP (primary)
Short cycles, dose 60 minutes pre-sleep. Tesamorelin and GHK-Cu are optional additions if recovery is also a goal.
Sleep maintenance (waking at 3am)
DSIP + low-dose Tesamorelin
Tesamorelin GH pulse helps sustain deep sleep mid-cycle. Avoid high doses that can cause early waking.
Athletic recovery during heavy training
Full stack
The most common application. Combines deep sleep induction with overnight repair drivers.
Body composition + sleep
Tesamorelin (primary) + DSIP
Tesamorelin lead for the GH pulse and visceral fat reduction. DSIP supports the sleep environment.
Jet lag / shift work
DSIP only, short cycle
5–10 day acute use. No need for the full stack on short cycles.
Stress-driven poor sleep
DSIP + Selank (evening)
Add Selank from the Cognitive Stack for stress modulation. Skip Tesamorelin if anxiety is the primary driver.
Sleep Response Timeline
DSIP effects are usually felt by night 2. Most users report falling asleep faster and reaching deep sleep earlier. Tesamorelin pulse adds to slow-wave duration.
Sleep architecture starts to consolidate. Time-in-deep-sleep increases on wearables. GHK-Cu overnight repair effects begin to show in skin and recovery quality.
Most users hit their sleep baseline by week 2. Morning HRV typically improves. Daytime energy stabilizes if other inputs (caffeine, screen time) are managed.
Plateau. Continue as needed. Most users find DSIP can be cycled (5 nights on, 2 off) without losing effect. Tesamorelin protocols often run 8 weeks before a break.
Critical Points
Glucose & Cancer Caution:Tesamorelin elevates IGF-1 through GH release. Those with diabetes, active cancer, or cancer history should avoid Tesamorelin entirely and consider a DSIP-only sleep protocol. GHK-Cu has copper as a component, so chronic high doses are not recommended for those with Wilson's disease.
