Sleep Architecture Protocol
Nighttime GH-axis stack for deeper slow-wave sleep — CJC-1295 + Ipamorelin nightly, with DSIP as an optional sleep-onset adjunct.
TL;DR
Inject 100 mcg CJC-1295 (no-DAC) + 100 mcg Ipamorelin subcutaneously, 5 nights per week, 15–30 minutes before bed. The dual-mechanism GH pulse drives deeper slow-wave sleep within 2–3 weeks. DSIP at 100–300 mcg is an optional adjunct for sleep onset, not deep-sleep maintenance.

Who this protocol is for
- Adults with poor subjective sleep quality despite adequate sleep duration
- Athletes seeking recovery optimization via slow-wave sleep enhancement
- Aging populations with diminished natural GH pulse + reduced SWS
- Post-injury recovery where deep sleep matters for tissue repair
- Practitioners running body-recomposition protocols who want the sleep + GH axis effect
Why this stack
The natural GH pulse during slow-wave sleep is the largest GH release of the day. Boosting that pulse with a GHRH analog (CJC-1295) + a ghrelin-receptor agonist (Ipamorelin) produces a larger, longer pulse than either component alone — and crucially, the larger pulse appears to feed back into deeper slow-wave sleep, creating a positive cycle.
Ipamorelin specifically (rather than older GHRPs like GHRP-2 or GHRP-6) is the right choice for sleep protocols because it's selective for GH release with minimal cortisol or prolactin spillover. The older GHRPs raise cortisol meaningfully, which is exactly what you don't want before sleep.
DSIP is a different category. It's a delta-sleep-inducing peptide that influences sleep onset more than sleep architecture. It's useful as an adjunct when sleep onset is the bottleneck, but it's not a substitute for the GH stack when deep-sleep maintenance is the goal.
Phase schedule
Phase 1
Weeks 1–4: Initiation
Standard nightly dosing of the CJC + Ipamorelin stack. Sleep changes typically begin within 1–2 weeks; full effect on slow-wave sleep architecture takes 3–4 weeks.
- CJC-1295 (no-DAC): 100 mcg subQ, 5 nights/week.
- Ipamorelin: 100 mcg subQ, 5 nights/week (same injection).
- Optional DSIP: 100–300 mcg subQ, 30 min before bed if sleep onset is the primary issue.
- Timing: 15–30 min before lights-out.
Phase 2
Weeks 5–12: Maintenance
Continue at the same dose. Track sleep quality with a wearable (Oura, Whoop, Apple Watch) for objective slow-wave + REM minutes. Most users see slow-wave sleep gains of 15–30%.
- Same nightly dosing as initiation phase.
- Track: SWS minutes, sleep efficiency, total deep + REM.
- Adjust: if morning grogginess persists, drop Ipamorelin to 50 mcg.
Phase 3
Weeks 13–16: Off-cycle
Stop both peptides for 4 weeks. Receptor desensitization is the primary reason for cycling — uninterrupted use blunts the GH pulse over time. Track sleep during the wash to see if gains persist.
- No injections for 4 weeks.
- Track sleep metrics throughout — some users keep most gains.
- Resume: identical 8–12 week cycle if effects faded.
Step-by-step setup
- Source pharmaceutical-grade peptides. CJC-1295 and Ipamorelin are often co-vialed by compounders. If buying separately, verify HPLC/mass-spec results. Janoshik testing is the practitioner standard for raw vial verification.
- Reconstitute the stack. Standard reconstitution: 2 mL bacteriostatic water into a 5 mg vial of each → 2.5 mg/mL. On a 100-unit insulin syringe, 4 units = 100 mcg. If using a pre-mixed combo vial, follow the supplier's specific reconstitution instructions.
- Inject 15–30 minutes before bed. Subcutaneous in the abdomen. The GH-pulse window is 30–60 minutes post-injection — you want that pulse aligned with your sleep onset, not before it. Earlier injection wastes the pulse on wake-hours.
- Skip food for 90 minutes pre-injection. GH release is suppressed by elevated insulin and circulating glucose. Inject in a fasted or low-insulin state — finish dinner ≥90 minutes before bedtime injection.
- Track baseline + weekly sleep architecture. Use a wearable for SWS and REM minutes. Baseline 2 weeks before starting. Compare weekly during the protocol. The most reliable marker is slow-wave sleep minutes per night.
- Add DSIP only if onset is the bottleneck. DSIP helps initiate sleep — it doesn't deepen sleep architecture the way the GH stack does. Add 100–300 mcg DSIP 30 min before bed if you have sleep-onset insomnia but normal deep sleep when you finally fall asleep.
- Pair with sleep hygiene. Peptides amplify good sleep architecture; they don't override bad sleep hygiene. Cool room, dark room, consistent wake time, no late caffeine, no late alcohol. The combination outperforms either alone.
Expected outcomes
- Slow-wave sleep increase of 15–30% by week 4 (wearable-measured)
- Improved subjective sleep quality and morning recovery scores
- Modest IGF-1 elevation (10–20% above baseline) as a side benefit
- Improved body composition in some users (lean-mass-favorable GH effect)
- Reduced perceived fatigue and improved daytime cognitive performance
Safety + side-effect profile
The CJC + Ipamorelin stack has a favorable safety profile compared to exogenous HGH because it works through the body's own pulsatile system. Ipamorelin's selectivity (low cortisol/prolactin spillover) is part of why it's the preferred GHRP for this protocol.
- Morning grogginess can occur in the first 1–2 weeks — usually resolves as the body adjusts.
- Numbness or tingling in extremities at higher doses — drop dose if persistent.
- Water retention: occasional and mild; usually resolves within 2 weeks.
- Mild rise in fasting glucose — monitor if you have prediabetes or T2D.
- Increased appetite from ghrelin-receptor agonism (Ipamorelin) — manage with timing.
- Avoid during active malignancy — both increase IGF-1 signaling.
- Cycle 8–12 weeks on / 4 weeks off — receptor desensitization with continuous use.
- Not appropriate during pregnancy or breastfeeding.
Frequently asked
Will this protocol help me fall asleep faster?
Not primarily. The CJC + Ipamorelin stack improves slow-wave sleep maintenance — once you're asleep, sleep is deeper. If sleep onset is your main issue, DSIP (100–300 mcg) is the better fit. Many users run both: DSIP for onset, CJC+Ipa for depth.
Can I take this every night, or do I need to cycle?
Practitioner consensus is 5 nights on / 2 nights off weekly, with an 8–12 week cycle followed by a 4-week break. Continuous nightly use blunts the GH-pulse response over time (receptor desensitization). The cycling pattern preserves effectiveness.
What's the difference between CJC-1295 with DAC and without?
CJC-1295 'no-DAC' (also called Mod GRF 1-29) has a ~30-minute half-life — it produces a clean nighttime pulse. The DAC version has a 7-day half-life because it binds to serum albumin — it produces a sustained GH elevation rather than a pulse. For sleep protocols, no-DAC is the right choice. DAC is used for different goals.
Do I have to inject before bed, or any time at night?
Inject 15–30 minutes before bed. The GH-pulse window is 30–60 minutes post-injection. You want that pulse aligned with sleep onset — too early and the pulse happens while you're still awake; too late and you may have trouble falling asleep with the pulse priming you.
Why does eating before injection matter?
GH release is suppressed by elevated insulin and circulating glucose. If you inject 30 minutes after a big meal, the resulting GH pulse is significantly smaller. Practitioner protocols recommend a 90-minute pre-injection food-free window for the cleanest pulse.
