Sleep

Research compounds studied for supporting growth hormone release during sleep, restoring circadian rhythm function, and improving sleep architecture and quality.

Most researched for Sleep

Ipamorelin

The most widely used entry point for sleep-focused GH protocols. Selectively stimulates a clean GH pulse via ghrelin receptors without meaningfully raising cortisol or prolactin - making it more precise than older GHRPs. When taken 30 minutes before sleep, the GH pulse aligns with natural slow-wave sleep cycles.

Ibutamoren

aka MK-677, MK-677, Nutrobal

Popular

How it works: Selectively binds GHSR-1a; stimulates pituitary GH and IGF-1; oral bioavailability; ~24h action

GH and IGF-1 elevation; muscle mass; recovery; sleep quality; anti-aging

Dosage range

10-25 mg, Once daily (oral)

Administration

Oral

Timing

Evening (aligns with GH pulse and sleep)

Cycle length

8–12 wks on; 4–8 wks off; long-term use debated

CJC-1295 (without DAC) / Modified GRF 1-29

aka CJC-1295 no DAC, Mod GRF 1-29, GHRH(1-29)

Popular

How it works: Extends and amplifies the GH pulse by stimulating GHRH receptors, combining with GHRPs for stronger GH release.

GH pulse stimulation (combined with GHRP); body recomposition; sleep; recovery

Dosage range

100-300 mcg, 1–3×/day (combined with GHRP)

Administration

SubQ

Timing

Pre-bed (15 min before sleep); or pre-workout; ALWAYS with GHRP

Cycle length

8–16 wks on; 4–6 wks off

Ipamorelin

aka NNC 26-0161

Popular

How it works: Selectively stimulates GH release via ghrelin receptors without raising cortisol or prolactin.

GH pulse stimulation; body recomposition; recovery; sleep quality

Dosage range

200-300 mcg, 1–3×/day (pre-bed most common)

Administration

SubQ / IM

Timing

Pre-bed; or pre-workout

Cycle length

8–12 wks on; 4 wks off

Sermorelin

aka GHRH(1-29)

Moderate

How it works: Binds pituitary GHRH receptor; stimulates natural pulsatile GH release; shorter half-life than modified GRF 1-29 analogs

GH stimulation; body composition; sleep; anti-aging (clinic use)

Dosage range

100-500 mcg, Once daily pre-bed

Administration

SubQ

Timing

Pre-bed on empty stomach

Cycle length

8–16 weeks

CJC-1295 with DAC

aka CJC-1295 DAC, Drug Affinity Complex CJC-1295

Moderate

How it works: Binds GHRH receptor; DAC linker covalently bonds to plasma albumin → ~6–8 day half-life; produces tonic GH elevation rather than physiological pulsatile release

Sustained GH/IGF-1 elevation; body composition; anti-aging; less frequent dosing

Dosage range

1-2 mg, Once or twice per week

Administration

SubQ

Timing

Any time (long half-life)

Cycle length

8–12 weeks

Epitalon

aka Epithalon, Epithalon, Ala-Glu-Asp-Gly

Moderate

How it works: Activates telomerase enzyme to support telomere length maintenance and stimulates pineal melatonin production.

Anti-aging; telomere elongation; circadian rhythm regulation

Dosage range

5-10 mg, Daily ×10–20 day cycle

Administration

SC / IM / Intranasal

Timing

AM or PM (no strong data)

Cycle length

10–20 days; 2× per year

Delta Sleep-Inducing Peptide

aka DSIP, DSIP, Emideltide, Delta sleep peptide

Moderate

How it works: A naturally occurring neuropeptide studied for its role in promoting slow-wave sleep onset.

Sleep induction; sleep quality improvement; delta wave enhancement

Dosage range

100-300 mcg, Once 30–60 min before bed

Administration

SubQ / IM

Timing

30–60 min before intended sleep

Cycle length

2–4 wks on; break

Sermorelin + Ipamorelin

aka Combo, Sermorelin + Ipamorelin Clinic Combination

Moderate

How it works: Sermorelin stimulates GHRH receptor; Ipamorelin stimulates ghrelin receptor; combined 2–3× GH pulse vs either alone; same mechanism as CJC-1295 no DAC + Ipa but uses Sermorelin (older GHRH analog)

GH axis optimization via two-compound synergistic protocol; body composition; sleep; anti-aging

Dosage range

200-300 mcg each, Pre-bed daily or 5 on/2 off

Administration

SubQ

Timing

Pre-bed 15–30 min; 2h fast preferred

Cycle length

8–16 wks on; 4–6 wks off

Epitalon Oral

aka Oral Epitalon, Oral Epithalon capsules

Moderate

How it works: Same mechanism as injectable Epitalon; small tetrapeptide may survive GI digestion partially; oral bioavailability claimed by manufacturers; FDA PCAC review (same compound)

Telomere support; circadian regulation; anti-aging — oral route convenience

Dosage range

20-30 mg, Daily (oral)

Administration

Oral

Timing

Morning

Cycle length

10–20 day course; 2× per year

Pinealon

aka EDR, Glu-Asp-Arg

Advanced

How it works: Binds DNA regions in brain/retinal cells; stimulates neuroprotective gene expression; anti-apoptotic; antioxidant in neural tissue; Khavinson bioregulator targeting brain involution

Cognitive aging protection; neuroprotection; sleep/circadian modulation

Dosage range

5-10 mg, Daily ×10 day course

Administration

SC / Intranasal

Timing

AM preferred

Cycle length

10 days; 2× per year

Example stacks

Beginner

Sleep - Beginner

Ipamorelin alone before bed is the most widely used and safest entry point. Clean GH pulse with minimal side effects, aligned with deep sleep cycles.

Primary
Ipamorelin200 mcg - 30 minutes before bed
  • Inject 30 minutes before sleep
  • Maintain a consistent sleep schedule
  • Eat your last meal 2+ hrs before injecting
Intermediate

Sleep - Intermediate

CJC-1295 extends and amplifies the GH pulse Ipamorelin initiates. The result is a deeper, longer GH release during sleep.

Primary
CJC-1295100 mcg - 30 minutes before bed
Primary
Ipamorelin200 mcg - 30 minutes before bed
  • Mix in the same syringe - no need for two injections
  • Run 5 days on, 2 days off
  • Track sleep quality with a wearable if possible
