GH-secretagogue peptides (CJC-1295, Ipamorelin, Tesamorelin, MK-677) work primarily during slow-wave sleep — that 25-90 minute window when 60-70% of the nightly GH pulse fires. Anything that increases slow-wave sleep depth amplifies the peptides' downstream effect. The premium sleep stack (Magtein, apigenin, L-theanine, glycine, reishi) targets the specific physiological pathways that govern slow-wave sleep architecture.
The 5 picks
1. Best foundational — Double Wood Magnesium L-Threonate (Magtein)
2,000 mg Magtein® per serving (144 mg elemental Mg). ~$30/month.
Magnesium L-Threonate is the only form that crosses the blood-brain barrier. The Stanford-patented Magtein® form increases brain magnesium specifically. Best evidence-backed sleep mineral.

2. Best apigenin — Double Wood Apigenin 50 mg
Apigenin extract. Chamomile-derived flavonoid. ~$25/month.
Apigenin binds GABA-A receptors and modestly increases slow-wave sleep. The Andrew Huberman-popularized supplement. Stack with magnesium L-threonate for synergistic effect.

3. Best L-theanine — Sports Research L-Theanine 200 mg
200 mg pure L-theanine per capsule. ~$15/month.
L-theanine promotes alpha brain wave activity and parasympathetic dominance. Take 200-400 mg 1-2 hours before bed.

4. Best glycine — NOW Foods Glycine Powder
3,000 mg glycine per scoop. ~$15/month.
Oral glycine 3 g pre-bed has published evidence for improved subjective sleep quality and slow-wave depth. Mix in water; mildly sweet taste.

5. Best mushroom — Real Mushrooms Reishi Extract
1,000 mg dual-extracted reishi. ~$30/month.
Reishi mushroom (Ganoderma lucidum) is the traditional sleep tonic. Real Mushrooms® uses both alcohol and water extraction for full spectrum compounds. Take 30-60 min before bed.

Frequently Asked Questions
When to take each component?
Magnesium L-Threonate: 30-60 min before bed. Apigenin: 30 min before bed. L-Theanine: 1-2 hours before bed. Glycine: 30 min before bed. Reishi: 60 min before bed.
Will this help with GH peptide results?
Indirectly yes — deeper slow-wave sleep is when 60-70% of nightly GH fires. Amplifying slow-wave sleep amplifies the peptides' effect on IGF-1 and recovery.
Can I stack all 5?
Yes — they target different mechanisms (GABA, parasympathetic shift, brain magnesium, glycine receptors). Start with 2 (Magtein + glycine) for 2 weeks; add others if needed.
Will I be groggy in the morning?
Most users report waking more refreshed, not groggy. If grogginess occurs: reduce L-theanine dose first, then glycine.
Safe with my GLP-1?
Yes — no interaction with semaglutide, tirzepatide, or retatrutide. Take with light snack if you experience GI sensitivity from supplements on an empty stomach.
How long until results?
Sleep onset improvement: 1-2 weeks. Slow-wave sleep depth (visible on Oura/Whoop): 2-4 weeks. Cumulative GH peptide benefit: 4-8 weeks.
