Sleep depth, slow-wave & recovery quality
One of 4 mechanistic pathways to 🌙 Sleep better · 10 options
Slow-wave sleep is when the largest GH pulse of the day happens and when the glymphatic system clears metabolic waste from the brain. Sleeping eight hours and feeling unrecovered is usually a depth problem, and almost nothing marketed for sleep improves it.
Eight hours and still unrecovered is a depth problem. Low IGF-1 and low morning testosterone are downstream evidence of it, since both are produced largely during slow-wave sleep.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
💉 Ipamorelin
Dosed at bedtime, the induced GH pulse stacks onto the natural nocturnal one. Users consistently report deeper sleep, which is plausible given ghrelin-receptor involvement in sleep architecture — and it is not what the compound was studied for.
💉 CJC No Dac/Ipamorelin
The larger combined pulse, same timing argument.
💉 Sermorelin
GHRH itself promotes slow-wave sleep in human studies — this is one of the few GH-axis sleep claims with direct human support.
💉 MK-677
Trials show increased slow-wave sleep and REM. It also raises appetite and fasting glucose, so the sleep benefit arrives attached to a metabolic cost.
🧬 Glycine
Improves subjective sleep quality and reduces next-day fatigue in trials — the effect appears to be on quality rather than duration.
🧬 Magnesium
Trials in older adults show increased slow-wave sleep and reduced cortisol.
🧬 Reishi
Traditional use for sleep depth; rodent work shows increased non-REM. Human trials are thin.
🧬 Ashwagandha
Improves sleep quality scores in RCTs, plausibly by lowering the nocturnal cortisol that fragments sleep.
🧬 L-Tryptophan
Serotonin substrate for the architecture itself, not just onset.
🧬 Zinc
Zinc status correlates with sleep quality, and it is a cofactor for melatonin synthesis.

Frequently asked questions
Slow-wave sleep is when the largest GH pulse of the day happens and when the glymphatic system clears metabolic waste from the brain. Sleeping eight hours and feeling unrecovered is usually a depth problem, and almost nothing marketed for sleep improves it.
10 options are mapped to this pathway in the Vault, including Ipamorelin, CJC No Dac/Ipamorelin, Sermorelin, MK-677. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 6 carry clinical validation and 3 are mechanistic predictions.
Eight hours and still unrecovered is a depth problem. Low IGF-1 and low morning testosterone are downstream evidence of it, since both are produced largely during slow-wave sleep. The markers worth checking are IGF-1 (Insulin-like Growth Factor 1), Total Testosterone, Cortisol (AM), Ferritin.
Unproven is not the same as ineffective. Of the 10 options on this pathway, 6 have clinical validation and 3 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
