If you train hard and sleep poorly, you're spending money on supplements that can't do their job. Every recovery process you care about — protein synthesis, glycogen restoration, growth hormone release, central-nervous-system reset — happens primarily during sleep, and primarily during the deep and REM stages.
Most sleep aids attack the wrong problem. They optimize for falling asleep fast. We optimized for falling asleep fast, sleeping more deeply, and waking up rebuilt — three different problems that need three different ingredients.
Why no melatonin
Melatonin is the default sleep ingredient because it's cheap and it works for jet-lag and shift-work scenarios where you're trying to reset a misaligned circadian rhythm. For an adult who is already sleeping at the same hour every night, supplemental melatonin is mostly downside: groggy mornings, vivid dreams, blunted natural production over time, and at the doses commonly sold (3–10mg), pharmacological levels that the body never produces on its own.
If you want a sleep stack you can take every night for years without the body adapting against you, melatonin is the wrong base.
The actual stack
- 01Glycine, 3g — shortens sleep-onset time and increases the proportion of slow-wave sleep. Acts on the SCN (your master clock) without overriding it.
- 02Magnesium glycinate, 300mg — bound to glycine for clean absorption, no GI distress.
- 03L-theanine, 200mg — relaxes without sedation, takes the edge off pre-bed cortisol.
- 04Apigenin, 50mg — flavonoid found in chamomile, binds to GABA-A receptors gently, lowers night-time cortisol.
- 05L-tryptophan, 500mg — serotonin precursor, supports endogenous melatonin production rather than replacing it.
“We made the supplement we'd take for the next thirty years, not for the next thirty nights.”
What you should expect
About thirty minutes after taking SLEEP you'll feel a quiet, deflated edge — not drowsy, just calm. Sleep-onset typically drops by 15-20 minutes for most people. Deep-sleep percentage goes up enough that wearables (Whoop, Oura, Garmin) reflect it within a week.
What you shouldn't expect: knockout sedation. SLEEP is a tuning, not a sledgehammer. If you're chronically under-sleeping because of stress or schedule, no capsule fixes that. You still have to leave the gym, close the laptop, and go to bed.
