For men on TRT · Melatonin-free
On TRT, Up at 3AM? Sleep Through It.
You started TRT and almost everything got better — energy, strength, the gym. Except one thing: now you wake at 3am, hot and wide awake, every night. Cooldown Nightcap is the melatonin-free nightly drink built for exactly that. Glycine helps your body cool down and stay down — so you sleep through and wake up sharp. No hormones. No melatonin. Won’t touch your protocol.
A cooling mattress is $2,500. Cooldown Nightcap is $2 a night.
Launch offer: your first order ships with both gifts free — a $77 value while our launch stock lasts.

🔬 3rd-Party Tested · ✓ GMP Certified · 🌿 Non-GMO
🌡Cools You DownGlycine 3,000mg — studied to lower core body temperature, the heat half of the 3am wake-up
💤Keeps You DownMagnesium glycinate eases tension & supports staying asleep through the night
🧠Wake Up SharpL-Theanine promotes calm focus, not sedation — no morning fog to dull your edge
⭐The Whole StackGlycine, mag glycinate, L-theanine, apigenin, saffron, GABA — dosed, in one drink
This is for you if…
✓You started TRT and your sleep got worse, not better
✓You wake at 2–4am hot, drenched, and wide awake
✓You’ve dialed your dose, E2, and labs — the sweats are still there
✓You refuse melatonin grogginess — you need to be sharp tomorrow
🌡
How it worksOn TRT, more testosterone aromatizes to estradiol — and estradiol shifts how your body manages heat (the same mechanism behind menopausal night sweats). Glycine works on the heat: it supports the natural core-temperature drop your body needs for deep sleep — without touching your hormones.→ Cooler core, fewer 3am wake-ups, and a clear head in the morning
Why melatonin-free matters
😵
Melatonin leaves you groggyMorning fog costs you the exact edge you optimized for — the opposite of waking up sharp.
🔁
It stops workingMany men find melatonin fades the longer they take it — and skipping a night gets harder.
✓
Cooldown Nightcap works differentlySupports your body's natural wind-down — no hormone override, no morning fog, no habit, no interaction with your protocol.
🔬Glycine clinical research: In a peer-reviewed study, participants taking 3g of Glycine before bed fell asleep up to 13 minutes faster and reported significantly better next-morning alertness vs. placebo.

What’s inside
Every ingredient earns its place.
No fillers. No proprietary blends. Every compound dosed for a reason.
01GlycineAmino acid studied for its role in sleep quality, bedtime comfort, and supporting a cooler, calmer wind-down. The most researched ingredient for hot sleepers.3,000 mgBedtime comfort
02Magnesium GlycinateThe most bioavailable form of magnesium. Supports muscle relaxation and is associated with improved sleep quality and duration.200 mgDeep sleep
03L-TheanineFound naturally in green tea, L-Theanine promotes alpha brain wave activity — a calm, alert state that transitions smoothly into sleep without sedation.200 mgCalm focus
04Affron® (Saffron extract)Patented saffron extract clinically studied for sleep quality improvements. Supports serotonin activity and reduces nighttime waking in peer-reviewed trials.28 mgSleep quality
05ApigeninA natural flavonoid found in chamomile. Binds to GABA-A receptors to produce a calming effect — without the dependence risk of pharmaceutical alternatives.50 mgRelaxation
Simple routine
One drink. 60 seconds.
No blender. No prep. Just add water and let the science do the work.
🥤
1
Add to Water
Pour one sachet into 8–10 oz of cold or room-temperature water. Hot water works too — it becomes a calming evening tea. Tastes like a crisp blackberry lemonade — lightly sweet, slightly tart, never medicinal.
⏱ 10 seconds
🌀
2
Stir & Drink
Give it a quick stir until dissolved. Drink it 30–60 minutes before bed — this gives glycine and L-theanine time to take effect.
🌙 30–60 min before bed

Wake Up Cool
You wind down more easily, sleep comes faster, and you stay there. Most customers notice a difference within the first 3–5 nights.
✓ Results in 3–5 nights
The science behind it
Why people who run hot rarely get truly restful sleep.
Sleep researchers have long studied the connection between running warm at bedtime and disrupted sleep quality. For people who run hot, that discomfort keeps you in lighter, more restless sleep — or pulls you awake at 3am.
🌡The problemYour body runs too warmFor people who run warm at bedtime, that heat keeps the nervous system alert rather than settling — making it harder to reach the deeper, more restorative stages of sleep.

⚗The formula5 compounds work togetherGlycine 3,000mg is studied for its role in supporting a cooler, calmer bedtime transition. L-Theanine supports nervous system calm. Affron® saffron is clinically studied to help reduce nighttime waking.

🌙The resultCool, deep, uninterrupted sleepYou fall asleep more easily, experience less nighttime restlessness, and wake feeling more rested — without the grogginess melatonin can leave behind.

Why I built this
I built this because I lived it.
"A couple years ago I started TRT. Almost everything got better — energy, strength, I felt like myself again. But within weeks I was waking up at 3am drenched, heart going, wide awake. Every night. I had my bloodwork done, ruled out apnea, dialed my estradiol, tried every sleep supplement on the shelf. Melatonin just left me foggy. Nothing kept me cool and asleep. So I built the drink I couldn't find — melatonin-free, made to cool you down and keep you down, without touching your protocol. If you run hot and wake at 3, I made this for us."

“Started TRT last year and the night sweats wrecked my sleep. Dialed my E2, tried everything. This is the first thing that actually kept me cool and asleep — and no fog in the morning.”
★★★★★
“I was stacking glycine, mag, and theanine separately and still guessing doses. This is all of it in one drink. I wake at 3 maybe once a week now instead of every single night.”
★★★★★
“40, training hard, run hot at night. Was about to drop $2k on a cooling mattress. Tried this first — resting HR down, recovery up, the 3am wake-ups are gone.”
★★★★★
“Everything improved when I got my health dialed in — except sleep. This fixed the one part nothing else would. The 3am wake-ups that were my normal for years just stopped.”
★★★★★
“Melatonin always knocked me out but I’d feel hungover all morning — useless when I need to be sharp. This doesn’t do that. I don’t feel it kick in, I just notice I slept through.”

Got questions?
Everything you need to know.
Most customers notice a difference within the first 3–5 nights. The full effect builds over 2–4 weeks as your body adapts. We recommend giving it at least 30 days for a fair assessment — that’s why we offer a money-back guarantee.
No. Cooldown Nightcap is non-hormonal and melatonin-free — glycine, magnesium glycinate, L-theanine, apigenin, Affron® saffron and GABA. Nothing in it touches testosterone, estradiol, or your protocol. As always, run any new supplement by your prescriber.
On TRT, some testosterone converts to estradiol, and estradiol changes how your body manages heat — the same mechanism behind menopausal night sweats. That heat keeps your core temperature from dropping enough to hold deep sleep, so you surface in the small hours. Glycine targets the heat by supporting your body’s natural core-temperature drop.
Melatonin regulates sleep timing, not temperature or sleep quality. For men who run hot, it doesn’t address the warmth that wakes you — and higher doses can leave you foggy in the morning, which costs you the edge. Our formula targets the heat and nervous-system calm instead, melatonin-free.
Yes. Every ingredient is non-habit-forming and safe for nightly use. Glycine, Magnesium Glycinate, L-Theanine, Apigenin, and Affron® are all well-studied compounds with strong safety profiles. Affron® is a standardized extract used in peer-reviewed clinical trials. Always consult your doctor if you have underlying conditions or take medications.
