"Will I gas out anyway?"
★★★★★
I take it before open mat and it lets me roll round after round without getting gassed. It doesn't spike my heart rate or make me crash like energy drinks do.
MYDOS PERFORMANCE

Gassing out by round four?
Keep Up At Open Mat.
Mydos is a small caffeine-free shot made from cordyceps mushroom. It helps your muscles make and use energy, so you've still got something left when the room doesn't.

What changes on the mat.
You don't need more energy at the start of class. You need it at the end.
Finish open mat without the round-four cliff.
3,000 mg of cordyceps supports how your muscles rebuild energy and use oxygen, so output fades slowly instead of falling off a wall.
No caffeine crash on the drive home.
Zero caffeine means there's nothing to wear off. Your heart rate goes where the rolling puts it, not where a stimulant puts it.
Nothing between you and sleep after a late class.
No stimulants, so there's no half-life to wait out. Take it before an 8 pm class and there's no caffeine keeping you up afterward.
One shot. No scoop, no shaker.
60 ml, no sugar, lives in the gym bag. Drink it in the parking lot and walk in.
What your pre-workout is actually doing.
Caffeine masks fatigue. Cordyceps builds capacity.
Caffeine blocks the signal that tells you you're getting tired. It doesn't change how much fuel your muscles have. So you push harder than your recovery can cover, and you pay for it in the next session. It also doesn't leave when class does. A pre-workout at 6:30 is still more than half there when you lie down at 11.
Cordyceps works on the other line: how much energy your cells can rebuild, and how well they use oxygen. Nothing borrowed, nothing due after class. Studies are linked in the comparison table below.
Modelled on a 5-hour average half-life. Your number depends on genetics; the usual range is roughly 3 to 7 hours. In a controlled trial, 400 mg six hours before bed cut measured sleep by over an hour, and most people didn't notice. Drake et al., J Clin Sleep Med 2013.
What to expect, and when.
Caffeine is felt in ten minutes. Cordyceps takes weeks. If you judge Mydos by the first bottle, you're testing the wrong thing.
-
First session
Mostly what you don't feel.
None of what caffeine does: no jitters, no spiked heart rate, no slump in the car, no lying awake after a late class. Some people feel steadier on day one, but that's not the main thing working yet.
-
Weeks 1 to 3
The part where people quit.
This is where cordyceps does its work, inside your cells, slowly. There's nothing dramatic to feel. Keep taking one before every class. A case at three or four sessions a week covers this stretch almost exactly.
-
Weeks 3 to 6
Where the difference shows up.
What customers describe: getting through open mat without the round-four drop, and rolling the last round close to the pace of the first. Sleep and training load still matter. This isn't magic.
Does it actually hold up in a hard roll?
Three people who train, answering the questions you're probably asking.
"I train late. What about sleep?"
★★★★★
I take it before late open mats and feel locked in the whole session. Best of all, it does not mess with my sleep afterwards.
"Is this just caffeine in disguise?"
★★★★★
Coffee and energy drinks make me feel like I'm having a heart attack when I train. With Mydos I feel steady and focused, all without unwanted side effects.

Including doing nothing. Caffeine wins on two rows, and that's fine. Pick what fits your class time.

Caffeine ranges are typical retail products. Coffee is cheap and fast and there's nothing wrong with it before a morning class. The problem is the 7 pm class and the round you don't have.

Before you buy.
Will it make me jittery or spike my heart rate when I'm rolling?
No. There's no caffeine and no stimulant of any kind in it, so there's nothing to push your heart rate up. Cordyceps works on how your cells make energy, not on your nerves. People describe the opposite of a stimulant: calm and steady, not amped.
I train at 7 or 8 pm. Will it wreck my sleep?
It shouldn't. Caffeine lasts five to six hours in your body, which is why a 6:30 pm pre-workout is still going at midnight. Mydos has nothing that lingers like that. Kameron's review above is about exactly this.
Is this just caffeine wearing a mushroom costume?
No. The label lists every ingredient by amount: cordyceps, rhodiola, vitamin B12, tart cherry, monk fruit, vitamin C, and preservatives. No guarana, no yerba mate, no green tea extract, no other caffeine source hiding under a different name.
I didn't feel much from the first bottle. Did I waste $48?
Not yet. Caffeine hits a receptor, so you feel it in minutes. Cordyceps changes how your cells make energy, and that builds over weeks of taking it before training. The first bottle mostly shows you what's missing: the spike, the crash, the bad sleep. Judge it at the end of the case. If you still don't see it in round five, ask for your money back.
$4 a session. Is that worth it?
Compare it to what you're already spending. In a 2026 survey of 1,000 U.S. coffee drinkers, about 1 in 4 people who buy from coffee shops spend more than $20 a month at the counter, and 13% spend over $30, before counting what they brew at home. If you're one of the 7% buying a coffee every day at $4, that's roughly $120 a month on something you don't take before training. Drive Research, 2026.
Mydos on subscription is $38 a month for twelve shots, about $3.17 each, taken only on the days you train. And if your late rounds look the same at the end of the case, you get the $38 back.
Skipped to the bottom? Here's the pitch.
- A caffeine-free cordyceps shot. One before training.
- Caffeine masks fatigue. Mydos builds capacity. No caffeine, so no caffeine crash, no heart-rate spike, nothing keeping you up.
- Takes a few weeks to show up. One case covers that window.
- Don't see it by the end of the case? Full refund, no questions.
