GOOD QUESTIONS
A little more
to go on.
What does it taste like? Does it contain alcohol?
An earthy mushroom taste. Mµ contains pure grain alcohol and is 20–24% ABV. Adding it to a hot drink is not established as a way to make it alcohol-free.
How do subscriptions work?
Choose every month (20% saving), every 6 weeks or every 8 weeks (15% saving). Skip, pause or cancel before your next charge. No minimum. HK$30 Hong Kong delivery below HK$500 applies to single-bottle subscriptions.
Can I take it with medication?
If you take medication, are pregnant or breastfeeding, or manage a health condition, check with your doctor before use. Mµ is a food supplement, not a medicine.

THE RESEARCH, HONESTLY
What the studies found.
Human studies have examined focus and exercise performance, with mixed findings. The studies used capsules, not Mµ.
Lion's Mane · 2023 · 41 healthy adults, 18–45
For 28 days, people took 1.8g of Lion's Mane a day in capsules, or a placebo. An hour after the first dose, the Lion's Mane group was faster on a focus test. On day 29 they reported lower stress than the placebo group. The memory tests showed no benefit. A small pilot study.
Docherty, Doughty & Smith, Nutrients, 2023Cordyceps CS-4 · 2010 · 20 healthy adults, 50–75
For 12 weeks, people took CS-4 capsules, about 3g a day, or a placebo. The CS-4 group's exercise thresholds, a measure of how hard you can work before you start to tire, went up. The placebo group's didn't. Maximum fitness didn't change in either group. A small pilot study; 15 people finished.
Chen et al., Journal of Alternative and Complementary Medicine, 2010Mµ's amounts are printed as raw equivalent, so they can't be compared directly with these capsule doses. That's what the 30-day guarantee is for.
