Built for the hours after dark.
Kestran makes one thing: a daily men's formula for healthy prostate function, steadier flow and fewer occasional nighttime trips — made the way we'd want it made for our own fathers.*
This category taught men to expect actors in lab coats, hidden doses and subscriptions they couldn't cancel. We started Kestran to do the opposite, on every point.
The night is the product.
Nobody wakes up wanting a healthier prostate. Men want to sleep through to the alarm, take the long drive without mapping rest stops, and stop waking the person next to them. That's what we build for.
When we read the research, the gap was obvious. Nighttime trips often have two causes — how well the bladder drains, and how fast it refills overnight — yet almost every product on the shelf is aimed at the first one, built on an ingredient that failed the largest trials run on it, and dosed however the label allows.
So we built Kestran around three rules: only ingredients with human research behind them, at the amounts that research used; every dose printed on the label; and a lab report for every batch that anyone can look up.
Four promises.
Doses on the record
Every ingredient at an amount used in published human research, with the citation on our science page.
Tested, every batch
Independent testing for identity, potency and contaminants. Scan your bottle to see the report.
Real people only
No actors, no borrowed logos, no invented doctors. If we quote someone, they're real.
Fair subscriptions
A reminder before every shipment. Skip, pause or cancel with one text or email.
A complement to care, never a replacement.
We won't tell you to quit a prescription or skip a screening. Bring our label to your appointment — every dose is on it — and decide together.
Count your nights for 90 days.
You have a full 90 days to try Kestran. If you're not completely satisfied, just send us a quick message and we'll gladly refund your money.
Get ahead of it. Not after it.
Start while it's one trip a night, not four. Five studied ingredients, one capsule morning and evening, and 90 days to be sure.
