How it works

It starts with one test. Then so much more.

From “something’s off” to dialed-in, in four steps.

Appointment confirmed notification over a man's arm at home — baseline lab testing scheduled with Keen1

Test your baseline

One simple lab draw — total T, free T, estradiol, PSA, hematocrit. At home or at a local lab.

The timeline

How long until your first bottle

It comes down to one thing: whether you already have recent testosterone labs. Pick your situation.

Prescription by day 8 or 9

  1. Day 1

    Intake, and your kit ships

    You fill in your history and pick your plan — one month or three. Your at-home blood kit goes out the same day, with tracking.

  2. Day 3

    It arrives, you send it back

    No lab visit and no waiting room. Posting it back is the step everything else waits on.

  3. Day 5

    Your telehealth visit

    Your results are read and a US-licensed provider takes you through what they show and what your options are.

  4. Day 8–9

    Your spray arrives

    If therapy is right for you, your script goes to the pharmacy and your first bottle reaches your door. Tracking follows it.

Typical timings, not a promise. Whether therapy is right for you is your provider's decision, so the last step is always conditional.

Member stories

Changing how men feel, across the country.

Most men feel the difference within the first few months. Individual results vary.

Keen member Marcus, 38, seated on a mustard velvet sofa in a bright sunlit room, looking to camera
Marcus, 38
I was doing everything I could to improve my health, but I still felt tired and unmotivated. I didn't want injections, so finding another treatment option finally gave me something that worked for me.

His doctor felt his low-end testosterone level was still acceptable.

Keen member Tyler, 42, seated on a mustard velvet sofa in a bright sunlit room, looking up toward the window
Tyler, 42
I thought being exhausted every afternoon was just part of getting older. Getting tested helped me understand what was actually going on and find a treatment that fit my needs.

He had been told the fatigue was simply part of getting older.

Keen member Jason, 45, relaxed on a mustard velvet sofa in a bright sunlit room, glancing across the room
Jason, 45
My workouts weren't the same, my recovery was slower, and I had lost a lot of my drive. Keen made it easy to get tested and finally talk to someone who took those changes seriously.

His symptoms had previously been blamed on stress and a busy schedule.

Keen member Daniel, 36, leaning forward on a mustard velvet sofa in a bright sunlit room, warm smile to camera
Daniel, 36
I knew something felt off, but I kept putting off treatment because I didn't want to give myself injections. Finding a needle-free option made it much easier for me to finally do something about it.

He thought injections were his only treatment option.

Keen member Chris, 49, one arm along a mustard velvet sofa in a bright sunlit room, looking across the room
Chris, 49
My energy, focus, and drive had slowly disappeared, and I started thinking that was just my new normal. Keen helped me get evaluated and find an option that made sense for me.

Previous evaluations focused on the lab number, not how he was actually feeling.
