How it works

From questionnaire to ready-when-you-need-it.

A 2-minute questionnaire, private physician review, and propranolol shipped to keep on hand for whenever the moment arrives. No appointments, no in-person visit.

Step 1

2-minute questionnaire

A few questions about your health, current medications, and what you need propranolol for. Done from your phone, on your time.

Step 2

Private physician review

A licensed US physician reviews your case and confirms propranolol is appropriate. If they have questions, they'll message you. Most reviews complete within 1 business day.

Step 3

Discreet delivery

Propranolol ships in plain, unmarked packaging. Arrives in 3 to 5 business days. Keep the bottle on hand for whenever you need it.

Step 4

One tablet, 60 to 90 minutes before

Take a tablet when you have something coming up. Onset is 30 to 60 minutes, peak effect at 60 to 90 minutes, lasts 3 to 4 hours. No daily dosing, no buildup.

Doses available

Everyone starts at 10mg. 20mg if 10mg was not enough.

Propranolol for performance anxiety comes in four doses. 10mg and 20mg are self-serve through the questionnaire. 40mg and 80mg need more clinical tailoring and are available with membership. All work the same way: one tablet before the event, only when you need it.

10 mg as needed

Gentlest effective dose · take 60 to 90 min before the event

20 mg as needed

Already tried 10mg and need a stronger effect?

Higher as-needed doses benefit from more clinical tailoring, so we pair them with membership and physician follow-up. 10mg and 20mg are offered self-serve because they share the same safety profile and the same simple before-the-event routine.
About the medication

One small tablet. Your body stays out of your way.

Take one tablet 60 to 90 minutes before the moment. Propranolol blocks adrenaline at the heart and the body, so the stress response cannot show up.

  • One small tablet, before the momentNo daily dosing. Take it only when you have something coming up. With or without food.
  • Blocks the physical, not the mentalPropranolol blocks the receptors that adrenaline uses to speed up your heart and trigger tremor. The racing heart, shaky hands, sweating, and dry mouth never get going. Your thinking stays clear.
  • 3 to 4 hours of coverageEffects start in 30 to 60 minutes, peak at 60 to 90 minutes, and wear off over 3 to 4 hours. Long enough for a presentation, a performance, or a difficult conversation.
  • Non-sedating, non-habit-formingUnlike benzodiazepines, propranolol does not impair memory, cause sedation, or create physical dependence with occasional use.
Why propranolol

The original performance medication.

Propranolol has been used off-label for performance anxiety since 1982, when a landmark double-blind trial in musicians showed it eliminated the physical impediments to performance and improved how performers were rated by critics.

  • Blocks the body, not the mindPropranolol works on the body, not the brain. It blocks adrenaline where it lands in the heart, muscles, and sweat glands, so the tremor, racing heart, dry mouth, and sweating never get going. Your thinking stays clear so you can react on your feet.
  • Non-sedating, non-addictiveUnlike benzodiazepines (Xanax, Ativan), propranolol does not cause sedation, memory impairment, or physical dependence. You perform clearly and stop using it whenever you want.
  • Works in one dose, not over weeksSSRIs take 4 to 6 weeks to reach full effect. Propranolol works on the first dose. For event-based anxiety where you know exactly when the moment is, that is what you want.
Real results

What propranolol looks like in practice.

Three Instalab patients in their own words. Composites based on real patient experiences.

First audition

Steady hands when it counted

My bow hand used to shake the moment I sat down. With 10mg an hour before, the tremor never started. I could actually play the music I had been practicing.

Quarterly review

Sounded like himself, on the first try

I do not get nervous in the meeting room. I get nervous walking to it. Heart pounding, voice tight. One tablet 90 minutes before and that physical loop never starts. I sound like myself.

Executive, board presentations
One-time event

Present for the moment

I tested 10mg the weekend before to see how my body would feel. On the day, I took one 90 minutes before the toast. No shaking, no voice cracks. I actually got to be present.

Propranolol is a prescription medicine. Use for performance anxiety is off-label. Do not take propranolol if you have asthma, severe heart conditions, or a very slow heart rate. Common side effects include dizziness, fatigue, and cold hands or feet.
