Fearless, aware, and protected
HARNESS Adult Track
Science as your wingman. HARNESS teaches combination prevention as a modular system: five pieces you choose, fit together, and test against the messy situations real life actually throws at you.

The five pieces
No single method covers every situation. HARNESS helps adults pick the combination that fits their life, and keep it running.
Medications
PrEP, PEP, Doxy-PEP, and vaccines — what each does, when it applies, and how to ask for it.
Awareness
Testing rhythms, knowing your status and a partner's, and what U=U means.
Tools
The physical frontline: external and internal condoms, dental dams, gloves, and lube.
Communication
Consent, disclosure, and scripts for conversations that feel hard to start.
Habits
Refills, reminders, and routines that keep the plan working on a bad week.
Naming the Ghosts
Fear doesn't disappear when you ignore it. HARNESS treats each fear as data — name it, map it to a MATCH piece, and give it a task.
The plan stress test
A plan that works on a calm Tuesday can fall apart after two drinks or a surprise bill. Participants run their plan against eight scenarios and fix the weak points before they matter.

30-Day Fearless Challenge
Protection is a muscle. After the workshop, participants practice one small action a day for 30 days so the plan becomes routine instead of a one-time decision.
