Think: The tone you'd use explaining something important to a friend over coffee. Informed, encouraging, and real. Masculine but accessible, think "guy you'd grab a beer with who also happens to know his stuff"
Energy and tone: Confident without arrogance; conversational and approachable, sounds like a trusted friend, not a salesperson; natural warmth with an athletic edge, think someone who takes care of themselves but isn't obsessed; grounded and matter-of-fact delivery, no "announcer voice"
Delivery style: Direct and clear, cuts through without being harsh; knows how to land a joke without forcing it; can handle medical terminology naturally (doesn't stumble over "sildenafil" or "apomorphine"); comfortable addressing sensitive topics with zero awkwardness.
Brand alignment: Sounds like someone who's dealt with this stuff personally and came out the other side; confident enough to be direct about ED, testosterone, or sexual health without being clinical or juvenile.
