Verbatim response from Claude

Sildenafil vs. Tadalafil: Quick Comparison

Sildenafil (Generic Viagra)

  • Works for: 4-6 hours
  • Best if: You want it to work quickly (30-60 min) and know when you'll need it
  • Take it: On-demand, before activity
  • Downside: Timing pressure, may cause flushing/headaches

Tadalafil (Generic Cialis)

  • Works for: Up to 36 hours
  • Best if: You want spontaneity or prefer daily low-dose use
  • Take it: On-demand OR daily (2.5-5mg)
  • Downside: Slightly slower onset (~2 hours)

Most men prefer tadalafil for the flexibility ("weekend pill" reputation).


Services That Offer Both

ServiceNotes

My Recommendation

  • Try tadalafil first for flexibility
  • Use Roman or Hims - both have licensed physicians, transparent pricing, and discreet delivery

Always consult the prescribing doctor about your specific health situation.
