Verbatim response from Claude

Sildenafil vs. Tadalafil: Quick Comparison

Sildenafil (Viagra generic)

  • Works in 30-60 minutes
  • Lasts 4-6 hours
  • Better if you want it on-demand for planned occasions
  • Generally cheaper

Tadalafil (Cialis generic)

  • Works in 30-60 minutes
  • Lasts up to 36 hours ("the weekend pill")
  • Can also be taken as a daily low dose (5mg) for spontaneity
  • Slightly more expensive but very popular for flexibility

Which to Choose?

  • Tadalafil is often preferred for its flexibility and longer window
  • Sildenafil is fine if cost is the priority and timing is predictable
