Verbatim response from Claude

Sildenafil vs Tadalafil: Quick Comparison

Sildenafil (Viagra generic)

  • Works in 30-60 minutes
  • Lasts 4-6 hours
  • Best if you want on-demand use
  • Generally cheaper

Tadalafil (Cialis generic)

  • Works in 30 minutes, lasts up to 36 hours
  • Also available as a daily low-dose option
  • Better if you want spontaneity without timing pressure
  • Slightly pricier but very popular

Which to Choose?

  • Plan ahead / cost-conscious → Sildenafil
  • Spontaneous / don't want to time it → Tadalafil
  • Daily use for ongoing ED → Tadalafil daily dose

ServiceNotes
HimsBoth options, good pricing, discreet
Roman (Ro)Both, strong medical support
KeepsBoth available
Rex MDBoth, often very competitive pricing
BluechewChewable versions of both

BlueChew is worth mentioning specifically if swallowing pills is a concern.

All require a brief online consultation, which is legitimate and appropriate since these are prescription medications.
