Verbatim response from Claude

Sildenafil vs. Tadalafil: Quick Comparison

Sildenafil (Generic Viagra)

  • Works for: 4-6 hours
  • Best if: You want something taken as-needed, closer to when you need it
  • Take it: 30-60 minutes before activity
  • Typical dose: 25-100mg

Tadalafil (Generic Cialis)

  • Works for: Up to 36 hours
  • Best if: You want more spontaneity or plan to take it daily
  • Take it: Can be taken daily at low dose (2.5-5mg) or as-needed (10-20mg)
  • Generally preferred by many men for flexibility

Services Offering Both

Hims - Offers both, competitive pricing, slick app experience

Roman (Ro) - Offers both, strong medical oversight, very straightforward process

Keeps - Offers both, good pricing

Bluechew - Offers both in chewable form, faster absorption, popular option

Teladoc/GoodRx Care - Telehealth platforms that can prescribe either

My Suggestion

Ask for tadalafil if you want flexibility. Try Hims or Roman - both have licensed physicians, transparent pricing, and discreet delivery.

Always be honest with the prescribing doctor about your health history.
