Sildenafil vs Tadalafil: Quick Comparison

The Drugs

Sildenafil (generic Viagra)

  • Works for 4-6 hours
  • Take it 30-60 min before activity
  • Better if you want it "on demand"
  • Generally cheaper

Tadalafil (generic Cialis)

  • Works for up to 36 hours ("the weekend pill")
  • More spontaneous - less timing pressure
  • Can be taken daily at low dose
  • Slightly more expensive but very popular

Which to Choose?

  • Tadalafil is most popular for convenience and flexibility
  • Sildenafil is fine if cost is the priority and you can plan ahead

Services That Offer Both

  • Hims - offers both, easy online consultation, competitive pricing
  • Roman (Ro) - offers both, well-reviewed medical process
  • Keeps - offers both, straightforward pricing
  • Rex MD - offers both, often very affordable
  • Bluechew - chewable versions of both (unique format, faster absorption)

My Recommendation

Start with tadalafil for flexibility, and try Roman or Hims - both have transparent pricing and legitimate licensed physicians reviewing your case.

Always be honest in your health questionnaire for safety.
