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 a specific occasion
- Generally cheaper
Tadalafil (Cialis generic)
- Works in 30-60 minutes
- Lasts up to 36 hours
- Better for spontaneity or daily use
- Slightly more expensive but very flexible
Most men prefer tadalafil for the longer window, but sildenafil works well if timing is predictable.
Services Offering Both
- Hims (hims.com) - offers both, competitive pricing, discreet shipping
- Roman (getroman.com) - offers both, includes online doctor consultation
- Keeps - primarily hair loss but also offers ED meds
- Lemonaid Health (now part of 23andMe) - offered both
- Bluechew - offers both in chewable form, which some find faster-acting
My Recommendation
Start with Roman or Hims - both have licensed physicians, offer both medications, and have transparent pricing. Try tadalafil first given the flexibility it offers.
Always consult the online physician honestly about your health history.
