Verbatim response from Claude
Sildenafil vs. Tadalafil
Key Differences
| Sildenafil (Viagra) | Tadalafil (Cialis) | |
|---|---|---|
| Duration | 4-6 hours | Up to 36 hours |
| Onset | 30-60 min | 30-60 min |
| Nickname | "The little blue pill" | "The weekend pill" |
| Best for | Planned encounters | Spontaneity/daily use |
| Food sensitivity | Affected by heavy meals | Not affected |
Which to Choose
- Pick sildenafil if you want lower cost and don't mind timing it
- Pick tadalafil if you want flexibility or plan to take it daily at low dose
Services Offering Both
- Hims - offers both, competitive pricing, discreet shipping
- Roman (Ro) - offers both, good medical consultation process
- Keeps - offers both, straightforward pricing
- Rex MD - offers both, often lower prices
- Wisp - offers both, good for people who want quick consultations
My Suggestion
Roman has a particularly thorough online consultation process, which matters for a medication with contraindications (especially if you take nitrates).
Always consult the prescribing physician honestly about your health history.
