The Catalog, Decoded
Megalis 20: The Generic Cialis Most Americans Have Never Heard Of
Same active ingredient as Cialis, full strength, a name you won't recognize. Here's the decode.
Megalis 20 is one of two full-strength options in the catalog, alongside Sildatron-100. If Sildatron is the sildenafil line, Megalis is the tadalafil line — and the naming logic works the same way once you see it once.
What Megalis 20 actually is
Megalis 20 is a generic formulation of tadalafil at 20mg — the same active compound sold as Cialis® in the U.S. The "20" refers to strength in milligrams, which happens to be the highest commonly available tadalafil strength. This is the full-dose version, not a starter dose.
How tadalafil differs from sildenafil in practice
The active ingredient is genuinely different from sildenafil, not just a rebrand. Tadalafil has a substantially longer duration of action — commonly discussed in terms of up to 36 hours versus sildenafil's several-hour window — which is why tadalafil is sometimes prescribed at a much lower daily dose (2.5–5mg) rather than an as-needed higher dose. Megalis 20 is formulated for the as-needed use case, not the daily-low-dose one; if you're specifically looking for a daily-dose tadalafil product, that's a different strength than what's listed here.
Pricing
Megalis 20 is currently listed from $56.00 to $252.00, again reflecting pack-size variation rather than a single fixed price. Check the product page for the specific pack breakdown before ordering — we don't maintain a live price feed here, so the listed range is a snapshot, not a guarantee.
| Product | Active Ingredient | Strength | Starting Price |
|---|---|---|---|
| Sildatron-100 | Sildenafil Citrate | 100mg | $27.60 |
| Megalis 20 | Tadalafil | 20mg | $56.00 |
Before you order: tadalafil, like sildenafil, can cause a dangerous drop in blood pressure when combined with nitrate medications. Its longer duration of action means that interaction risk window is also longer. If you take nitrates or have cardiovascular disease, talk to a doctor before ordering — or consider the Healthymale prescription path instead, where a provider reviews this for you.
