The Trial ED Pack is a sampler: sildenafil 100 mg, tadalafil 20 mg and vardenafil 20 mg in one pack. Its purpose is not value — it is to answer, at small cost, the question every man asks first: which of these three actually suits me?
Why trying more than one is reasonable
The three molecules are close cousins with genuinely different personalities, and there is no reliable way to predict from the outside which one a given man will get on with best. They differ in how fast they start, how long they cover, how they behave around food, and which side effects they tend to produce.
| Sildenafil 100 mg | Tadalafil 20 mg | Vardenafil 20 mg | |
|---|---|---|---|
| Onset | 30–60 min | From ~30 min | 30–60 min |
| Window | 4–5 hours | Up to 36 hours | 4–5 hours |
| Food | Fatty meals delay it | Little effect | Fatty meals delay it |
| Typical niggle | Flushing, blue visual tinge | Back or muscle ache | Headache, flushing |
| Full page | Sildenafil | Tadalafil | Vardenafil |
How to run a fair comparison
A trial pack is only useful if you test properly, and most people do not. Four rules make the result mean something:
- One molecule per occasion, never two in the same 24 hours.
- Leave a clear day between them — longer after tadalafil, which is still present the next day.
- Keep the conditions similar: same rough timing before sex, no heavy meal, no more than a drink or two. Otherwise you are comparing evenings, not medicines.
- Give each a fair chance. A single disappointing attempt says more about nerves than about the tablet — which is the honest limitation of any trial pack, and worth knowing before you buy one.
The safety rules are identical for all three
These are all PDE5 inhibitors, so the contraindications do not change between them:
The absolute rule applies here as it does everywhere in this class: never combine this with nitrates (glyceryl trinitrate, isosorbide) or amyl nitrite "poppers" — together they can cause a dangerous fall in blood pressure. If you develop chest pain after taking it, tell the paramedics or the emergency department what you have taken, because nitrates are the treatment they would otherwise reach for.
- One dose in any 24 hours, of any of the three.
- Care with alpha-blockers, other blood-pressure medicines, and strong CYP3A4 inhibitors such as ketoconazole, ritonavir or clarithromycin.
- Not for men with recent heart attack or stroke, unstable angina, severe heart failure, or very low blood pressure.
- An erection lasting more than four hours, or sudden loss of vision or hearing, needs urgent care.

After the trial
Once you know which molecule suits you, buying that one in a normal pack is considerably cheaper per pill than repeating the sampler — the per-pill prices are on each product page. If the answer turns out to be tadalafil and you dislike planning at all, the low-dose daily route is Cialis Daily. If none of the three worked at a full dose under fair conditions, that is a doctor's question rather than a fourth purchase.
The Australian position
All three molecules are Schedule 4 (prescription-only) medicines in Australia, and combination sampler packs are not registered products here. If you have heart disease, take blood-pressure medication, or have never used any of these before, speak to a doctor first.
What you are actually comparing
| Sildenafil | Tadalafil | Vardenafil | |
|---|---|---|---|
| Onset | 30–60 min | 30–60 min | 25–60 min |
| Window | 4–5 hours | Up to ~36 hours | 4–5 hours |
| Effect of a heavy meal | Marked | Minimal | Moderate |
| Most reported side effect | Headache, flushing | Back or muscle ache | Headache, blocked nose |
| Visual disturbance | More common at 100 mg | Uncommon | Uncommon |
Notice that the first row barely differs. The two columns that actually separate these molecules are duration and which side effect you are most likely to meet — so those are what a trial pack is for. None of the three is stronger than the others.
Keep a note, or the trial is wasted
Three tablets taken weeks apart, with nothing written down, produce an impression rather than a result. Note four things each time: how long you left it, whether you had eaten, how much you had drunk, and what you noticed afterwards — both the effect and any side effects.
Without that, the usual outcome is concluding that "the second one was better" when the difference was really an empty stomach and a calmer evening.
