Sildenafil is a PDE5 enzyme inhibitor, meaning it works by allowing blood vessels to expand and relax.

This increases blood flow to the penis when a man is aroused, which improves sexual performance for men with erectile dysfunction (ED).

Sildenafil and Viagra work in exactly the same way, because the active ingredient (Sildenafil Citrate) is the same.

Sildenafil usually starts to work within 30-60 minutes. Maximum erection potential is usually after 1 hour.

It’s important to remember that the pill won’t give you an automatic erection – you still need sexual stimulation to maintain a good erection.

Eating a heavy meal or drinking too much alcohol before taking Sildenafil can also mean the drug is slower to take effect.

For most men, the effects of Sildenafil can last for up to 4-5 hours, although it can range from 2-6 hours depending on the individual. Sildenafil can safely be used daily, if you’re intending to have sex daily, however, the effects of Sildenafil don’t accumulate if you take more in advance. Use it only when you need it.

Tadalafil works by inhibiting the PDE5 enzyme, which is responsible for smooth muscle contraction within the blood vessels.

Taking Tadalafil enables the blood vessels in the penis to expand, meaning that blood flow is improved in the place it matters, when you need it most.

Tadalafil makes it easier to achieve firmer erections – but only when you’re also naturally aroused.

Tadalafil can start to work in 30 minutes, which is one of its major benefits as it can be somewhat quicker than other erectile dysfunction medications.

It is also unaffected by food intake, unlike the common alternative ED drug – Sildenafil (Viagra), so this is another reason why Tadalafil is so popular.

You will need to be sexually stimulated for Tadalafil to work, but don’t worry, you have plenty of time.

Tadalafil lasts for up to 36 hours – giving you a bit more spontaneity in your love life than Sildenafil (Viagra).

Tadalafil can be very handy for a romantic trip away – and also for men who anticipate more regular sex without wanting to pop a pill every time they want to get it on.

Viagra works thanks to its active ingredient, Sildenafil Citrate.

This is a medicinal agent known as a PDE5 inhibitor, which encourages blood flow within the penis. It does this by targeting the enzyme, phosphodiesterase 5, that is responsible for smooth muscle contraction in the blood vessels supplying your penis.

By improving blood flow in the area where you need it, the better the chances of an erection.

Viagra gets to work 30-60 minutes after you have popped the pill – and your best chance of an erection comes usually after an hour.

Yet, there’s no rush. Viagra remains effective up to 4-5 hours after you have taken it, giving you plenty of time to enjoy its benefits.

Be aware that these timings differ if you’ve eaten a big meal of fatty food. This tends to slow the drug’s absorption into your system.

Viagra has a reputation for being a well-tolerated and effective treatment for ED – and it’s a reputation that is deserved.

Sildenafil has been shown in trials to be effective in about 80% of men – and it routinely outperforms other options of erectile dysfunction medication.

However, every man is different. If it is not effective the first time, we recommend you try 8 separate occasions before choosing other options.
