Cialis is a long-acting medication. Its effect lasts up to 36 hours.

That is why I think there is no need to take Viagra the 비아그라 구매 next day after Cialis has been taken.

Viagra is the brand 비아그라 구매 name for sildenafil citrate. There is no “super viagra”, 비아그라처방 but there can be other delivery methods for 시알리스 구입 sildenafil citrate – like oral jelly – from other manufacturers.
