Vidalista Black 80 mg is a high‑strength erectile dysfunction (ED) medicine that contains tadalafil as its active ingredient and is used to help men achieve and maintain an erection when sexually stimulated. Tadalafil works by relaxing blood vessels and increasing blood flow to the penis, but it only works during sexual arousal — it doesn’t cause spontaneous erections and must be taken before sex as advised by a doctor. Effects can last up to about 36 hours, which is why it’s sometimes called a “weekend pill.” https://www.genericday.com/vidalista-black-80-mg.html
