Original Viagra unopened box still in foil. 4 tabs per box. $30 per box. Got from doctor. Made by Pfizer. Unlike other Viagra tat are selling in loose form, mine has the Pfizer hologram on the box to prove authenticity of the product. Most of the Viagra tablets on the market are 100mg per tab. Halve a tab will last 1 whole day. Mine is already 50mg per tab. So save the hassle of breaking the 100mg tab into 2. Get it while stocks last!!
