Amid a ban on Viagra in Pakistan, some men are buying 'Sanda Tel', which is freshly-extracted lizard fat marinated in scorpion oil and seasoned with pungent red spice, a report has said. The "quack aphrodisiac" oil, which reportedly has no scientific backing, is being sold with claims of promoting sexual stamina. It's extracted from Hardwicke's spiny-tailed lizard.
