Neo-Viagra-Y.R.

(청춘부활)) is a pharmaceutical product produced by the Korea Oriental Instant Medicinal Centre, a state-owned North Korean company.

[2] Although marketed as a herbal health supplement based in Koryo medicine (traditional Korean medicine promoted by North Korea), analysis of the product shows that its active ingredient is 50 mg of Sildenafil (the lowest dose of Pfizer's genuine Viagra tablets), though used in a different formulation to genuine Viagra tablets.

[1] Promotional material for the product describes it as "the best sexual function activator at the moment"[6] which is "officially recognized in many countries for its excellent effect in immediately increasing stamina and it is believed to be better than American Sildenafil (Viagra)".

[3] It is believed to be primarily targeted for export, as a means for the North Korean government (which is subject to economic sanctions) to earn foreign currency.

[3] In 2017, police in Busan, South Korea, arrested three Russian nationals for illegally selling North Korean Sildenafil and Neo-Viagra-Y.R.
