Greenstone has been a leader in authorized generics for more than 25 years and manufactures sildenafil citrate, a prescription medicine used to treat erectile dysfunction (ED). The exclusive supply agreement with Roman represents Greenstone’s first collaboration with a direct-to-patient telehealth company.

Under the agreement, Roman’s generic sildenafil citrate offering will be sourced exclusively from Greenstone and manufactured in the same European facilities as branded Viagra - at no additional cost to members. “Greenstone and Ro have a shared commitment to improve health outcomes for chronic conditions by making treatments accessible and convenient. We are pleased to enter into this supply agreement with Roman to provide men with streamlined access to quality sildenafil citrate backed by the quality manufacturing, distribution and support of Pfizer,” said Brendan O’Leary, General Manager of Greenstone. “This initiative reflects the growing trend of consumerism in healthcare and our vision for authorized generics to advance public health and patient adherence by improving access to high-quality, affordable medicines.” “At Ro, we believe patients deserve to know everything about their healthcare-including where their medication is sourced,” said Zachariah Reitano, co-founder and CEO of Ro.
