Despite its popularity in some circles, Gerovital H3 faced skepticism from the Western medical community. Many scientists and doctors questioned the validity of Aslan's claims and the effectiveness of the drug. Concerns were raised about the lack of rigorous clinical trials and the potential for side effects.

Ana Aslan defended her work and the benefits of Gerovital H3 throughout her career. She argued that the drug had significant anti-aging properties and that it could improve the quality of life for elderly individuals. She presented her research at conferences and published articles to support her claims.

The debate surrounding Gerovital H3 continues to this day. While some people swear by its benefits, others remain skeptical. The drug is still available in some countries, but it is not approved by regulatory agencies in others.
