Is Jeff Nippard a natural bodybuilder?
Jeff Nippard has always presented himself as a natural, drug-free athlete. This claim is supported by his participation in the World Natural Bodybuilding Federation (WNBF), a drug-tested organization. He won the Mr. Junior Canada title in 2012 under these rules.
How is this verified?

Why do some people question his status?
In the fitness community, skepticism about natural status is common for any high-profile physique.
