ABINGDON, Va. (CBS19 NEWS) -- A man from South Carolina has pleaded guilty to federal drug charges.

According to a release, 37-year-old John Franklin Cochcroft of Lexington, South Carolina, pleaded to a count of introduction of a new drug into interstate commerce with the intent to defraud and mislead and one count of illegally manufacturing and distributing anabolic steroids.

He was the owner of a supplement company that manufactured and shipped unapproved drugs and illegal steroids to members of the bodybuilding community.

As part of a plea agreement, Cochcroft will forfeit more than $200,000 in proceeds he made from selling fraudulent dietary supplements.

“The FDA plays a crucial role in safeguarding the nation through its process of vetting drugs for efficacy and safety.  When individuals bypass that process, they jeopardize the public’s health and must be held accountable,” said U.S. Attorney Christopher R.  Kavanaugh. “My office is committed to keeping the citizens of the Western District of Virginia safe from individuals and companies that sell potentially hazardous products laced with illegal controlled substances, and I am grateful to the FDA-OCI for their diligent work on this case.”

The release says Cochcroft admitted to marketing to the bodybuilding and fitness communities across the country, saying that his “dietary supplements” would increase muscle mass.

He also admitted to making and selling several products that contained a type of steroid known as a Selective Androgen Receptor Modulator or SARM.

The U.S. Food and Drug Administration says SARMs can have negative side effects, including life-threatening reactions such as liver toxicity, heart attack, and stroke.

Officials said Cochcroft aimed to mislead and defraud the government and consumers by making, marketing and selling these kinds of products by using multiple addresses with fictitious business names, working with Chinese suppliers to mislabel drug products as foodstuffs, and intentionally not getting FDA approval for products.

As part of the investigation, various products containing anabolic steroids, which are classified as a Schedule III controlled substance under the Controlled Substances Act, were seized.

Cochcroft will be sentenced in August and faces up to 13 years in prison.
