After the Duggar family released a statement Wednesday that 27-year-old Josh Duggar has "checked himself into a long-term treatment center" following his admission that he has been "unfaithful" to his wife, Anna Duggar, multiple reports speculate that the treatment center is most likely Reformers Unanimous in Rockford, Illinois. 

ET has learned that a plane registered to Josh's brother, John David Duggar, left Springdale, Arkansas (where the Duggar family lives) at 10:45 p.m. Monday night, and landed in Rockford, Illinois at around midnight. The plane then left again at 12:25 a.m., landing back in Springfield at around 3 a.m. The Duggars are also clearly familiar with the center -- last October, Josh's parents, Jim Bob and Michelle, spoke at a Reformers Unanimous national conference, and proudly posted about it on Facebook.

"They are an incredible Christian based drug/ alcohol addiction program. While there, we saw our good friends Godfrey and Launa Watson from Jamaica, too. Love supporting organizations and events like these," the couple wrote.

So what exactly is Reformers Unanimous? The Reformers Unanimous Schools of Discipleship is a Christian, biblically-based recovery program. "Our mission is to train and empower men and women to live victorious Christian lives, enabling them to have permanent victory from any and all crippling sins," their letter to potential applicants states. "We represent one of the most successful, if not the most, successful, method in America."

The full cost of the program is $7,500, and lasts approximately six months. As for what a typical weekday is like for the men's program, it includes waking up at 4:30 a.m., having "It's Personal" daily devotions from 5:30 a.m. to 7:30 a.m., then starting the workday at 7:30 a.m. The workday ends at 4:30 p.m., and after having dinner and chapel, participants have an "evening function" such as group Bible study, or mid-week church service. Bed time is strictly 10 p.m.

Weekends are almost exclusively dedicated to faith-based activities, such as Bible class and attending multiple church services.

Electronic equipment, music, and any products containing alcohol such as mouthwash, cologne and aftershave, are prohibited.

"If you have tried everything else, and are looking for something that 'just works' then this program is for you," Reformers Unanimous' website states. "Every part of our program is in place to transform a ‘non-functioning’ person into a stable, successful member of society."

On Tuesday, a source told ET that Josh and Anna had been hiding out at a farm house in the mountains of Arkansas, as the rest of the Duggar family remains behind closed doors in their Springdale, Arkansas compound. Jim Bob was actually spotted in public on Tuesday for the first time since Josh's Ashley Madison scandal, running errands around his home town of Springdale.

Meanwhile, the allegations against Josh keep getting more shocking. Adult film star Danica Dillon, 28, claims that she had sex with Josh on two separate occasions -- both times allegedly while his wife Anna was pregnant with the couple's fourth child, Meredith, who was born on July 19.
