A month earlier, 27-year-old Aaron Atchley was found dead inside his home.
Eight months before that, Filip Petrovic was found dead.
All three men have at least two things in common, they were taking steroids and they were getting them at Revolution Medical Centers, a Phoenix-based clinic that's currently under state and federal investigation.
"We're looking to see if there is a causal relationship between the death and the treatment or therapy they were being given," said Dr. Craig Runbeck, executive director, Arizona Naturopathic Physicians Board of Medical Examiners.
"You're hitting your body with a biochemical sledge hammer and you're pushing things way beyond where they were designed to be," Runbeck said.
The autopsy reports make no mention of anabolic steroids, but police reports and medical records do.
"Patients die everywhere," said Dr. Jeremy Bula, owner of Revolution Medical Centers. "They didn't die as a result of anabolic steroid use."
But one patient left behind a note.
"Stop using steroids. They will destroy your life or anyone with you," the note said.
Moments later, Brian Stubstad committed suicide.
According to documents obtained by ABC15, he was a patient at Revolution Medical Centers for two years.
His chart indicates he had taken trembolin, a powerful steroid that's not approved for human use.
"Anytime you use a drug that's not approved for human use, there are unknown side effects," Runbeck said.
Was Brian Stubstad speaking from the grave?
According to medical records, he was complaining of depression and mood swings shortly after receiving steroids from Revolution Medical Centers.
In the weeks leading up to his suicide, there were police reports, a pattern of violence, and even an order of protection alleging death threats.
"The story sounds very familiar," said Don Hooton, whose son Taylor began using anabolic steroids five years go.
Six months later, 16-year-old Taylor was dead.
"He was going through severe mood swings," Hooton said. "It went far enough that he went upstairs, took two belts and hung himself."
Taylor Hooton was not a patient at Revolution Medical Centers.
However, his father, who has testified numerous times before Congress, said side effects are all the same, no matter where the steroids are being prescribed.
Every night in Denver, Colorado, Doreen Atchley lights a candle for her son.
Back in April, Aaron Atchley was found slumped over his couch, dead inside his Scottsdale home.
A card from Revolution Medical Centers was found inside his wallet.
Detectives also found steroids - highlighted in the report and visible in crime scene photos.
On the prescription labels is the name of Dr. Carole Eastman, the same doctor at Revolution Medical Centers that prescribed us steroids as well.
Aaron's medical chart from one month before his death, signed by Dr. Eastman, lists prescriptions for anabolic steroids like testosterone and oxymethalone.
"Aaron was concerned about the way he looked," Doreen Atchley said.
"He has a big smile on his face. He wants to show his muscles," Atchley said, looking at a photograph of her son.
But there was another side to Aaron.
He was having mood swings "pretty much right away" after receiving the steroids, Atchley said.
The mood swings were violent.
There were calls to police, but the medical examiner's report makes no mention of the steroids or Aaron's behavior.
"I was surprised not to see that in there," Atchley said.
The autopsy said Aaron died from an accidental overdose, a fatal mixture of alprazolam or xanax, oxycodone, and trace amounts of cocaine.
But Aaron's mother has requested additional testing and so have investigators with the state.
"We're interested in trying to find out if there have been more deaths," Runbeck said.
In all three cases, the medical examiner failed to test for anabolic steroids.
The family of Aaron Atchley had to hire a lab and pay for the tests themselves.
All three doctors at the clinic are currently under investigation.
They have refused our repeated requests for an on-camera interview.
Meanwhile, state and federal investigators are moving forward with their cases.
