During tonight’s all-new episode of The Real Housewives of Orange County — Season 9, Episode 7 (“Choke-Lahoma”) — Tamra Barney and her son, Ryan Vieth, had yet another heart-to-heart. After his mom gave him a tough time for not being career-focused a few episodes ago, tonight saw Ryan admit to his mom that he’s been taking Human Growth Hormone.

According to WebMD, HGH can be used to treat a number of medical issues in both children and adults, “but the most common uses for HGH are not FDA-approved. Some people use the hormone, along with other performance-enhancing drugs such as anabolic steroids, to build muscle and improve athletic performance.”

Ryan — who is recently engaged — was discussing estrogen with his mom on the couch when he casually brought up the fact that he uses HGH, saying, “I have less fat on my body, my muscles are more dense, and my hair’s even gotten better.”

Tamra seemed shocked during the conversation, but admitted in her one-on-one conversation that she wasn’t taken aback. “I’m not surprised at all,” Tamra told the cameras. “Ryan’s always struggled with body issues and he’s always looking for the easiest way out. He wants things now and he wants things fast.”

These are the side effects WebMD lists as a result of using HGH:

  • Nerve, muscle, or joint pain

  • Swelling due to fluid in the body’s tissues (edema)

  • Carpal tunnel syndrome

  • Numbness and tingling of the skin

  • High cholesterol levels

  • Increased risk of diabetes and contribute to cancerous tumors

Tamra, being the caring mother that she is, then asks Ryan if he's completely sure he's taking every precaution to ensure that he's being careful with where he gets the HGH. He claims that he checks the serial numbers but that what he does is “sketchy and probably illegal.” After a visit to the doctor and pending blood labs, we'll have to wait until next week to see what the medical professionals say about Ryan's bulk-up methods.

Hmm, what do you think about Ryan’s big confession? Hit the comments and sound off!

The Real Housewives of Orange County airs Monday nights at 9 p.m. ET on Bravo.
