Cape Town - South African-born scrumhalf Ryan Louwrens' buff physique has captured the attention of rugby fans.
Louwrens, 28, who was born in Johannesburg, attended Kempton Park High School before moving to Australia with his parents at age 16.
Two years later, Louwrens returned to South Africa where he played at that year's Craven Week tournament and represented the Valke in the Under-19 Currie Cup.
At the end of the 2009 season, Louwrens, still only 18 years of age, was handed a two-year suspension by the South African Rugby Union's disciplinary tribunal after testing positive for anabolic steroids.
Louwrens addressed the incident in a 2013 interview, saying he was "young and stupid" at the time.
"I wouldn't say I was unaware. I was basically uninformed about the substance. It was pretty stupid and I had two years where I couldn't play rugby at any level," he said.
"I have learnt from my mistakes and I've moved on."
Louwrens played 24 matches for the Force between 2015-2017, before heading to Japanese side Kintetsu Liners between 2018-2019.
Louwrens, now a father of two, signed for the Melbourne Rebels for this year's Super Rugby tournament and made an impact in the No 9 jersey in last weekend's 24-10 home victory over the Waratahs.
A photo of Louwrens training with the Rebels earlier this week has gone viral as it showed off the scrumhalf's bulging biceps.
'That vein is the size of my arm,' one person tweeted in response to the Rebels posting a photo of Louwrens on social media.
Louwrens will start once again in Saturday's Super Rugby clash against the Sharks in Ballarat (05:45 SA time) as coach Dave Wessels - also South Africa-born - continues his search for a permanent replacement for veteran Will Genia, now plying his trade in Japan.
