However, the Scotland wing admitted he needed to be reined in by the club's medical staff to stop him making his comeback during last week's defeat to Exeter.
The win over Toulon saw Franco Smith's men seal their place in the last 16 of the tournament. With the European competition having a break until April, focus now turns to Scotland's Six Nations campaign and games in the URC with Warriors but Steyn was happy to get a full 80 minutes under his belt ahead of linking up with Gregor Townsend's squad.
Steyn said in The National: "I was hoping to get back last week and I had a bit of a tussle with the physios! Unfortunately it was just the way it worked out. Because we hadn't trained the week before I hadn't had any team training and they were a bit worried from a loading point of view. I was gutted not to be out there for the Exeter game but chuffed to get a win at home."
Steyn's spell on the sidelines gave him a chance to catch up on family business back in South Africa.
"I did my best. I was due some time off anyway, post-World Cup, so I got back to South Africa for a week for my dad's 60th which was brilliant, and a much needed break.
"But other than that I was in and about and as soon as I could run I got back on the water-carrying duties and did both Edinburgh games and Exeter.
"I said to myself just to keep it simple and do the basics, carry well and work hard and you do. Training is great for that. Having two weeks of team training before the game is really good for that, you get your sharpness up and get into a rhythm."
