At what age do Russians stop growing?

[Talka]

I got my Russian tortoise back in 2011 and I measured his shell, and it was 4 inches long.

When I got him, he was very sick. He had worms, and the vet I took him to overdosed him with antiprotozoans and nearly killed all his gut microbes. So I had to feed him probiotics for months. After 2 years he finally reached a healthy weight, and recently I noticed growth lines and he felt heavier.

Measured him and he's 4 and a half inches now!

Would this give me a clue as to how old he is?

I think technically, tortoises never really quit growing. As long as they have good food and are healthy they should keep growing, I think it just gets slower as they get older. But there really is no way to tell age at all. My tortoise has grown an inch in four years.

Correction I've had my tortoise for 2 1/2 years.
