Age doesn't effect the way winstrol works but most older individuals already have joint issues. Adding winstrol into the mix and it's a recipe for disaster.
At your age, I personally wouldn't use winstrol but if you want to use it - use a good joint supplement and fish oil when using it. It won't prevent the joint pain completely but it'll reduce the pain at least some what.
One of the sponsors on the board needtobuildmuscle.com makes a really good joint supplement. Check that out.
For the fish oil, just go to Costco.
