For what it is worth...
Been on Ox for 7 + months. Only stopped for 3 weeks when on Fina.
Before the Fina i use 50 mgr Ox/day and 50 mgr Winny ED for 3 weeks, then the next 3 weeks same Ox dosage and 600 mgr Winny/week. I had a right elbow injurie before starting the Winny. Now strange enough after 4-5 weeks the injurie was gone. And more strange after stopping the Winny, injurie came back. I have no explanation for this.
So maybe if doing lots of Winny it helps the joints. I really don't know. Took brewer's Yeast and Zinc to fight acne and this worked perfectly.
