I have used a post workout shake that heals the shoulders.
But I used it before I was on T therapy so i am not sure if it would work for me now...but it definitely worked and healed them after around a week or so......this was several years ago when I had a nagging problem....guess i would of been around 55 then.
Never got to understand the science of how it worked....but it did so it might be worth a shot.
I will dig around for the info on it and see if I can find it.
