What is the best time of day to pin BPC-157/TB-500?

I had shoulder surgery to repair a labrum tear and remove bone spurs about 8 years ago from a lifting injury. Shoulder often feels better for a while and then for months at a time it will be nagging and achy. Wondering if BPC or TB individually would be more beneficial for this or running Wolverine blend. I do also have other random body aches I am hoping to help resolve as well.
