I have a winged scapula on my right side which makes my right shoulder rounded which in turn makes my right pec shorter than my left pec and slightly smaller. Follow all of that? Anyways I have been doing rehab work on it(chest stretches to lengthen pec muscle, face pulls, cable rows, lat stretches, and wall stretches to help and it is SLOWLY improving,but I am not satisfied).

Do you guys think adding IGF-1 would help with a winged scapula and the problems that arise from it?

Also would any other of the supplements mentioned be beneficial?
(I have access to just about anything)

In Addition are there any other exercises or anything that would help?
