I need some opinions. A friend of mine wants to do deca only to help with a shoulder injury. he's old school. he thinks deca heals, I know it lubricates the joints. that's why I need some advice. if it will benefit? if so, what dose? he is 5' 4" and wieghs about 190 trying to cut some fat too. he might just be screwed. I know his shoulder is!! maybee a cortizone shot and lay off?
