if testosterone converts to estrogen via the aromatse enzyme, and estrogen helps with collagen synthesis, then why can't test benefit joints/ligaments by proxy? (as long as aromatase is not being killed via ai)

nandrolone doesn't "heal" directly, but why can't connective tissue with more water content (if that is what nandrolone does) heal more easily/faster than without help?

just some curiosities i have

i have found an increase in sodium intake (from around 2g to around 4 g per day) helps my rotator feel better
