I asked this question before with no success, I will give another try:
I have torn ucl (ulnar collateral ligament ) in left elbow and damaged ucl in right elbow. Was told by a doctor to try to rehab the left elbow first , build muscles that would perform the function of torn ucl.
I read that igf-1 might help my problem. Any input? My goal is to have localized growth of the target muscles (left and right elbows) and repair of damaged ligament (right elbow) with minimum side effects and minimize traceability of the substance.
