I have MRI's to prove that var, deca and 5 months of GH did nothing to heal a partially torn right bicep tendon. After a year I had another MRI done and it showed a small tear was still there.
The DR who has worked with many professional athletes looked at me and told me if I wanted it to heal I needed to stop the AAS. I never told him I used any.
That is just my case though. I worked with all the top Dr's in my area on the injury too.
