Ide in all honesty say you'de have to be insane to use steds to help tendonitis as its a short term help and as soon as steds are out of system due to you carrying on as normal or infact pushing your training further and heavier weights the problem would be double what it was before using steds to help in first place

I do understand using dbol and deca as they are the best for tendon help,more so deca,but the water retention straining the heart etc to cure a problem for 10 weeks imho is insane.

Go to a doc and get professional help
