There are people on here far more knowledgeable than me, I'm sure, but AFAIK no anabolics are going to help your tendons. You can build muscle, but you need to exercise to make a difference with the tendons. Dbol and deca was the first cycle I ever did, and it's great for a simple and affordable way to see what your body can do. It's good that you are thinking about running nolva with it, but don't forget to protect your liver with some milk thistle, and your cholesterol and BP with garlic, celery seed, hawthorn berry, and a policosanol/red yeast rice combo.
And...if your doctor really thinks you need to pack on some mass (or you can somehow con them into thinking your way), try for a prescription for Oxandrin!!!
