I don't have any ACL or cartilage in my left knee and only partial in my right knee. It stinks to have bad knees, I feel for you bro. I did a deca/EQ/Test cycle for my joints and now they feel pretty good. You can't ignore the benefits of supplements like cissus and glucosamine/chondroiden (sp?). I'd stay away from the HGH for now. I think you'll get great mileage with the deca/EQ/Test cycle. Keep the dosage low 200mg/wk or 150mg/wk. The goal is soft tissue hydration not anabolic. Large doses of the same compounds does NOT cause more joint hydration.
