With your test levels being in the 500-600 range you may not need testosterone treatment. However, there's something else you need to keep in mind. What are your free testosterone levels? It doesn't matter what your total levels are if your free levels are low. For example, this past Friday we had a client with total levels at almost 700 yet his free levels were 6 and as a result he was suffering heavily from low testosterone symptoms. How about you? Are you suffering from low testosterone symptoms? If so it might be a good idea to see where you're at, find out what your free and total levels are and go from there.
