Honestly best bet is this. If you have good insurance find a neurologist who you can trust. Call up there and tell them your having pains in your testicles. (If you dont say this then insurance WONT pay for all if not the majority of the tests). Have the neurologist run a FULL panel on you. It will show everything man. Honestly this is the best route not only because of the full panel but also the neurologist can actually help dial in your test, show you where your body is peaking and then descending while on test, and help with any problems you may have. Best way to dial in everything. A neurologist can make your cycle so much easier and show you what works for you to the T.
