Yeah, if you have decent genetics and stay healthy, you can have a good testosterone level well into your golden years. Sure, it's cool just pinning whatever amount of test you want and not having to worry about that, but being a slave to the needle will get old fast for some people and if you can't get any test for any reason(financial, legal, travel, etc) you are FUCKED. You really gotta weigh your options. Your hpta is probably fucked up judging by your cycle history and current health status. Definitely get Testosterone and e2 checked. Prolactin wouldn't hurt either. Get your thyroid checked too. Also do yourself a favor and try to get at or under 15% bodyfat. You will feel and look a lot better. Come back to us with some blood work and i am sure we can help you out. Cialis could help you get an erection, but it won't help your libido so there ain't much point unless you gotta please a lady.
