Graybeard, I am 72. My wife is younger and I felt the same way!

TRT is Testosterone Replacement Therapy.

I would strongly encourage you to try Trimix injection, especially before implant surgery. It absolutely works while on Lupron. The Urologists suggest using it no more than 3x a week or every other day but I have heard of guys using it more frequently such as on vacation. They instruct you to start with a lower dose (10 or 20 units). If you don't get the desired result increase the next time by 5 or 10 units until you have a firm erection. As I said, the issue is it staying hard for several hours. If it stays hard for more than 4 hours they instruct you what to do. I've read that this is rarely an issue and is usually because someone takes Viagra at the same time. No need to do that.

The injection really isn't a big deal. Very small needle like used by diabetics. Goes in maybe a third of an inch. Works within 10 minutes or so. The first time I used it it was like magic because I hadn't had a real erection for over a year since surgery.

Glad to answer any other questions.
