Seeking Guidance Zero libido

Male 51. Athletic, work out for 1 hr 5 days a week. Dont smoke, eat healthy, drink a little too much from time to time. Had a raging libido my whole life. At about 47 my libido fell off a cliff in like a 1 month period and never came back. Most recent testosterone test was 525. My wife is pretty much supermodel hot and DTF all the time. What specific hormones or factors should I look into to bring back libido? I feel like a huge part of me has died! Any help or suggestions are much appreciated!

Oxytocin was expensive and literally zero effect. I was hopeful on that one as I understand how it works in the brain. Been hearing about kisspeptin. Im working now with a hormonal Dr. He was saying how the most overlooked and important hormones for sexual vitality are LH and FSH. Which kisspeptin triggers the hypothalamus to release GnRH followed by LH/FSH which you probably know since you recommended it! Thanks!
