Sometimes you can’t teach an old dog new tricks. There is a ton of research out there proving your point. If he’s too stubborn your probably wasting your time unfortunately.
What @blshaw said. Highly doubt no matter what you show him he will change his mind. Remember, he’s the prof. He is smarter than you.
If you are getting benefit and your bloodwork supports what you are doing than why do you need to convince him of anything? Let yourself be the guinea pig and prove it to him with your data.
Just out of curiosity how old are you?
THE EFFECT OF TESTOSTERONE REPLACEMENT THERAPY ON PSA
Several studies have been conducted to analyze the impact of testosterone replacement on PSA. Except for a rise in PSA shortly after initiating testosterone therapy, there is no increased risk of developing prostate cancer while on testosterone replacement therapy
CONCLUSION
No clear relationship has been demonstrated between testosterone replacement and the risk of incident prostate cancer in any recent and carefully designed studies
There was never any proof of testosterone causing prostate cancer, it was a a myth created by doctors. The data says the opposite, declining testosterone and prostate cancer risk are strongly linked.
I have a father like this, he’s insecure, stubborn, and has a big ego.
I quit trying to convince him years ago.
I find it fascinating that someone can believe something without any proof, and then, when proof of the contrary comes out, it’s not believed, strange, indeed.
