You seem to miss the point of trying the nasal gel, but I'm not shocked. It would be a temporary measure to see if your son was helped by a boost in testosterone without shutting him down. If it works, great. He can then look at long-term treatments, like injections, as he knows that TRT is his future. If it didn't work, then he can come off immediately without doing any harm to his system or needing him to make another big adjustment. You've described him as unstable and a complete mess. Considering his clearly fragile condition, he probably wouldn't do well with a jolt to the system coming on and off and the potential for his hormones to get at least temporarily pretty out of whack.
I get that you've abused steroids in your past and you choose conspiracy theories over science. Blood tests don't matter to you, the latest scientific research doesn't matter to you, the latest treatments don't matter to you. The only thing that matters to you is 40 years of running gear and your one size fits all approach here. There's no sense in discussing costs or numbers with you (although the Empower version of the nasal gel is less than $100 per month). I would hope that you, your wife and your son could collectively scrape up a few hundred dollars to approach your son's treatment in a more scientific and responsible manner, but so be it.
Call me a hypochondriac if you want (there's some more name calling, but at least you spelled it correctly) for wanting to take a scientific, measured approach to treating someone who can't get his act together as a 26-year-old grown man. If that's what a hypochondriac is, then I'll gladly take that title. I think your son needs a lot more help than TRT and that you're using his testosterone level to help him avoid responsibility for his actions and decisions (not doing him any favors there as a parent), but you have tunnel vision. When other young guys come on this board, I hope their takeaway is to talk with a qualified doctor in the field, get the appropriate tests to try and determine their problem, and be responsible in their treatment. My hope is that they won't get treatment advice from Lyle Alzado or Jose Canseco. If that's not the consensus on this forum, then it's time for me to check out.
