I am in my mid 40's and recently really noticed this. It felt like some of the teeth in the gears of my mind were worn down and things were slipping. After complaining about it to some peers I was informed this could be due to low testosterone so I went and had that tested. Apparently my testosterone level was that of a 70 year old man so I started testosterone replacement therapy. I can say that it is a complete gam…
This has been in use for 60 or so years but isn’t an FDA approved use of clomid. The primary reason is clomid is cheap to produce and not patented. It’s extremely safe and if you shop around you’ll find a urologist that’s aware of it and will prescribe it - but most urologists get marketing benefits from the rather expensive testosterone replacement products so not all are either aware or are willing to forego the lucrative marketing funds.
I switch to this about 10 years ago after starting testosterone for a few months. I wanted to have kids and I was very worried. I researched the biological processes for testosterone and stumbled on clomid as a relatively well known but unmarketed low T therapy. I went to a top urologist at NYU and he ranted about urologists that don’t use clomid. He gave me a prescription and it worked like magic. Two years later I had my first kid. I still take it at a low dose because I feel great. My testosterone levels are high normal range.
