honestly guys i experimented with it like 3-4 times this week and it doesn't seem to have done anything

Yeah p much all of that can be understood as a vitamin d deficient subject having more local use of Vit D (itself a steroid hormone) in the testes if UV radiation is put there

In other areas, the Vit D is used up for other processes, & therefore doesn’t make its way to the testes to increase T

ohh interesting. does that imply that if i kept doing it i'd eventually have enough vitamin D in other parts of my body that some would eventually start increasing T? or nah?

I think the T-increasing effect of UV radiation is through Vit D’s action in the testes. So once you have a sufficiently high blood concentration then it’s just going to stop having any effect on T, after reaching a ceiling
