EDIT: Removed the physical aspects because half of you twatwaffles still look at picture books and didn't actually read what I said. TLDR - Stop yelling "testosterone, bro!" at each other and do your fucking work, toolbags

I see testosterone bandied about in the RP world like the magic elixir that will turn you into the man you want to be. Spoiler alert, it's not, necessarily. 

You can do all the things you want to try to boost your numbers naturally, it probably won't make a lick of difference, and isn't worth it for the sake of chasing better T. 

Lift heavy, eat right, drink less, and sleep more. Do those things because they make you a better version of you. They may or may not affect your T levels, and ultimately it doesn't matter. 

In 2014, at 28yo, I was racing bicycles pretty seriously. I was 170lbs, I ate very little protein. I drank more alcohol than I should have. My libido was shit. I was a little bitch anywhere outside of a bike race. But my testosterone level was 800 ng/dL. 

I didn't like who I was and started making RP changes before I even knew what RP was. I quit fucking around with bikes and cardio and started lifting.

(Lifting TL;DR - get Mark Rippetoe's books, both the blue and grey one. Read them. Just do the fucking program(s). Profit. End of lifting discussion.)

I got my diet sorted and my macros figured out.

I got strong and I got big. Everyone else's approach and response to me changed. But it still took me a while to figure out what I could now get away with, and my libido was still shit. My T was 650 ng/dL, after years of "doing it right", go figure.

Exogenous testosterone. Look guys, it's the 21st century. Use the tools you have available. Quit fucking around trying to boost your natural T levels. Your body is not a temple, it's a laboratory. Better living through chemistry. If you're over 30, and have low T, just start injecting already. Yeah, it's steroids. Yeah, there's a stigma. No, you don't talk about it with anyone. No, you don't give a fuck what your wife thinks - but she'll probably offer to help inject once you start.

Here's my takeaway - Unless you have super low natural T before you start you can take massive doses of testosterone and it will not change your thoughts or attitude one single bit.

Testosterone will NOT un-fuck your mind. You still have to do that work for yourself. In my experience - which is running up to 1,000mg of testosterone a week - my compassion, empathy, anger, and libido levels do not change AT ALL. Even learning to balance estrogen levels depends entirely on physical cues for me. I have no emotional changes from high to low E levels.

If someone says T changed those things for them they were either super low T before or it's placebo. 

So go blast some testosterone and see for yourself. If it helps your head by adding some physical self-confidence, all the better. Go over to r/steroids and read the wiki. There's some really smart guys over there. 

You and only you can fix the shit in your head. Giving less fucks, figuring out what you want, and cultivating the hunger to go get it are NOT a function of your T levels. Those things are solely a function of your will.
