When you do any physical activity that is demanding and pushes your limits your testosterone decrease significantly or shuts down completely and only later gets released into the body to build stronger muscle fibers from the micro-tears while you're resting. Back in caveman days, men were always demanded of more physically and evolved like that. Testosterone itself doesn't signify strength or aggression in the same way we think today, the reason we assume that is because of the roid rage that happens to steroid junkies, if you didn't know steroids are synthetic forms of the testosterone your body would naturally produce and is made in a lab so it's not only unnatural but when you take it, you heal alot quicker thereby making faster gains but your hormones get imbalanced. That's not what real testosterone is.
Relevance of this? Broscience isn't my field of expertise, but seems to be yours. I'll have you know testosterone wasn't made for body building. Its primary feature is developing male reproductive tissue. And testosterone doesn't shut down completely, it actually increases at first, and then begins to decrease. It builds muscle fibers? Is that the only way it is reinforced? More broscience pls. Testosterone naturally regenerates with time, and if I recall correctly around 20 times quicker than females do. And yes, I know that steroids boost testosterone levels and are counter balanced with greater oestrogen levels (with time). Testosterone is basically on steroids during puberty, which is why we begin reproducing sperm cells, build muscles and grow so quickly, etc. It's what makes a male a male. I have yet to understand how you jumped from
I learned from a gym owner, testosterone builds, it heals, metaphorically it's female, don't come to me with your brainwashed school "education", it has nothing on reality and I don't like to associate myself with sheep.
To testosterone not being responsible for roid rages. Metaphorically it is not female. That makes no sense, testosterone is a symbol of manhood, thus people with greater testosterone levels seem more manly, not more feminine. To me, it seems like you found something out about biology (which is false, test is more masculine than feminine) and where desperate to show off that false knowledge in order to look intelligent-- failing.
