Does anyone here experience some severe testosterone spikes for long periods of time at seemingly random?

For some background on my health i practice mma 3 hours a day 4x a week and do yoga and weightlifting 3x a week. I don't touch supplements or steroids since i don't compete.

I'm on a vegetarian diet heavy in eggs and leafy greens.

I'm 30 now, but since 21 when i started training i have noticed that periodically i experience a feeling of increased hormones for periods of 2 to 8 months at random intervals.

Women become more attractive, even ones i generally find ugly start to look good, i start to feel a meathead contempt for people that i perceive as too weak mentally or physically, my performance in the gym increases, and i just generally have an urge to find other sexual partners. It's not horniness, it's this desire to just get involved with women. I also get an urge to just exercise all the time.

I did some research and see that testosterone levels cycle seasonally, but i seem to experience very drastic spikes for quite long periods at random.

What's interesting about it to me is that i can feel the way i perceive the world change almost overnight.
