Post Fin, Low Testosterone -> High, What are Body symptoms?

Ok so ive been off of Pro for about 8 months now.
If you can please give insight on below numbered questions…

Noticing some + changes.

Now i dont have the cash to go get lab tests done right now,
But im trying to figure out what is going on with my body just for my understanding.

summing it up Its my understanding that Generally post fin we suffer from Low T levels thus the low Sex drive, Depression, and lack of energy.

Now that i am beginning to feel better, i feel more aggressive than i ever been in the past few years and energy is returning.

Ive been searching online and did not find signs of testosterone shifting from low to mid/high symptoms of body changes if any. Maybe i just havent felt like this im just wondering if its testosterone thats contributing to my increased libido and energy spike.
1. Any other symptoms i should be noticing like body hair???

2, Anybody else experience this and post blood test ruled it due to testosterone?

Reason why i am inquiring is to confirm if i can link other changes in my body i am not noticing because of lack of data and reinforce that i am on my way to recovery…
3. Also try and explain my weight fluctuation and appetite change…
Up to when i started feeling better i lost a ton of weight low of 178 now im gaining it back - 183. A year ago i was 210

Also can someone tell me what impact testosterone increase or decrease has on weight?

Thank you for your time. :smiley:
