So my story starts out the same as most
I took a topical hair loss product twice, ended up with severe anhedonia, emotional blunting, anxiety, sexual dysfunction, and minor sleep problems (mostly just sleep maintenance insomnia, could fall asleep fine).
Long story short, got special lab tests done, found that test was decent but DHT was boarding low and estrogen was low. Decided after prior experience with test boosters that that route was a meme and decided to stick a pin in my ass. 200mg split into daily injection, also added Masteron (DHT derivative) at 200mg as an ancillerary. libido came back in waves, some good moments (literally periods of a minute or two sometimes) and periods of zero libido. eventually, the good periods became longer and the bad periods became shorter over the period of a couple of months until I just stopped thinking about it.
I used bacopa monnieri a good amount too, which helped with sleep and libido, I still take it daily.
