I would encourage you to never touch it again in any dose. Never use any topical or shampoo stuff that contains DHT blockers either (saw palmetto, etc.).
I took 1mg/day for 6 days. I didn’t realize the cause at the time, but I was having awful emotional outbursts during those few days about trivial shit (like a package not arriving on time). Only later did I realize this was related to the hormones.
My dick went completely numb on day six and I was completely freaked out. Like I literally had zero sensation in it.
Seven months later and I’m only just starting to feel back to normal. And from what I’ve read, I’m one of the lucky ones.
Don’t touch it again. Trust your instinct. You know what caused your dizziness and brain fog.
Being able to function cognitively, emotionally, and sexually is so much more important than retaining our hair.
