The mental changes took place almost immediately, to the point that I feel they were more psychological (placebo) than anything else. World definitely felt fantastic.
The first month for me was actually pretty lackluster, and the main change I faced was my body changing tremendously after a change in my diet (no sugars, 0 sodas after them being my vice, fruits and veggies every day, constant snacking, protein everywhere), which gave me a nicer figure. I also suspect a lot of muscle mass was lost.
I had a tingly sensation in my skin often, and especially on the nipples, but nothing significant.
The second month is when things got more intense. My original dose was doubled, and looking in the mirror was like seeing someone else. Breast buds started, and with it came joyous pain. It's not much so far, but I started having to hide it at work. My hair got softer. I stopped using deodorant because I just didn't smell as much anymore, and when I do it's a more sweet scent than the previous male musk. I'm like ten times more emotional, spending entire weekends watching romantic comedies while crying for no reason, then jumping up and down the next day. Skin feels amazing and it's super sensitive.
Currently in the third month which is more of the same. Body hair is definitely slower in coming out now and much less, but sadly still too much. My cheeks are much rounder and now I have the girliest smile. My hands are softer and look more feminine.
