Well I started T (Testosterone) Gel end of January 2014. And the changes so far have been positive mostly.
My Voice - The first month it started to change.... still going up and down a bit, croaky at times. I haven't lost my voice yet though! I am hoping it deepens much more because its definitely not enough at the moment.
My Skin - Months of horrendous acne. My face, my back, my chest. I went on some medication about a month ago called Lymecycline. I am hoping this improves things and so far, it does seem to be helping but I am still getting annoying and painful spots on my face, the latest one is right on my bottom lip and hurts like hell! My overall skin condition is okay apart from my face, which is definitely much more greasy and so I invested in some good face wash by Loreal for men. Its got those little grains in it, which helps get rid of the grease for the day, which is great.
Hair - Started with very little, 3 months in it was noticeable. My facial hair is improving by the day, especially on my chin and sideburns. My arms are hairy and so are my legs, this is what i love! My wife noticed I am gaining more grey hairs but I am not worried as I am 47! I have a lot of hair on my stomach now, none on my chest.
Body Fat - I am overweight anyway, but its definitely going to my belly now and not my waist, which is a relief.
Periods stopped straight away.
