hello woodsy,
the hospital group is a big no no,many guys have been there and ended up with an unsatisfactory result.
the only doctors doing recognised work in the uk are the farjo's.
if you want to know how you will look 3 months post op take a look in the mirror today.
a small majority of guys only start to show signs of growth at this stage,most can see a good diffence at 6 and for some it takes longer.
there is no way of knowing how you will look post op until you ARE post op,and even then these proceedures are not guarenteed.
it seems to me you are new to all of this,you must research this and other sites and try to educate yourself a little before making any major decisions.
you've made the first step by asking advice on here,listen to what the guys here tell you and for godsake avoid the hospital group like the plague!
good luck.
