Usually you grow until 21-25 than you stop.
I'm 20 and I have noticed over the past few months, my test increase .. with this my mood and aggresion has gone sky fuckin high along with more facial hair, muscle tone, bigger balls [yes they gone bigger recently] and also I have gone slightly taller.
Anotherthing, I belive 110% the earlyer you start Penis Enlargement the better.
Dont wait till 18 to start if ya can help it, do it ASAP cos the more hormones in your body the better the Penis Enlargement will feed off, cos you neeed these hormones from puberty to get real good growth.
Bare in mind, you can still gain great later in life ... but from my time in Penis Enlargement and life, it seems better to start at puberty, about 13 would be the really best time to start Penis Enlargement ..... I only I knew than *sigh* I'd done a few hundread wet jelqs a night.
I also used to get erections as early as 9 years old, and started wanking at that age also ... but first ejaculated at say 11 or 12 years old.
I might have just high test and hormone levels????? I gain great from minimal sessions in Penis Enlargement, I aint in anyways a reguler with Penis Enlargement like DLD for example, just a few eacHydromaxonth yet I pack over 8.25X7.5 and over 2 inches width when erect .... could I just be lucky?? who knows, but IMHO start young as possible and dont worry about growth cos ya got till 21 at least, maybe even upto 25.
