well.. I'm new here and new to the sport. I'm 18 6ft tall and 165 lb. I'm looking to gain mass. I ve been working out for about 6 months my knowledge and intensity has been snowballing. I have noticed that my left bicep is larger or at least more "peaking" than the right. I'm right handed and I'm guessing this is why... my right bicep is used all the time causing a longer leaner muscle. I'm wondering if this will go away as I gain size or if I'm doomed to be lop sided. any info/tips would be great thanks.
p.s. didn't mean to give my life story you guys just often ask for some back ground
