If you have honestly tried everything from different kinds of training to different diets, and you can't get past 105, then you are basically fucked. Your genetics are a huge limitation for you. If this is the case, then dbol is the drug for you. use it in moderation at first, with AS MUCH .... i repeat ... AS MUCH protien as you can stuff in your freakin face.
I have said it before, and I will say it again ... Unfortunatly ... Your physique is first determined by egg and sperm. Then dumbells and barbells. You have to work with what you got, which in your case dosent seem to be a whole hell of a lot.
everyday, munch down a few bacon wrapped donuts! lol
