Transparent bumped specular

Hi! I've got a question about the transparent bumped specular shader. When i use it it works great, the parts that are supposed to be invisible are invisible and it has a nice specularity and bump mapping. Though there's a pretty huge "but" here, the entire model even what's supposed to be completely visible becomes semi transparent; despite that everything supposed to be visible is as white as it gets on the alpha channel.

I anyone has a solution or know why this is happening i would be ever so gratefull if you would share it. :)
