The boner
you get that will rival blue balls. Caused from going to long between nut busts. May or May not be influenced by workout supplements. Tren, D-aspartic acid, Horny goat weed, Tongkat ali, and a few others can cause it. Will get a boner that throbs like the
Incredible Hulk, veins ready to burst,
mushroom tip hard as a cinder block.
