These TwoStage Cylinders are for the advanced pumper to enlarge both penis and scrotum in the same cylinder.

The smaller opening into the larger chamber keeps much of your abdomen from being pulled into the cylinder. The larger chamber allows for plenty of extra room for expansion.

Many men have been able to pump their penises to 8 inches in circumference, and scrotum to 10 inches in circumference.

Available in four exceptional sizes. Choose yours below.
