does humatrope come with a pen device?
Humatrope comes in 3 pen sizes. The pens can be used for up to 3 years from first use (not talking about the cartridges here) and there is a place on the pen to note the date you first used the pen. This can save a bit of money as you can just buy the humatrope cartridges instead of the pens all the time. Humatrope pens come in different sizes.
