On the topic of breeding season. During breeding season there are two things that appear on the male. 1 is the Nuptial Pads used for gripping the female and 2 the odontoids extend in length so that they can fight rival males.

A 7" female is a big NO! Females don't get that big. 5" to 5.5" and 6" is really pushing it. Not saying that it doesn't happen, but highly unlikely.

Oh and Lija there is no Super Secret Growth Formula.
