BIG PUN...if you wish to boil gear, follow these steps....and no, it does not kill everything, but does decrease the bacteria count.....fill a pot of water high enough that it will cover the gear in the vial, but not up to the seal at the top, also put something in the pot of water to cover the bottom of the pot, just so that the vial does not touch the surface of the pot (hot spot).....boil your water, and make some kind of contraption with a coat hanger that carefully squeezes the vial where it flairs in and meets with the seal....make sure you remove a pin from a syringe and poke it in the vial to equalize pressure....now dip it in the water being very careful not to submerge the seal at the top of the vial....some turn the heat off at this point and hold it, but i basically boil it like this for about ten minutes and then obviously let it cool before you inject it.....hope this helps......405
