    have you seen an image of an abscess?? just say no
    are you saying no you cannot bake gear? i've read it from countless sources on the topics of sterilization and homebrewing. interested in hearing why you say baking is not possible.

    most people say 20-30 minutes at ~250degrees, maybe repeated multiple times, and poke a sterile needle in the rubber to let the expanding air vent. this temp will not melt the rubber.

    although, I just read this, which makes a lot of sense, and would still be completely effective.

    We got to talking about sterilizing steriods, especailly home brewed tren. He says that baking tren or any steroid at 250 degrees F is not a good thing at all. He says that it will denature some of the hormone. He went on to recommend pasturization at between 150 to 170 degrees F for 30 minutes. Buy a candy thermometer and heat water to this temperature range then put the vials in the water. Before doing this be sure to withdraw air from the vial to allow for safe temperature expansion of the remaining air.

    Interestingly Bill Roberts says the exact same thing.

    ...

    Ya leaving a pin in the vail is a great idea but be sure to cover the majority of the vial with the hot water.

    BIll Roberts says that even a few minutes at 170 degree F will kill the bacteria but that the oil will need time to reach this temp thus the 30 minutes. This is what is done to kill the bugs in milk and milk can have some pretty nasty bacteria in it.

    My buddy says that this temp will not destroy heat spores but either will 250 degree. Luckily spores are few and far between

    My pathologist friend added that a .2 micron filter will also do the trick. I'll ask him if this will trap spores
