people bake their gear bro 
You know, I've got to question effectiveness of the drugs after they do that. You see this "baking" recomendation all over the internet, but when you think about it, it doesn't really make sense. To heat food to safe (meaning low bacteria) levels the recommendations are heat to an internal temperature of 160-170F. This doesn't eliminate bacteria, it just decreases the number to what is considered a "safe" level that then the body is able to deal with with the immune system and stomach acid defense mechanisms. To me there is a huge difference between heating something to eat and something to inject. There is really no innate defense mechanism when you inject the bacteria, they are going to grow and if they've been heated to a nice warm temperature before injection, they may be completely primed for growth.
To sterilize something with dry heat (as in using an oven) you need to heat the oven to 320F for 2 hours. There is a rapid method that uses something like 400F for 12 minutes if the material is dry and unwrapped. Just because you are heating a liquid doesn't mean you are using moist sterilization. Boiling something in water doesn't really "sterilize it" it kills some forms of bacteria that cause disease, but boiling in water---a rolling boil--is ineffective against some bacteria, fungi, and viruses. To truely sterilize with moist heat you must heat at 250F for 15 minutes UNDER PRESSURE as in an autoclave. Most people don't have autoclaves sitting around and if you try to autoclave something in a glass vial, the vial is very likely to break.
Now, if you look at a bottle of Androgel or a bottle of HG test cyp or a bottle of equipoise or winstrol, they all have storage recommendations of between soemthing like 60 and 85F. Think about it, I can't see how heating these chemicals over twice a recomended temperature (or much higher than that) won't cause a heat induced breakdown of the active ingredients and/or the oil carrier. If its water based, you are going to evaporate carrier liquid if there is any sort of venting of the vial to prevent bottle breakage, which will change the concentration.
The bottom line, I really think the "heat it in the oven" suggestions are internet bullshit. They just don't make sense to me when you think about the basics of dry heat sterilization and chemical makeup of drugs.
