Thanks mranak! Gotta admit I like the ambience around here.
Peace,

natural, non-pasteurized milk is really gaining in popularity.coloradosteve said:would you drink milk if it wasn't pasteurized?

I was thinking about asking you what the fuck you are talking about, but then I realized I don't give a shit.TxLonghorn said:If there's one thing I hate, it's motherfucking fluffy bunnies. And snakes on planes, I hate motherfucking snakes on motherfucking planes.

Oil being a very poor thermal conductor as compared to water and will insulate the bacteria. Heating to 200F for 10 minutes is the equivelant of putting a roach in the microwave. All it's gonna do is piss him off. Plus we have not even touched on pyrogens or endotoxins from gram negative bacteria which would require heating to 480F+ for 3 or 4 hours.
Check the link below and make sure to review Table 4.

"Results of the preservative screening tests showed that the formulations containing 0.75% and 0.5% benzyl alcohol are potential candidates to meet the USP/EP criteria (Table 4). Both formulations demonstrated a complete kill of the tested bacterial and fungal species after 7 days."
One more reason why I never brew and shoot. Give the BA time to get to anything the filter missed.

I was commenting on uridium's custom title as well as throwing in some humor by referencing Snakes on a Plane which opened this weekend, starring Samuel L. Jackson, hence the m-f profanities.

Sorry about so long to respond PC probs. Anyway it not an either/or thing Steve. If you feel it helps go ahead and do it. What I'm trying to tell you is that the science doesn't support it.coloradosteve said:Your putting me in an either or situation when we are agreeing on most everything.
Not to beat a dead horse but washing your hands is effective due to the alkalyn nature of soap and everything else listed there consists of 70% or more H2O not oil.coloradosteve said:The heat would be effective at killing most bacteria illregardless of the medium they are in.
Do you wash your hands?
Do you cook your food?
Do you drink pasturized milk?
Do you eat canned food (low acidic)?
All these products are treated with heat to kill bacteria
Do you understand the reason for high heat for long periods of time is not to kill the bacteria, but to kill the endospores?
A-10 said:I figured I'd play it safe and bake my prop and tren after I made it just to humor myself. Cooked it for an hour at 275, let it cool with the pins in, etc.. Now theres little 25g holes where I left the pins in the stopper. I thought it'd be fine but when I turned the vial upside down to draw a little bit started oozing out, maybe a drop or so. Fuck.
I really dont feel like ordering up just 2 50ml bottles to transfer it. I was thinking maybe a little dab of superglue or something? I won't be baking my shit again.
Dry heat sterilization of oil-based preparations is ineffective. Some people recommend 250F, which is the temperature used in most autoclaves. These devices use pressure and wet sterilization and will work on aqueous solution but not on oil based. The time required to kill a known population of microorganisms in a specific suspension at a particular temperature is referred to as thermal death time (TDT). However, oils slow heat penetration and increase TDT. Therefore dry heat sterilization is less efficient than an autoclave and requires more heat and time. If dry heat sterilization alone is used the heat must be raised to 320F-340F for 2 to 4 hours. This would damage many of the hormone preparations we make.
Your best bet is to follow sterile practices, use 2% BA and filter with a .2um filter.
