Thank you!!!No stupid questions.
Bromobutyl stoppers are fine up to 260f, Chlorobutyl to 270f.
All of the ingredients, oil. BA, BB, and Test C, E, U, and every other AAS raw I'm familiar with are stable at 170-200F for reasonably long periods of times. Certainly up to an hour will have no consequential effect. Nothing will boil or create pressure that could pop the stopper off at those temps either..
