For some reason my previous source disappeared and I found a new one and I already ordered some vials of deca and test for my next cycle, some experienced guys told me when you switch gears is better to kill bacteria for safety, some info online and people at the gym say hitting it up in boiling water could work and other say hitting it up with direct fire like using a lighter or a candle, what would you guys suggest as the best method to kill bacteria, thank you.
