I am not 100% but I heard once that u can. Some steroids such as andriol actually benefit from being refridgerated. As I say I am not totally certain, so I'll give this another bump for ya!
fridge is a good place to put your AAS but remember to let them warm up to at LEAST room temp before injecting. I like to fill up my syrindge with whatever AAS then put it in a air tight zip lock and through it in a bowl of hot water for 10 minutes so the oil goes in nice and easy
