no u dont have to store it in a fridge
im assuming its just an oral suspension and not an injectable....
reason i ask is i have an injectable version
it lasts for a fucking long time bro
if u evaporate it then u will just be left with the powder and no way to dose it properly......
so just shake it well and pop the needle off of a syringe and suck up the proper dosage and ur done
im sure it comes with a dosage dropper but using a syringe without the needle is the only true way to get a proper and accurate dosage
