I remember someone telling me after you open it you should store it in fridge
is that right?
LOL no dude.... Its supposed to be stored at room temp. Your closet or sock drawer would be ideal...
Injecting cold ass oil is also not a good idea. I warm my gear up with warm tap water so it is easier to inject and it helps with oil dispersion inside the muscle.
Since your gear has been in the fridge it may actually have crystallize up and you'll have to heat the gear up to get the test crystals to redissolve.
