Suppose I have a 250 mg ampole of Test Cyp and I just want to shoot 125 mg (for one reason or another). I suppose I would draw 125 mg with one syringe and the other 125 mg with another syringe. After that where do I keep the syringe? Room temperature? Fridge? And how long will the juice be "good" until I shoot (meaning: will it spoil?) Thanks!
