got 2 10mil vials of test 400 and 2 10mil vials of test proponate yesterday, every thing cool untill i noticed 1 of the test 400 had crystalized a bit i shook f**k out of vial put 1 mil in syringe it took forever lol gave it a warm bath added 1 mil test proponate and done the job. is this way better than giving the whole vilal a bath evertime?
