Ampoules are usual packing for injectable anabolic steroids, especially to carry one-time dosages.
An ampoule (also ampule) is a small glass sealed vial which is used to contain or preserve a fluid.
Pharmaceutical ampoules hermetically sealed by melting the thin top with an open flame, and are designed with a scoring around the neck break ring around the neck or a small cut on the neck. When pressure is applied, the top will break off and the medicine can be reached.
After opening the ampoule, the solution is filtered to remove any glass fragments which may have fallen in the solution when the ampoule was opened.
