There is another problem, though, that most don’t think about. What is the interaction between the steroid solution and the syringe components? You see, before the Food and Drug Administration (FDA) approves any drug product, the drug itself must not only be proven acceptably safe for use, but the container’s stability with the drug in it needs to be studied as well. We need to be sure the solution doesn’t break down the components, leaching potentially dangerous substances into the solution. Remember, ampules are entirely glass. Vials are glass with an inert rubber stopper. Syringes are largely made of plastics. At this time, I am unaware of any studies looking at AAS oils and how they interact with plastic syringes for long-term storage. This is just an unknown to me. I can’t suggest it is OK.
