What's in the vial

This section is for people who have already decided to use these compounds. It explains how to prepare and inject safely. None of it is medical advice or a reason to start.

Open your package and you will find a small glass vial with a metal cap and a rubber top. Inside is not liquid. It is usually a tiny amount of white or off-white powder, sometimes just a thin film at the bottom that looks like almost nothing. That smudge is your peptide. It is the full amount printed on the label even though it looks like far too little to be anything.

The powder is lyophilized (lie-OFF-uh-lized), which is a fancy word for "freeze-dried." The peptide was frozen and had its water pulled out under vacuum, leaving a dry, stable cake. Freeze-drying matters because peptides fall apart in water over time. When it's dry, the compound keeps for a long while. Once you add water, the clock starts. This is why you store the powder one way and the mixed vial another. We cover storage later in this module.

You do not inject the powder. You first add liquid to dissolve it, which is the next lesson. For now, just know that the unimpressive smudge at the bottom of the vial is the real thing and that it is dry on purpose.

Start one habit now. Look at the powder before you mix it. It should be white-ish and intact. If the cake arrived melted into a blob or discolored, that is a sign it was handled badly in shipping. More on judging quality at the end of this module.
