Reconstituting a vial

Before you start

Decide how much water to add. More water makes each dose a bigger, easier-to-measure number of units; less water fits big doses in a small syringe. The calculator's "How much water?" tab, or the suggestion in the protocol editor, picks an amount that lands your dose on a syringe mark.

You need: the peptide vial, BAC water, alcohol pads, a 3 mL mixing syringe with a drawing needle (or a 1 mL insulin syringe, in several loads of up to 100 units each), and a label.

Steps

1. 1Let the peptide vial and the water sit out for 15–20 minutes to reach room temperature.
2. 2Wash your hands. Flip the plastic caps off new vials and swab both rubber stoppers. Let them dry.
3. 3Draw the planned amount of water. Push a matching amount of air into the water vial first if it's hard to draw.
4. 4Push the needle into the peptide vial at an angle and aim at the glass wall. Let the water run slowly down the side, never straight onto the powder. The vial is often under vacuum and pulls water in: hold the plunger so it goes in slowly.
5. 5Don't shake. Swirl gently or roll the vial between your palms, then let it sit. Most dissolve in a minute or two; some take 10–15 minutes.
6. 6Check it: the liquid should be clear with nothing floating in it.
7. 7Label it: peptide, mg in the vial, mL of water, date mixed.
8. 8Add it in the app under Protocols → Inventory, so it counts your doses and shows how many units to draw.
9. 9Store it upright in the fridge (2–8 °C), away from light.
