Once a peptide is reconstituted, the next step is drawing the right units into an insulin syringe. Done carefully, it’s simple — the key points are gentle mixing, an accurate unit count, and getting the air out. This is educational, not medical advice; confirm your technique with your pharmacist.
Wash your hands, wipe the vial stopper with alcohol, and work out your units first with the free calculator — units depend on the vial’s concentration.
If you’re mixing the powder, add the water gently down the vial wall and swirl to dissolve — hard shaking can damage a peptide. Let it go clear before drawing.
With the needle up, tap the barrel so bubbles rise, then push gently to expel them; redraw if needed so the dose is accurate.
See injecting at home and site rotation. Dispose of the syringe in a sharps container — never recap or reuse.
With the needle pointing up, tap the barrel so bubbles rise to the top, then push the plunger gently to expel them. Redraw if the dose is now short.
Peptides can be fragile; hard shaking can degrade them. Add the water gently and swirl to dissolve.
On a U-100 syringe, 100 units = 1 mL. Read the mark your calculated volume lands on. See the reading-a-syringe guide for detail.
A U-100 insulin syringe sized so your draw fits comfortably (0.3, 0.5, or 1 mL). See the insulin syringe sizes guide.
Always confirm the concentration and keep mg vs mcg straight, and don’t mix U-40 and U-100 syringes. If a number looks off by ten, recheck before drawing.
