Type the amount you want to measure and this shows it on a 1ml syringe.

This only converts the figure you type into syringe units or pen clicks. It does not suggest an amount. For anything about your own use, speak to a GP or pharmacist.

How to mix a vial

Pens come pre-mixed and ready, so this is for vials only. Take your time; it only takes a couple of minutes.

Room temperature

Let the vial and the bac water come up to room temperature first.

Clean the tops

Wipe both rubber stoppers with an alcohol swab and let them dry.

Draw the water

Draw the amount of bac water shown in the calculator for your size.

Down the side

Let the water run slowly down the inside wall of the vial, not onto the powder.

Never shake

Swirl gently or leave it to dissolve. A few small bubbles are normal.

Storage

Keep everything in the fridge. Once mixed or started, it keeps for weeks, not months.

Unmixed vials

Fridge. Mix only when you are ready to start the vial.

Mixed vials

Fridge, good for around 6–8 weeks. Tesamorelin about 3 weeks.

Pens

Fridge, pre-mixed, around 6–8 weeks once started.

Volumes are our standard: 1ml bac water per 10mg up to 30mg, 2ml at 40mg, 3ml at 60mg and above. Blends are shown as the combined amount. A 1ml insulin syringe is 100 units; one pen click is 0.01ml.
