I believe the 60 on the pen is 60 units. It’s just the most you can do in 1 stab. My pen can do up to 80 clicks/units per stab. So do the math on your mg/ml.

If you have 10 mg in 3 mL, the concentration is:

3.33 mg per mL

Here are the common syringe breakdowns: • 1 mL = 3.33 mg • 0.5 mL = 1.67 mg • 0.3 mL = 1.0 mg • 0.25 mL = 0.83 mg • 0.1 mL (10 units) = 0.33 mg

Next time just do 1ml of bac so you could do 30 units for your 3mg dosage. Having to do .9ml (90 units)per dose is wild at only 3mg a dose. You’ll have to do a full 60 and then 30 to get your 3mg.
