Description
References Jastreboff, A

Unit measurements at 7.5mg: 5mg/ml: 150 units (requires two injections) 10mg/ml: 75 units 20mg/ml: 37.5 units 40mg/ml: 18.75 units This dose level is where concentration choice starts to matter practically

So when you draw 50 units expecting 5 mg (from a 10 mg/mL vial), you might only be getting 4 mg or 3.5 mg

The B12 does not affect the tirzepatide concentration or your unit draw
