What dosage would this be?

I know this may be more appropriate for a pharmacy sub but I couldn't fine one to ask this in.

I'm supposed to be on a 2.4mg dose of semaglutide. My last refill came from a different compounding pharmacy and at a different concentration than usual, so I looked at it more closely than I normally would.

This doesn't seem correct to me, based on math.

Here are the details from the prescription packaging:

"Semaglutide/Cyanocobalamin (2.5ML) 5/.5 MG/ML injectable

Inject 41 units subcutaneously (under the skin) once weekly"

The syringes are 100cc/1ML.

Is this not 4.1mg as instructed, not 2.4mg I'm prescribed? Or am I missing something?

I have already reached out to the prescriber and am awaiting response because I also can no longer see my prescribed dose in the online portal.
