Accidentally used a U40 syringe instead of U100, did I mess up?

hey everyone, kinda stressing and hoping someone with more experience can weigh in.

so for the past 4 weeks, i’ve been pinning 20 units daily of a peptide using a u100 syringe. my setup: 10 mg vial reconstituted with 1 ml bacteriostatic water.

today(week 5) i was in a rush and didn’t realize until after that i used a u40 syringe instead instead, still drew up to 20 units like i normally do.

from what i understand, it’s 5mg in my system now.

also wondering about something else. if i go back to my normal dosage from next week, will it still work the same or does messing up one dose affect how my body responds?

appreciate any insight 🙏
