I have 20 units left of a vial of ProRX. I just got a shipment of Apothecary. Tomorrow is shot day and I have 2 vials of ProRX with a BUD in 2027. The apothecary vials have a BUD of October 2026.
I will need to draw 36 units from a new vial to make a full dose and I want to do so from Apothecary because of the BUD.
I will use separate needles, but I’m wondering if anyone has “mixed” 2 different pharmacy Tirz without incident.
EDIT: I pulled from both vials today. The Apothecary burned a tiny bit going in, but no site reaction. I also did not use a vial opener. I may have left 1-1.5 units behind, but that's not enough for me to go crazy. I'll make another post if things seem "off" this week. Even though it's all anecdotal, I like to share experiences.
