I’m going from BPI to apothecary . I have about 60 units left of a vial from BPI. Can I use what I have left and supplement the rest with apothecary? I messaged the doctor but haven’t heard back. I normally do 90 units or the BPI with the additive. Since apothecary is just tirz I’m not sure how it works. Thank you.
