Your timeline is unclear, but it's absolutely essential that you learn from that holistic practice what your weekly doses have been. It could be 10mg/week, or it could be that the 10mg vial they gave you for 4 weeks of draws is a 2.5mg weekly dose.
The standard protocol for tirzepatide is (assuming no intolerable side effects along the way, at which point you'd drop back down a step) is 4 weeks at 2.5mg/wk, 4 weeks at 5mg, then similarly every fourth week a 2.5mg increase in the weekly dose until you hit 15mg.
I'm guessing you've been at 2.5mg/wk and then were increased to 5mg/wk.
If you really can't get a clear written answer from the medical practice, proceed as if you've never used tirz and start the standard protocol from 2.5mg/wk as above.
