Compounded peptide reconstitution water — looking for input

There is a second half to this that has not been said yet. The shortage clause is the answer to the second question and it is a subtraction rather than an addition. Both exemptions forbid compounding something that is essentially a copy of a commercially available approved product. A product FDA has listed as in shortage is not treated as commercially available, so listing removed the objection that otherwise blocked compounding. It never created a permission; it withdrew a prohibition, which is why it evaporated the moment the supply fact changed.

Ongoing cost tracking for dosing arithmetic — transparency for the community:

Monthly medication cost: $119
Supplies (syringes, BAC water, alcohol swabs): ~$12/month
Janoshik testing: ~$14/month (amortized quarterly)
Lab work: ~$59/month (amortized quarterly)
Total: ~$219/month

Compare to brand Wegovy at $1359/month without insurance. Compounded is roughly 88% cheaper for what I have found to be clinically equivalent medication.

Following on from Dr.SurgeonPGH — and this may be the naive question:

What actually distinguishes 503A from 503B, in terms of what each may make and from what starting material?

dosing arithmetic — critical reminder about tirzepatide dose equivalence across formulations:

Mounjaro KwikPen and compounded tirzepatide are the same molecule but:

• KwikPen is ready to inject, no mixing needed
• Compounded requires reconstitution and proper syringe technique
• Verify your compounded concentration before each injection
• Never assume 1 vial = 1 dose without checking the math

OP back with an update, since a thread like this is useless without one.

The bulks-list asymmetry was the piece I had missed entirely. It explains why one of my two pharmacies is still arguing it can supply and the other simply stopped.
