One thing that is still open after jim_asheville’s answer:

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

Resolution therefore closed the doors unevenly, and the asymmetry follows from the bulks lists.

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

Monthly medication cost: $156
Supplies (syringes, BAC water, alcohol swabs): ~$9/month
Janoshik testing: ~$11/month (amortized quarterly)
Lab work: ~$56/month (amortized quarterly)
Total: ~$226/month

Compare to brand Wegovy at $1396/month without insurance. Compounded is roughly 85% cheaper for what I have found to be clinically equivalent medication.

Sharing my dosing arithmetic titration experience with compounded semaglutide — I have been tracking injection volumes meticulously:

Using 5mg/2mL concentration with 1cc insulin syringes:

• Month 1: 10 units (0.25mg) — mild appetite reduction
• Month 2: 20 units (0.5mg) — significant appetite suppression
• Month 3: 30 units (0.75mg) — custom intermediate dose
• Month 4: 40 units (1.0mg) — optimal for me, staying here

The beauty of compounded vials is you can do custom intermediate doses. My provider was great about tailoring to my response.

That reframing is the part I needed. Sending this to two other people who asked me the same thing last week.

Adding the clinical framing, because it changes how the question reads.

Just received my dosing arithmetic order — packaging review:

• Outer box: plain brown, no medication identifiers (discreet) ✅
• Inner insulation: Styrofoam with 4 gel ice packs ✅
• Temperature: vials were cold to touch on arrival ✅
• Labeling: lot number, BUD, compound name, concentration ✅
• Included: COA, reconstitution instructions, dosing card ✅

This is what professional compounding pharmacy shipping looks like. If your order arrives without these basics, reconsider your vendor.
