Adding a me-too, because a thread of one person's experience is not much use. Nothing to add that would improve it.

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.

Comparison of compounded dosing arithmetic delivery formats I've tried:

FormatProsCons
Lyophilized vialLongest shelf life, lowest costRequires reconstitution
Pre-mixed vialReady to draw upShorter shelf life (28-45 days)
Pre-filled syringesMost convenientHigher cost, shorter shelf life
Sublingual dropsNo needlesLower bioavailability, less data

I use lyophilized vials for cost and stability. The reconstitution takes 30 seconds once you've done it a few times.

Following on from NurseKim_ATL — and this may be the naive question:

What did you change at the same time, and can you separate the two now?

Reporting back.

Went back through my own correspondence with an earlier supplier and the warning signs were all there in the replies, weeks before the quality changed. I was reading the product and not the behaviour.
