503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously: Feature 503A 503B Regulation State Board of Pharmacy…

Regarding compounded supply compounding legality: compounding pharmacies can legally produce semaglutide and tirzepatide while these drugs remain on the FDA shortage list. If/when the shortage resolves, the legal landscape may change.

Stay informed. The FDA shortage list is updated regularly. Current status as of my last check: semaglutide shortage ongoing, tirzepatide partially resolved. This directly impacts compounding availability.

Genuinely useful, thank you. I had the facts and not the framework. Adding it to my notes with a link back to this thread.

Price comparison for compounded supply across sources I've used:

I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.

My pharmacy stopped supplying with three weeks notice and a letter that explained nothing, so I went and read the statute.

Compounding pharmacy customer here with experience relevant to compounded supply.

I've ordered from 2 different compounding pharmacies over the past 2 years. The quality variation is real — purity ranged from 94% to 101% of label claim based on independent Janoshik testing.

My current compounder (a 503B facility) has been consistently 98-101% purity across 10 orders. I pay $137/month vs $1,267 for brand. The savings are substantial and the product is equivalent in my experience.

Re: compounded supply — this applies whether you're using brand or compounded. The clinical principles are the same.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. Carry on.
