Beyond-use dating (BUD) for compounded supply compounded products: Lyophilized (unreconstituted): typically 6 months from compounding date…

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 $161/month vs $1,231 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.

Bookmarking. The distinction being drawn above is the one nobody else makes. Adding it to my notes with a link back to this thread.

Vendor communication red flags for compounded supply:

  • Won't provide COA before purchase — walk away
  • Claims "100% pure" without analytical data — unrealistic
  • No physical address or phone number — accountability matters
  • Pushes you to buy more than you need — pressure tactics
  • Won't answer questions about their compounding process — transparency is key
  • Payment only via crypto or wire transfer — legitimate pharmacies accept cards

A legitimate compounding pharmacy operates like a healthcare business, not a gray market dealer.

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

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 still in shortage, tirzepatide removed from shortage list. This directly impacts compounding availability.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. No action needed from anybody.
