RegAffairsDC — wow. This community is amazing.

Thanks for sharing this, RegAffairsDC. A few questions about your FDA compounding experience:

1. What dose did you start at?
2. How long before you noticed side effects improving?
3. Did your provider have any specific recommendations about FDA compounding?

I am in a similar boat and trying to learn from others' experiences before my next appointment.

Clinical perspective on FDA compounding enforcement update :

I have managed roughly 300 patients on GLP-1 therapy and this topic comes up frequently. What the data shows — and what I see in practice — is that the medication works best as part of a comprehensive approach.

For this specific question, I would recommend: getting comprehensive baseline labs first.

OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on FDA compounding.

To answer TinaHashiRN: yes, I am on compounded sema from a 503B pharmacy.

Quick update: things are still going well. Thanks again for the evidence-based discussion — this is exactly why I posted in a science-based community. 🙏
