EP. 260: Join my NEW community for Gen X women: ⁠https://www.skool.com/drtyna/about⁠
In this episode, I walk through the current state of GLP-1 medications and peptides, including what is changing with compounded access, recent FDA actions, and the shifting roles of 503A and 503B pharmacies. I break down what this means in practical terms for patients and clinicians as availability continues to evolve and brand name pathways become more prominent.
I also cover the broader peptide landscape, including regulatory uncertainty, dosing and safety concerns, and why there is so much confusion in the space right now.
Topics Discussed:
→ What is happening with peptides now?
→ Are peptides safe?
→ Are compounded GLP-1s ending?
→ What is 503A vs 503B?
→ Why are GLP-1s changing?
