The only Group Purchasing Organization built exclusively for longevity medicine practices — giving physician clinics, med spas, and wellness centers direct access to USA-made, batch-tested 503B outsourcing facility products, 503A patient-specific compounds, and USP <797>-compliant sterile preparations at pricing no individual practice can negotiate alone.
FDA Enforcement Notice: Wholesale distribution of compounded drugs through brokers or middlemen violates FDCA §503B. Compliant sourcing means 503B outsourcing facilities, licensed 503A pharmacies, and USP <797>-compliant sterile compounders — direct to the practitioner. Sereno GPO connects you to all three.
Sereno GPO is not a vendor. It is a Group Purchasing Organization that aggregates buying power across a national network of practices — giving every member access to FDA-compliant products, legal structure, expert educators, and business support that would otherwise cost multiples more to assemble independently.
FDCA §503B prohibits compounded drugs from moving through brokers or resellers. There are three compliant sourcing pathways — 503B, 503A, and USP <797> — and only a GPO gives you structured access to all three at network pricing.
Legal basis: FDCA §503B · OIG GPO safe-harbor 42 C.F.R. §1001.952(j) · DSCSA 21 U.S.C. §360eee-1 · Structure reviewed by our healthcare regulatory counsel.
Why this matters for med spas: Your business operates under a supervising physician whose license is on the line for what gets administered under their delegation. Medical directors are walking away from practices that cannot document their supply chain. A med spa without a medical director is a med spa that is closed.
Why this matters for physician clinics: A defensible state board audit response requires a documented FDA-registered supplier, current DSCSA pedigree, a valid compounding pathway, and a written compliance framework. Penalties reach license suspension and FDA civil penalties up to $597,317 per violation.
The Sereno GPO formulary spans three compliant pathways: 503B outsourcing facilities for office-use bulk products, 503A licensed pharmacies for patient-specific prescriptions, and USP <797>-compliant sterile compounders for injectable preparations. Every product USA-manufactured, independently tested, Certificate of Analysis on every batch.
Most practices only know one pathway. Sereno GPO members access all three — matched to the right product, the right patient, and the right compliance framework every time.
Access to the right products means nothing without the clinical knowledge to deploy them effectively. Sereno GPO members receive direct access to our network of educators specializing in peptide therapy and hormone optimization — practitioners who translate complex science into safe, effective protocols for your team.
Compliance is the foundation. Growth is the goal. Through Sereno MSO, GPO members access a full suite of practice management and marketing services designed specifically for longevity medicine practices.
GLP-1 medications represent one of the largest and fastest-growing categories in longevity medicine — and one of the most administratively complex. Sereno GPO manages the prior authorization process so your team doesn't have to.
