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 and 503A patient-specific compounds — at pricing no individual practice can negotiate alone. We only work with licensed physicians — we don't sell to the public.
FDA Enforcement Notice: Wholesale distribution of compounded drugs through brokers or middlemen violates FDCA §503B. Compliant sourcing means 503B outsourcing facilities and licensed 503A pharmacies — direct to the practitioner, never through brokers.
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 two compliant facility types — 503B outsourcing facilities and licensed 503A pharmacies — and only a GPO gives you structured access to both at network pricing. All sterile injectable products in our network are independently verified and documented to the highest standards in the industry. Every supplier in the Sereno GPO network sells direct to licensed physicians and practices — no middlemen, brokers, or wholesalers participate in the process.
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.
No two member practices order the same formulary. Sereno GPO reviews your specialty, patient volume, and clinical use cases, then builds a formulary tailored to what your practice actually needs — sourced through the compliant pathway appropriate for each category, at network pricing no individual practice can negotiate alone.
We don't publish a public catalog — we build a curated formulary for each practice. Formulary access and pricing are member-gated and specific to your practice. Don't see something you need? We can get it for you. Just ask!
Most practices are unfamiliar with the regulatory distinctions that govern compliant compounding. Here is what each term means and why it matters for your practice.
Compliance is the foundation. Growth is the goal. Through Sereno MSO, GPO members access a full suite of clinical education tools, practice management, and marketing services designed specifically for longevity medicine practices.
Both pathways lead to the same place — a compliant, well-priced, growing longevity medicine practice backed by the Sereno GPO and MSO network.
