Buying Exosomes Wholesale for California Practices
Licensed California practices buy Kimera exosome material wholesale from ExaVeyra, for topical aesthetic use by licensed practitioners. Each practice account is checked against its California professional license and NPI, a review that takes 1 to 3 business days, after which material ships overnight on dry ice from Florida and reaches California in 1 to 3 business days, and the Certificate of Analysis for its lot is available on request. Public single-unit prices for Kiara and Vive appear in our catalog, while Luxir and Luxir+ are quoted after verification.
The nonresident wholesaler license is the supplier’s obligation, so a California practice buys without one. Compounded 503A preparations are not yet offered to California addresses, because our pharmacy partner’s California license is still pending.
California differs from most states in two respects worth knowing before you set up. Its stem cell law is a disclosure requirement rather than a permission, and it defines its subject by reference to the federal HCT/P category. Separately, California enforces the corporate practice of medicine doctrine more strictly than almost anywhere, so entity structure is decided early rather than late.

Ordering from California
ExaVeyra ships to licensed practices in all 50 states, California included. Licensure for shipping into the state is held by the entities that ship: our 503A pharmacy partner holds nonresident pharmacy licenses in 33 jurisdictions, including Puerto Rico, and exosome material ships from a registered tissue bank licensed to ship to all 50 states and Puerto Rico. Your practice orders against its own professional license and NPI and needs no wholesale permit to purchase.
What your practice provides
- An active California professional license in good standing, verifiable through the relevant board.
- A valid NPI, which ExaVeyra verifies at account setup.
- A signed professional-use acknowledgment on file for exosome material.
- A California resale certificate if the practice is purchasing for resale rather than for use in its own operations.
How the state permits wholesale distribution
California reaches further than most states here. Section 4161 treats anyone located outside California who ships, sells, mails, warehouses, distributes, or delivers dangerous drugs or dangerous devices into the state as a nonresident wholesaler, and requires a Board of Pharmacy license before doing so. Devices are inside the definition, where Florida for example requires no wholesale permit for devices. A separate license is required for each place of business, and the applicant maintains a valid license in its home state, with NABP Drug Distributor Accreditation available as an alternative route in some circumstances. The license sits with the distributor, not with the purchasing practice.
Cal. Bus. & Prof. Code § 4161 · California State Board of Pharmacy
California regenerative-medicine law
California enacted SB 512, codified at Cal. Bus. & Prof. Code § 684, effective 1 January 2018.
Health care practitioners licensed under division 2 of the Business and Professions Code who perform stem cell therapies not approved by the FDA. The required notice reads: “THIS NOTICE MUST BE PROVIDED TO YOU UNDER CALIFORNIA LAW. This health care practitioner performs one or more stem cell therapies that have not yet been approved by the United States Food and Drug Administration. You are encouraged to consult with your primary care physician prior to undergoing a stem cell therapy.” The section does not apply to a practitioner who has obtained FDA approval or clearance for an investigational new drug, or an investigational device exemption, for the use of HCT/Ps.
- Posted notice in the office entrance and a patient-visible area
- Written notice before the initial therapy
- Notice at least 8.5 by 11 inches in no less than 40-point type
“a therapy involving the use of HCT/Ps”
How this applies to exosomes
California is the clearest state in the country on this point, because section 684 defines its subject rather than leaving it to inference. It defines stem cell therapy as a therapy involving the use of HCT/Ps, the federal category of human cells, tissues, and cellular and tissue-based products regulated under 21 C.F.R. part 1271. Exosomes are acellular extracellular vesicles and are not HCT/Ps, so the section’s notice requirement is written around a category exosomes do not fall into. That is a statement about what the disclosure law covers, not a statement that exosome products sit outside regulation. They remain governed by federal law, under which no exosome product has been approved by the FDA for administration to humans. ExaVeyra supplies Kimera material for topical aesthetic use by licensed practitioners, with full COA and lot documentation.
Who can handle product in a California practice
California runs on two documents rather than a single standing protocol. An authorized clinician performs a good faith examination of the individual patient, then issues a patient-specific order; only after that order exists may a delegated provider administer the treatment within their own scope. Documenting both steps per patient is the practical difference between California and states that rely on a general standing delegation order.
| Role | Scope under state law |
|---|---|
| MD / DO | Physicians licensed by the Medical Board of California may perform medical acts within their scope and are the source of any delegation. Aesthetic procedures that constitute the practice of medicine sit inside that framework. |
| NP / APRN | Nurse practitioners may perform the good faith examination, issue patient-specific orders, and delegate to registered nurses within their scope. Assembly Bill 890 established pathways under which qualifying NPs may practice without standardized procedures, subject to the transition-to-practice and certification requirements the statute sets. |
| PA | Physician assistants practice under a practice agreement with a supervising physician and may perform the good faith examination within that agreement. |
| RN | Registered nurses may administer a treatment only after an authorized clinician has performed the good faith examination and issued a patient-specific order, and then only within the RN scope of practice. An RN does not perform the examination or set the treatment plan. |
Good faith examination
California treats the good faith examination as a baseline requirement before any delegated medical aesthetic procedure. The examining clinician assesses the patient, confirms the treatment is appropriate, and rules out contraindications. Only a physician, nurse practitioner, or physician assistant may perform it. A registered nurse may not, because the examination involves diagnosis and treatment planning that fall outside the RN scope. The examination may be conducted in person or by compliant synchronous telehealth.
Ownership and clinic licensing
Entity structure is decided early in California. The medical side of a practice is owned and controlled by licensed clinicians rather than by investors or a lay company, and it takes the form of a professional corporation rather than an LLC. Under the Moscone-Knox Professional Corporation Act a physician holds at least 51 percent of a professional medical corporation and a nurse practitioner may hold no more than 49 percent. Practices commonly pair the professional corporation with a separate management services organization. Assembly Bill 890 created a pathway for qualifying nurse practitioners to practice without standardized procedures and to form their own professional nursing entity, but it did not change the ownership ceiling inside a professional medical corporation. Structure this with California counsel.
Cold chain into California
Shipments leave Florida frozen under validated temperature monitoring. A package in transit over a weekend waits in the carrier network, so practices in California order around weekend and holiday closures.
| Metro | County | Notes |
|---|---|---|
| Los Angeles | Los Angeles | Largest aesthetic market in the country, with dense dermatology and med spa coverage. |
| Orange County | Orange | Newport Beach and Irvine corridor with a high concentration of aesthetic practices. |
| San Diego | San Diego | Strong regenerative and longevity segment alongside aesthetics. |
| San Francisco | San Francisco | Bay Area concierge and longevity practices. |
| San Jose | Santa Clara | South Bay market serving the Silicon Valley corridor. |
| Sacramento | Sacramento | Central Valley hub with a growing aesthetic segment. |

Federal and California rules for an order
- Federal
- No exosome product is FDA-approved, as the FDA's public safety notification on exosome products states. ExaVeyra supplies exosome material for topical aesthetic use by licensed practitioners.
- California
- The Medical Board of California requires a business offering cosmetic medical services to be owned by a physician or by a professional medical corporation with a physician as majority shareholder. It cites Business and Professions Code sections 2052 and 2400.
- Registered nurses and physician assistants may perform those services under physician supervision. A nurse practitioner furnishes drugs under a standardized procedure with a supervising physician (section 2836.1). One certified under section 2837.103, in a group setting with a physician, or section 2837.104, working independently, needs no standardized procedure.
- Practitioner licenses are confirmed through the Department of Consumer Affairs license search before a first order ships.

California sourcing questions
- Can a California clinic buy exosomes wholesale?
- Yes. A licensed California practice can buy Kimera exosome material wholesale from ExaVeyra, for topical aesthetic use by licensed practitioners. Purchases run through a practice account tied to the practice’s own California license and NPI, reviewed in 1 to 3 business days, and the practice holds no wholesaler license itself.
- What does a California practice need to open an exosome supply account?
- An active California professional license, a valid NPI and a signed professional-use acknowledgment, plus a California resale certificate if the practice buys for resale. Submit them through the online application; review takes 1 to 3 business days, and frozen material then reaches California in 1 to 3 business days by overnight shipping.
- How are exosomes priced for California practices?
- The catalog lists public single-unit prices for Kiara and Vive. Luxir and Luxir+ are priced on request, and a verified practice account sees wholesale pricing for the full range once its NPI has been confirmed.
- Does California’s stem cell disclosure law apply to exosomes?
- Section 684 of the Business and Professions Code defines stem cell therapy as a therapy involving the use of HCT/Ps, the federal category of human cells, tissues, and cellular and tissue-based products under 21 C.F.R. part 1271. Exosomes are acellular and are not HCT/Ps, so the notice requirement is written around a category they do not fall into. Exosome products remain governed by federal law, and no exosome product is FDA-approved for administration to humans.
- Who can perform the good faith exam in California?
- A physician, nurse practitioner, or physician assistant. A registered nurse may not, because the examination involves diagnosis and treatment planning outside the RN scope. Once the examining clinician issues a patient-specific order, a registered nurse may administer the treatment within their own scope. The examination may be in person or by compliant synchronous telehealth.
- Can a non-physician own a med spa in California?
- The medical side is owned and controlled by licensed clinicians through a professional corporation rather than an LLC. Under the Moscone-Knox Professional Corporation Act a physician holds at least 51 percent of a professional medical corporation and a nurse practitioner may hold no more than 49 percent. Practices commonly pair the professional corporation with a separate management services organization. Structure this with California counsel.
- Does my California clinic need a wholesaler license to buy exosomes?
- No. The nonresident wholesaler license under section 4161 is held by the out-of-state distributor shipping into California, not by the practice buying. Your practice orders against its own professional license and NPI. Licensure for shipping into the state is held by the entities that ship: our 503A pharmacy partner for compounded preparations, and a registered tissue bank licensed to ship to all 50 states and Puerto Rico for exosome material.
- How is California’s wholesaler rule different from other states?
- It is broader. Section 4161 reaches dangerous drugs and dangerous devices, and requires a separate license for each place of business a distributor ships from. Florida, by contrast, requires no wholesale distributor permit for devices at all. This affects which suppliers can lawfully ship into California, which is worth confirming with any vendor you use.
- How long does cold-chain shipping take to California?
- Ships from Florida by overnight shipping, and arrival can take one to three business days. All exosome shipments travel cold-chain with validated temperature monitoring. A shipment in transit over a weekend waits in the carrier network, so a practice that will be closed orders around the closure.
