Sourcing Exosomes in Washington
Licensed Washington practices order Kimera exosome material from ExaVeyra for topical aesthetic use, shipped frozen from Florida with lot traceability on every vial and a certificate of analysis issued for every lot and provided on request. Washington buyers need their own professional license and NPI; the nonresident pharmacy and wholesaler licenses the state issues sit with the entity that ships into the state rather than with the purchasing practice.
Two Washington points are worth settling early. The state has a stem cell notice law, RCW 18.130.420, whose definition is written around cells and tissues rather than acellular vesicles. And advanced registered nurse practitioners are licensed independent practitioners here, which gives a Washington practice two workable staffing models rather than one.

Ordering from Washington
ExaVeyra ships to licensed practices in all 50 states, Washington 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 changes state to state is how the state regulates who performs a procedure and what notices a practice must give, while federal law governs the product itself.
What your practice provides
- An active Washington professional license in good standing, verifiable through the Department of Health’s provider credential search.
- A valid NPI, which ExaVeyra verifies at account setup.
- A signed professional-use acknowledgment on file for exosome material.
- A Washington reseller permit from the Department of Revenue if the practice is purchasing for resale rather than for use in its own operations. Every business selling at wholesale must hold a copy of the buyer’s permit, so ExaVeyra asks for it at setup.
How the state permits wholesale distribution
Washington licenses out-of-state shippers on two tracks, both through the Pharmacy Quality Assurance Commission. RCW 18.64.360 defines a nonresident pharmacy as any pharmacy located outside the state that ships, mails or delivers controlled substances, legend drugs or devices into Washington; it must be licensed by the Department of Health, disclose its owners and dispensing pharmacists, designate a Washington resident agent, and submit an inspection report issued within two years of application or renewal. RCW 18.64.046 requires a wholesaler’s license of any person, in or outside Washington, who sells legend drugs and nonprescription drugs at wholesale to pharmacies and practitioners in the state. WAC 246-945-100 holds every commission licensee that compounds sterile or nonsterile preparations, for patient administration or for distribution to a licensed practitioner, to USP chapters 795, 797, 800 and 825. Each license sits with the supplier, not with the purchasing practice.

Washington regenerative-medicine law
Washington enacted HB 2356, codified at RCW 18.130.420, effective 7 June 2018.
License holders under the Uniform Disciplinary Act, chapter 18.130 RCW, which covers physicians, nurses and the other professions the Department of Health credentials. A practitioner performing a stem cell therapy not approved by the FDA must give the patient a written notice in the statutory wording before the therapy, display it prominently at the entrance and in an area visible to patients, and carry it in advertisements in a font no smaller than the largest font used. Practitioners working under an FDA investigational approval or under qualifying institutional arrangements are excepted, and a violation is unprofessional conduct.
- Written notice to the patient before an unapproved stem cell therapy
- Notice displayed at the entrance and in a patient-visible area
- Notice at least 8.5 by 11 inches in no less than 40-point type
- Notice carried in advertising for the therapy
“a therapy involving the use of human cells, tissues, or cellular or tissue-based products”
How this applies to exosomes
Washington’s notice law is often read as reaching exosomes. Its definition of stem cell therapy is a therapy involving the use of human cells, tissues, or cellular or tissue-based products. Exosomes are acellular extracellular vesicles rather than cells or tissue, and the statute does not address them either to require the notice or to excuse it. Exosome products remain governed by federal law, under which no exosome product has been approved by the FDA for administration to humans. Whether a particular service falls inside the notice requirement is a question for the practice and its counsel, and the Washington Medical Commission is the body that interprets it for physicians. ExaVeyra supplies Kimera material for topical aesthetic use by licensed practitioners, with lot documentation and a certificate of analysis for every lot.
Who can handle product in a Washington practice
Washington runs on two models. A physician-led practice delegates nonsurgical cosmetic procedures under WAC 246-919-606, which requires the delegating physician to be trained in the procedure, a written office protocol naming the responsible physician and the patient selection criteria, a signed patient consent that identifies the delegate, and documentation of each treatment in the patient’s record. An ARNP-led practice orders and supervises within nursing scope on its own authority. Either way, the Department of Health’s guidance places responsibility for keeping every person inside their legal scope on the medical director or supervisor.
| Role | Scope under state law |
|---|---|
| MD / DO | Physicians licensed by the Washington Medical Commission perform medical acts within their scope and are the source of any delegation. Under WAC 246-919-606 a physician who is trained in a nonsurgical medical cosmetic procedure may delegate it to a properly trained physician assistant, registered nurse or licensed practical nurse under a written office protocol, and remains responsible for the patient’s safety regardless of who performs it. |
| NP / APRN | Advanced registered nurse practitioners are licensed independent practitioners under WAC 246-840-300: they examine patients, establish diagnoses, manage treatment plans and prescribe within their certification, with no physician supervision requirement. That is what allows an ARNP-led aesthetic practice in Washington to operate without a physician medical director for services inside ARNP scope. |
| PA | Physician assistants practice under a written collaboration agreement with one or more physicians under RCW 18.71A.030. A PA with fewer than 4,000 hours of postgraduate clinical practice works under physician supervision; one with 4,000 or more hours, including 2,000 supervised hours in the chosen specialty, may work in collaboration. |
| RN | Registered nurses execute a medical regimen prescribed by an authorized practitioner under RCW 18.79.260. The Board of Nursing’s published answer is that a competent, appropriately trained RN may administer cosmetic injectables on a prescription from an authorized practitioner, that the nursing rules do not require the practitioner to be on the premises, and that the RN should follow the Medical Commission’s delegation rule, which the Board describes as asking the delegating physician to be reachable within thirty minutes. |
Good faith examination
Washington does not use the phrase “good faith examination” in statute or rule. The functional requirement sits in the delegation rule: a physician-led practice’s written office protocol must include selection criteria to screen patients for the appropriateness of treatment, the physician must be trained in the procedure, and each treatment is documented in the patient’s medical record. An ARNP may perform the examination and set the plan within their own scope. Confirm current expectations with the Washington Medical Commission and the Washington State Board of Nursing.
Ownership and clinic licensing
Washington has no statute expressly prohibiting the corporate practice of medicine; the doctrine rests on case law, and the Department of Health’s own guidance for businesses offering esthetic services lists it among the legal issues to consider, alongside fee-splitting, rebating and aiding unlicensed practice, and recommends counsel. Advanced registered nurse practitioners hold independent practice authority, so an ARNP-led practice can operate within nursing scope, while a physician-led practice runs on physician delegation. Structure the entity with Washington counsel before opening.
Cold chain into Washington
Shipments leave Florida frozen under validated temperature monitoring. A package in transit over a weekend waits in the carrier network, so practices in Washington order around weekend and holiday closures.
| Metro | County | Notes |
|---|---|---|
| Seattle | King | Highest concentration of aesthetic, dermatology and concierge practices in the state. |
| Bellevue | King | Eastside corridor with a dense med spa and longevity market. |
| Tacoma | Pierce | South Sound market with a broad clinical mix. |
| Spokane | Spokane | Eastern Washington hub serving the Inland Northwest. |
| Vancouver | Clark | Southwest Washington practices on the Portland metro border. |
| Everett | Snohomish | North Puget Sound market with growing aesthetic coverage. |
- Washington orders of fifteen or more cold-chain units ship free nationwide; see the volume program for current thresholds.

Washington sourcing questions
- Does Washington’s stem cell notice law apply to exosomes?
- RCW 18.130.420 defines stem cell therapy as a therapy involving the use of human cells, tissues, or cellular or tissue-based products, and requires a written and displayed notice before a practitioner performs one that the FDA has not approved. Exosomes are acellular and the statute does not name them, so it neither requires the notice for them nor excuses it. Exosome products are governed federally, and no exosome product is FDA-approved for administration to humans. Whether a given service falls inside the notice requirement is a question for your counsel and the Washington Medical Commission.
- Does my Washington clinic need a nonresident pharmacy or wholesaler license to buy exosomes?
- No. Both licenses sit with the entity that ships into the state shipping into Washington: the nonresident pharmacy license under RCW 18.64.360 and the wholesaler license under RCW 18.64.046. Your practice orders against its own professional license and NPI, and ExaVeyra confirms destination licensure across its supply chain before a first order ships.
- Can my Washington practice source 503A compounded peptides through ExaVeyra?
- Yes. Compounded formulations are prepared by our 503A pharmacy partner, a compounding pharmacy licensed by the Texas State Board of Pharmacy, and it holds the Washington nonresident pharmacy license that RCW 18.64.360 requires of an out-of-state pharmacy shipping into the state. That license carries an inspection report issued within two years of application or renewal and, for a pharmacy that compounds, the USP standards of WAC 246-945-100. It sits with the pharmacy rather than with your practice; the Pharmacy Quality Assurance Commission’s public records are where a practice confirms it, and we confirm current status for your destination before the first prescription is placed.
- What does ExaVeyra verify before opening a Washington account?
- An active Washington professional license checked against the Department of Health’s provider credential search, a valid NPI, and a signed professional-use acknowledgment for exosome material. Practices buying for resale also provide a Washington reseller permit, which the Department of Revenue requires every wholesale seller to hold a copy of.
- Who in a Washington practice can handle exosome material?
- Physicians licensed by the Washington Medical Commission act within their scope and may delegate nonsurgical cosmetic procedures to a trained PA, RN or LPN under WAC 246-919-606, with a written office protocol and a signed consent that identifies the delegate. Advanced registered nurse practitioners are licensed independent practitioners and act within their own scope. Registered nurses execute a regimen prescribed by an authorized practitioner. Confirm your own protocols with Washington counsel.
- Can a nurse practitioner run an aesthetic practice in Washington?
- Within nursing scope, yes. WAC 246-840-300 describes the ARNP as a licensed independent practitioner who examines, diagnoses, manages treatment plans and prescribes, so an ARNP-led practice does not need a physician medical director for services inside ARNP scope. Ownership structure is a separate question the Department of Health’s guidance flags for counsel, since the corporate practice doctrine in Washington rests on case law.
- How should exosome material be handled on arrival?
- Check the temperature indicator included with the shipment before the vials go into storage, and move them to their storage condition promptly. If the indicator reads outside range, contact us before use rather than storing the shipment. Storage and handling conditions follow the manufacturer's handling instructions, which ship with each order, and every vial carries its lot number.
