Our office is in Highland Park Village, but the mailing address reads Dallas. Which town's rules apply?

The town the building sits in decides, not the city printed on the label. Highland Park Village stands at Mockingbird Lane and Preston Road inside the Town of Highland Park, so the town's building inspector issues the suite's certificate of occupancy and compliance. Tell us the municipality when you add the address, and we record it on the account alongside the suite number and the person who will sign.

An ice storm warning is posted for Dallas County. What happens to an order already on its way?

Once placed, an order is not held back, so a Dallas practice that expects to shut for ice should hold off ordering until it is open again. For a package already on the road, we watch the tracking and call your named recipient. If an iced-in package reaches your Dallas office and its dry ice has fully sublimated, we send a replacement. Delays of any other kind are reviewed for a refund, which turns on whether the material was kept temperature-controlled the whole way.

Our group has one suite in Uptown Dallas and another in Plano. Can both sit on one account?

Yes. Both addresses are on the Texas lane, so the transit window is the same, and each lot is tied to the suite that signed for it. The difference is local: the Uptown suite falls under Dallas County emergency management and a City of Dallas certificate of occupancy, while a Plano suite sits in Collin or Denton County, so the two sites can hear from different county emergency offices during the same ice storm.

Exosome supply for Dallas and Highland Park practices

A licensed practice in Dallas, Highland Park or University Park that holds a verified wholesale account receives biomolecular signaling vesicles (exosomes) frozen from Florida, carried on the Texas lane. Dallas County prescribers may also write individual prescriptions for our 503A pharmacy partner to compound, dispense and send out from Texas.

When an order reaches a Dallas or Highland Park practice

A Dallas order travels frozen from Florida on the Texas carrier lane and arrives inside the transit window in the panel above. Prescriptions sent to our pharmacy partner follow their own path: it compounds each preparation, then dispenses it and sends it out from Texas to the clinic or the patient, with shipping options that differ from one formulation to the next.

Ice is the local event that has stopped road and air traffic in Dallas in recent winters. During the sleet and ice event of 30 January to 1 February 2023, the National Weather Service counted several hundred crashes on icy North Texas roads, and DFW Airport logged 3,544 flight cancellations, with 982 more at Dallas Love Field. In February 2021, DFW stayed at or below freezing for 139 consecutive hours and reached -2°F on 16 February.

An ice closure does not pause an order that has already been placed. A package already moving stays with the carrier until the roads clear; in 2023, DFW did not climb above freezing until late morning on 2 February. A Dallas practice that sees a winter storm warning for Dallas County should place its order once staff can reach the office and accept a delivery.

Cold-chain receiving at a Dallas or Highland Park address

Heat is the receiving risk for the rest of the year. National Weather Service normals put DFW Airport at 95.6°F in July and 95.8°F in August, with about 20 days a year at 100°F or more, so a shipper left on a Dallas loading dock through an afternoon uses up its dry ice quickly.

The USPS lookup gives Dallas as the city name for ZIP code 75205 and marks Highland Park and University Park as names it does not accept, yet University Park's own city hall sits in that ZIP. The account therefore records the town the suite actually sits in, a named recipient and that person's working hours. When the box comes in, the recipient checks for remaining dry ice, logs the time it landed and its lot number, and transfers the vials to a freezer. Under the manufacturer's handling instructions, vials are kept at -20°C for extended storage and at 4°C once they have thawed.

Rules that apply to a Dallas or Highland Park order

The City of Dallas requires a certificate of occupancy before a building or suite is used, and a new one whenever the tenant changes. A practice taking over a Dallas suite should hold its own certificate before that address goes on the account.
Highland Park and University Park are separate municipalities surrounded by Dallas, and each issues its own certificate. Highland Park's zoning ordinance bars use of a converted or altered building until its building inspector issues a certificate of occupancy and compliance. University Park's application must include a floor plan of the space.
Dallas County Homeland Security and Emergency Management runs a county-wide emergency management program, which under state law must serve the entire county, Highland Park and University Park included.

Federal and Texas rules for an order

Areas near Dallas and Highland Park on the same lane

University Park and Plano share the Texas lane and transit window with Dallas, and one account can list a suite in each, with every lot logged to the suite that took delivery. University Park is its own city with its own certificate of occupancy process but sits wholly in Dallas County, so the same county emergency program covers it. Plano, about 20 miles north of Downtown Dallas, lies in Collin and Denton counties, so a Plano suite answers to a different county emergency program than a suite in Dallas County.
