Quezon City is geographically enormous and a courier crossing it is not doing a Makati run. Diliman to Eastwood, or Tomas Morato to the Katipunan stretch, can eat an afternoon on its own, and a delivery originating outside the city adds that leg on top of everything else. Readers in the southern districts consistently underestimate this.
MOTS-c happens to be the compound least bothered by it. The vial ships as sealed lyophilized powder and dry material tolerates a long, warm afternoon far better than anything reconstituted or shipped in solution. If you are in Katipunan and the parcel takes until evening, you have lost time, not material.
Housing here is mixed enough that the handoff varies more than in any other district. Condo stock along Katipunan and in Eastwood behaves like the rest of the metro, with a desk that logs and holds. Older subdivision housing in the Diliman surrounds and around Tomas Morato often has no desk at all, which means a phone call and a gate. Neither is a problem for a dry vial. Both are worth anticipating so the rider is not standing outside at six in the evening.
