We evaluate suppliers based on:
When available from suppliers, documentation may include:
Note: Documentation availability varies by supplier and product. We provide what is available and transparently note when documentation is limited. All products are intended for laboratory research use only.
Overseas options are direct-sourced from manufacturers, avoiding middleman markups. You accept a longer shipping timeline (2–3 weeks) instead of paying for fast logistics and US warehouse inventory. This creates significant cost savings.
Overseas sourcing includes synthesis time (5–7 days), international courier shipping (7–10 days), and customs clearance. We provide full tracking throughout. The timeline is predictable but longer than domestic inventory.
Domestic pricing reflects the cost of maintaining US inventory, inventory risk, temperature-controlled storage, and fast dispatch logistics. You pay a premium for convenience and predictable 2–5 day delivery.
Both sourcing paths use suppliers we've screened. The key difference is sourcing method and timeline, not quality. Documentation availability may vary by supplier, and we're transparent about what's available for each product.
Documentation availability depends on what our suppliers provide. We include available batch documentation with orders. Not all suppliers provide complete COAs, and we're transparent about documentation limitations.
