규격 선택이 공급업체 선택보다도 중요합니다. 코폴피드 (GHK-CU) 카테고리에서는 현재 플랫폼에서 40개의 목록이 38개의 다른 규격으로 제공되고 있습니다. 이 표는 각 일반적으로 제공되는 규격과 실제로 발행된 단가를 비교하여, 어떤 차이가 화장품에 영향을 미치고 어떤 차이가 비용을 변경하는지 확인할 수 있습니다.

Prices are the published unit prices in US dollars for the listed specification. Where a specification appears with a wide range, the spread almost always reflects pack size, concentration or the unit of sale rather than a pure price difference — open the individual listings before drawing a conclusion.
What to check before you order
Confirm the unit. The same specification may be sold per vial, per box, per pair or per set. Convert every quotation to a single unit before comparing.
Fix the concentration or fill. Where a specification lists options (for example two fill weights), state in writing which one your order refers to — this is the single most common source of a shipment that technically matches the product name but not the purchase order.
Ask for the documentation. A certificate of analysis and test report tied to the lot number is what lets you verify conformance on arrival.
Sample a new specification. If you are moving to a specification you have not bought before, order a sample lot first; the cost is small relative to the risk of a production quantity that cannot be used.
Selection logic that generally holds
For a first order, the lowest price is rarely the correct basis for a decision. A mid-range specification from a supplier who can state a consistent fill weight, provide documentation and hold the specification over repeat orders is normally the lower-risk choice, and it usually turns out cheaper once rework, claims or a failed batch are priced in. Reserve the lowest-priced small-pack listings for trial quantities where you are buying specifically to evaluate, not to consume.
