Already know the material? Pass this checkpoint without opening the lesson first.

Get every question correct to pass.

1. A cell study shows GHK-Cu increases collagen-related activity. What does that establish most directly?

A mechanistic signal under the study conditionsGuaranteed wrinkle reduction in every productA validated injectable protocolProven hair regrowth in humans

2. Why can't topical evidence be transferred automatically to injectable GHK-Cu?

Route, exposure, safety and formulation are differentThe molecule changes its nameTopical studies are always stronger than randomized trialsInjectable routes never matter

3. What is the correct interpretation of a patient-reported improvement when objective measures do not differ?

It is an interesting subjective signal that should not overwrite the objective findingsIt proves the objective measures were wrongIt establishes every cosmetic claimIt should be ignored completely

4. Which phrase best summarizes GHK-Cu evidence?

Promising biology, some topical human evidence, major formulation dependenceClinically proven for every routeNo evidence of any kindApproved injectable therapy

5. What question should come before comparing two GHK-Cu products?

Do they deliver comparable formulation, concentration and exposure?Do they use the same bottle colour?Which has the longest benefit list?Which has the highest price?
