Returns & Exchanges
At WHC LAB, we prioritize the quality and safety of our fermentation products; therefore, we offer returns on unopened, shelf-stable items within 14 days of delivery. Due to the perishable nature of live yeast cultures, specialized handling is required to ensure product integrity during the return process.
