What payment methods do you accept?
Zechu Labs offers a variety of secure payment options at checkout, including digital and traditional methods. Due to the research-chemical classification of peptides, many mainstream payment processors restrict transactions in this space — so available methods may evolve over time as we expand our payment partnerships. All transactions are processed through encrypted, PCI-compliant gateways to protect your information. Specific payment options will be displayed during the checkout process.
How should peptides be stored?
Storage requirements vary by compound. Most research peptides require storage in a cool, dry environment away from direct light. For specific storage parameters for your research application, please consult published scientific literature and product documentation.
