— FAQ
You ask,
we answer.
Still have a question? Our team responds to research inquiries within one business day.
Contact our teamDo you provide instructions?
No. MOB Biotech does not provide reconstitution, dosing, or usage instructions. All products are designated for Research Use Only (RUO). Requests for use-related guidance cannot be accommodated.
When do you ship?
Orders are processed Monday through Friday, excluding holidays. Shipping methods and costs are calculated at checkout. Expedited shipping options may be available upon request.
How can I make sure the product I received is high quality?
We provide batch-specific certificates of analysis (COA) for all products. These documents report analytical testing results relevant to research verification and quality assessment.
What are peptides?
Peptides are short chains of amino acids studied in laboratory research for their chemical and structural properties. MOB Biotech supplies peptides strictly as research reagents for in-vitro and laboratory investigation. No biological, medical, or therapeutic claims are made.
What does lyophilized mean?
Lyophilization (freeze-drying) is a laboratory process used to remove moisture from chemical compounds for stability during storage and transport. This process is commonly used in research settings and does not imply suitability for human or veterinary use.
What is your return policy?
Due to the nature of research reagents, returns are not accepted for opened or altered products. In limited cases, unused and unopened products may be eligible for return with prior authorization. Products damaged during shipment to the registered research location may be eligible for replacement. Please contact support for RMA review.
