FAQQuestions researchers askResearch-use policy, product formats and shipping questions.
Questions researchers ask.
What does "research use only" mean?
Products are supplied for in-vitro laboratory research and analytical work. They are not for human or veterinary use, and we don't provide dosing or protocol guidance.
Why two numbers on every tile?
Sequence length and molecular mass are facts of structure. Both appear on the certificate of analysis, so anyone can check that the tile and the vial agree.
How do I read a certificate?
Purity (HPLC) tells you how much of the vial is the target peptide; identity (LC-MS) confirms which peptide it is; net content confirms the milligrams. Verified PDFs are linked from product pages when supplied; otherwise the certificate state is unavailable.
Which formats do you supply?
Vials only, at the moment: lyophilized powder in a sealed vial, with the lot and certificate on the label QR.
Where do you ship?
We ship worldwide. The US store covers the Americas in USD; the Europe store covers Europe and the rest of the world in EUR. See Shipping & payment for the current rates.
