Talk to a human.

Tell us which material it is and your order number, and add the lot number from the vial label if it has one. No certificate of analysis is published for any listed material right now, so what we can confirm is the specification on file — purity, analytical method, physical form and fill size. We will not send you a certificate we do not have, and we will not hand you a document for some other material instead.

Contact us within 7days of delivery with your order number and photos. You’re entitled to a replacement or a full refund, and this applies whether or not the seal is intact. Don’t ship anything back before we reply — we’ll tell you whether to return, keep, or safely dispose of it. See Returns.

Unopened items with an intact tamper-evident seal can be returned within 30days of delivery, with no restocking fee. Message us first so we can confirm eligibility and give you a return address — a package that arrives without that can’t be matched to your order. Full terms under Returns.

Ask. We’ll answer with specification, analytical method, and documentation. What we will not do is advise on use — no dosing, no administration, no protocol guidance, and no discussion of effects in humans or animals. That’s not evasiveness; these are research materials and that boundary is a condition of how they’re sold. See Research Use Only.

Email privacy@tydelab.com from the address on your account and tell us what you want: a copy of what we hold, a correction, deletion, or to stop marketing email. We honor these regardless of what state you live in. See Privacy Policy.

Tell us and we’ll fix it. Tyde Labs does not make health, therapeutic, or performance claims, and we treat a line that reads like one as a defect worth correcting — not a matter of opinion.
