Question 1

What does “for research use only” mean?

Accepted Answer

Every zylo product is sold as a laboratory reference material for in-vitro research. Nothing we sell is for human or veterinary use, and we don't provide dosing or administration guidance.

Question 2

How is each batch tested?

Accepted Answer

Every lot is tested by an independent laboratory: HPLC for purity and mass spectrometry for identity. Lots under 99% identity purity are never released. The certificate of analysis for every lot is published on our COA page.

Question 3

How do I find the COA for my vial?

Accepted Answer

Every vial ships with its lot number on the packing slip. Enter it on the COA page, or tap “View COA” on any product.

Question 4

How should vials be stored?

Accepted Answer

Keep lyophilized material sealed at −20 °C and protected from light. Once reconstituted, store at 2–8 °C. Capsules and lab supplies are kept at room temperature in a dry place.

Question 5

How does volume pricing work?

Accepted Answer

Discounts apply automatically to research compounds by the total number of units in your cart: 10% at 5+, 20% at 10+, 35% at 25+ (Research Access), 50% at 50+ (Research Access). Lab supplies are excluded.

Question 6

What is a Research Panel?

Accepted Answer

Pick any 4 vials and save 40% every month. Your panel ships monthly; change, pause or cancel any time from your account before the next renewal.

Question 7

Can I combine discounts?

Accepted Answer

Volume pricing, Subscribe & save (15%) and panel pricing apply per line. On top of that, the single best of your coupon, shared-bundle or referral discount is applied — and points can cover up to half the order.

Question 8

How do points and Business Credit work?

Accepted Answer

You earn 5 points per $1 on every order once it ships. 100 points = $1 at checkout. Business Credit packs add up to 25% bonus credit and spend exactly like points.

Question 9

How fast do orders ship?

Orders paid before 2pm PT on a business day usually ship the same day. Domestic delivery is 2–5 business days; express is 1–2. Every parcel is plain and unbranded.
