Frequently Asked Questions

Answers about ordering, shipping, purity testing, and compliance. Can’t find what you need? Contact us.

Ordering & Payment How do I place an order?

Browse the shop, add products to your cart, and check out — no account required, though creating one lets you track past orders and reorder faster.

Ordering & Payment What payment methods do you accept?

We accept major credit and debit cards, along with a few additional options at checkout. All transactions are processed over a secure, encrypted connection.

Ordering & Payment Can I cancel or change an order after placing it?

If your order hasn’t shipped yet, contact us right away and we’ll do our best to adjust or cancel it. Once it’s handed off to the carrier, we’re no longer able to make changes.

Shipping How fast is shipping?

Orders are picked, packed, and handed to the carrier the same or next business day. Domestic delivery is typically 2 days from dispatch; international timelines vary by destination.

Shipping Do you ship internationally?

Yes — we ship to most countries with cold-chain packaging and tracked delivery. Customs handling and delivery windows vary by destination, and the buyer is responsible for compliance with local import regulations.

Shipping How are products packaged?

Every order ships cold-chain in discreet, unmarked packaging with insulation and ice packs sized for transit time, so contents stay stable from our facility to your door.

Shipping Can I track my package?

Yes. A tracking number is emailed as soon as your order ships, and it’s also visible under Order Tracking in your account.

Purity & Lab Results What does “research use only” mean?

Our products are sold strictly for in-vitro laboratory and research purposes. They are not intended for human or veterinary use, consumption, diagnostic, or therapeutic application. By purchasing, you confirm the products will be used only for legitimate research.

Purity & Lab Results Where can I find the Certificate of Analysis for my batch?

Every product page links to its current CoA, and the batch number on your shipping label corresponds to the report on our Lab Results page. Message us if you can’t locate one and we’ll send it directly.

Purity & Lab Results What purity standard do your products meet?

Our products are independently verified at ≥98% purity via HPLC. Exact results for each batch are documented on its Certificate of Analysis, not just the general spec.

Purity & Lab Results Who performs your third-party testing?

Testing is conducted by independent laboratories with no financial stake in our sales, using HPLC-UV analysis referenced against certified standards. Lab details are listed on each CoA.

Account & Orders Do I need an account to place an order?

No — guest checkout is available. Creating an account just makes it easier to track orders and reorder in the future.

Account & Orders What’s your return policy?

Because these are lab materials shipped cold-chain, we’re not able to accept returns once an order has shipped. If something arrives damaged or incorrect, contact us within 48 hours and we’ll make it right.

Compliance Are these products approved for human or animal use?

No. All products are sold exclusively for laboratory and research purposes and are not approved, labeled, or intended for human or animal use, consumption, or as a food, drug, cosmetic, or medical device.

Compliance Do I need to provide proof of research affiliation to order?

We don’t require documentation at checkout, but by completing a purchase you agree that the products will be used solely for legitimate research purposes, per our Terms of Service.
