Question 1

Are these products for human use?

Accepted Answer

No. All products are sold strictly for in vitro and laboratory research. They are not for human or veterinary use, not for diagnostic procedures, and have not been evaluated by the FDA.

Question 2

Where is Refined Biolabs based?

Accepted Answer

We are a US-based company. Sourcing, QC, fulfillment, and support are all handled domestically.

Question 3

Who tests your peptides?

Accepted Answer

Every batch is independently tested by an ISO 17025-accredited third-party laboratory. The certificate of analysis is published on the product page and linked to the batch ID on the vial.

Question 4

What is your purity standard?

Accepted Answer

We hold a 99%+ purity floor. If a batch doesn't meet that mark, it doesn't ship — there is no second-tier inventory.

Question 5

How are orders shipped?

Accepted Answer

Orders ship in plain, sealed, unmarked packaging. Cold-sensitive compounds ship with insulated packaging and gel packs sized for the destination zone.

Question 6

Do you ship internationally?

Accepted Answer

We ship across the US and to select international destinations where research peptides are legally importable for laboratory use. Check the shipping page for the current country list.

Question 7

How long until my order arrives?

Accepted Answer

Standard US orders ship within 1 business day and arrive in 2–5 business days. Express options are available at checkout and free for Reserve members.

Question 8

How should peptides be stored?

Accepted Answer

Store lyophilized peptides in a cool, dry, dark place. Once reconstituted in your laboratory, store as your protocol dictates. We do not provide reconstitution or dosing guidance.

Question 9

Can I return an order?

Accepted Answer

If a vial arrives damaged or fails to match its COA, contact us within 7 days and we will replace or refund it. Opened or used product is non-returnable.
