Quality & Testing (COAs) | Everything you need to know about ordering, payments, and shipping

Are your peptides third-party tested?

Products that display a COA icon on our website have been independently tested by Janoshik Analytical, a respected third-party laboratory. The testing is arranged by our fulfillment partners, and results are published on our website. Products without a COA icon are tested by the manufacturer in their own labs. If a product doesn't have a COA, we highly recommend testing it yourself -- you can submit samples directly at janoshik.com/c/peptides.

Do all products have COAs?

No. Only products with a COA icon on our website have third-party COAs from Janoshik Analytical. Products without this icon are tested internally by the manufacturer. If you purchase a product without a COA, we recommend independent testing before use. You can also form a group on our Telegram to split testing costs and send a sample to Janoshik Labs.

Why doesn't the COA cap color match my vial?

Cap colors can vary between production batches. If the batch code on your vial matches your shipping email, the product is correct even if the cap color differs from the COA photo. In some cases, a COA from a different batch may have been attached to your shipping email -- contact us and we'll send the correct one.

What is Noble Dragons' purity guarantee?

All products are backed by our Purity Guarantee: if Janoshik testing confirms any peptide to be below 97% purity, we will provide a full product refund and reimburse reasonable third-party testing costs. This applies to all products, whether or not they have a published COA.
