Arizen BioLabs Review: Posted COA Images, Unnamed Lab and Mixed Claim Windows

Arizen BioLabs, which also calls itself Arizen Labs, is a US online seller of freeze-dried research peptides. It describes itself as a chemical supplier rather than a compounding pharmacy, and it ships within the United States only.

We looked at the homepage, the shop, the BPC-157 product page, the COA page, the shipping and refund policies, the terms, the FAQ and the About page. The site carries clean research-use labeling and posts certificate images, but it leaves out the details that let a buyer check them: the lab's name, lot numbers and a business address.

Who Arizen BioLabs is and what the catalog covers

The About page describes a supplier of research-use-only compounds that ships from the USA, but it names no owners, staff, founding year, city or legal entity. The only published contact routes are a support email, a contact form and a Discord community.

The first of three shop pages lists 34 products. They include single peptides such as BPC-157, TB-500, KPV, Selank, Semax and SS-31, several blends, NAD+ and glutathione, a few house-coded listings such as ABL-3 RT, and two research water products. Prices for peptides run from about $40 to $180, with research water from about $10. Most listings show a starting price and hide size options until a product is opened. A few items, including IGF-1 LR3, were marked sold out when we looked. The menu also links a Sprays view, but no spray products appeared in it.

Testing claims and the COA image page

The homepage describes testing by independent, accredited US laboratories and lists an eight-point panel: purity, content, identity, heavy metals, sterility, endotoxin, a fentanyl screen and batch conformity. Elsewhere the same page refers to five quality checks, so the scope is not stated consistently. The product page for BPC-157 states purity of at least 99% by HPLC and mass spec.

The COA page lists 11 entries, each linking to an image file. Products covered include BPC-157 10 mg, GHK-Cu, KPV, NAD+, MOTS-C and several blends and house-coded listings. In the page text itself:

• No testing lab is named.
• No lot numbers or test dates are shown.
• No purity figures or mass values are listed for individual products.
• No verification code or lookup route is given.

The images may carry those details, but the site does not repeat them anywhere a buyer can match to a vial before ordering. The FAQ also says that certificates are posted only where available and that not every product has one, and the BPC-157 product page shows no lot number.

Before ordering, ask support for the certificate that matches your lot, check that it names the lab and shows mass spec results, and confirm it with that lab.

Research-use labeling and purchase checks

Labeling is one of the stronger areas. Product pages say the items are for qualified laboratory researchers only and not for human or veterinary use, food, cosmetics or household use. The footer repeats these points with an FDA notice, and the product page we checked gave storage notes only, with no usage instructions or health claims.

Age checks are thin. The terms set a 21+ minimum and say that placing an order confirms the buyer is a qualified researcher who will not give the products to people or animals. No entry gate or checkout checkbox was seen.

Ordering, payment and shipping

The FAQ and terms list cards and Zelle as payment methods. Cards carry a processing fee, and full payment is required before an order ships.

The shipping policy says orders ship in 1 to 2 business days, with weekend and holiday orders handled the next business day. Standard delivery takes about 3 to 5 business days, and express delivery costs $24.99 for 1 to 2 business days. Standard shipping is free on US orders over $200, but the cost below that is not listed. Tracking is emailed when the parcel ships.

Carriers and cold packs are not mentioned, and a footer badge promising same-day shipping does not match the 1 to 2 day policy. Shipping is limited to the United States.

Refunds, replacements and support

The refund page offers a free replacement for items that arrive damaged, defective or not as described, if support is told within 30 days of delivery. Parcels lost or damaged in transit are reshipped at no cost if reported within 30 days of the expected delivery date. Non-defective items cannot be returned once shipped.

The other documents are stricter. The terms say all sales are final except damaged or wrong items reported within 48 hours of delivery with photos, and the shipping policy asks for lost-parcel reports within 48 hours of the expected delivery date. Buyers should work to the shorter window.

Support runs through email, the contact form and Discord. No phone number, hours or reply time are stated.

Verdict: who Arizen BioLabs suits and what to check first

Arizen BioLabs suits US labs that want a broad catalog, clean research-use labeling and quick dispatch, and that are prepared to request and verify paperwork themselves. It is a weaker fit for labs that need a named lab, lot-matched reports and a published business address before ordering.

Before ordering:

• Ask for the certificate for your lot and confirm the lab name, lot number and mass spec results.
• Check whether your product is one of the 11 with a posted certificate.
• Report any delivery problem within 48 hours, the shortest window in the documents.
