Next Bio Peptides Review: Unnamed-Lab COAs, Thin Paperwork and 30-Day Returns

Next Bio Peptides, which also writes its name as NextBioPeptides, is an online store selling lyophilized research peptides to what it calls scientists and institutions. Its contact page lists a street address in Ketchikan, Alaska, a US phone number and an email address. No founding date or registered business entity is given.

We looked at the homepage, a product page, the COA page, the knowledge hub and the policy and contact pages. The store has a clear research-use framing and a detailed refund policy, but its testing paperwork is thin and in places does not line up with the products it describes.

What Next Bio Peptides sells

The catalog is small. The homepage shows NAD+ in 250 mg and 500 mg sizes, BPC-157 listings at 10 mg and 20 mg, and a 30 mg vial sold under the code TX-01 with no price shown. The COA page adds batch entries for a GLP-class compound listed as RC-X3, Tesamorelin, GHK-Cu, Ipamorelin and bacteriostatic water. Prices seen run from about $125 to $320.

Listings are not always tidy. One BPC-157 page has a 10 mg title, a quantity selector labeled 20 mg and a web address that mentions a second compound. The product page gives no physical format or purity figure of its own.

Testing claims and the COA page

The site says every batch goes through independent, accredited third-party testing, with HPLC for purity and mass spectrometry for identity, and that a signed COA comes with every lot. It does not name the lab.

The COA Testing page lists nine products, each with a batch code in the form NBP-2026-001 and a date of April 2026. The same three codes repeat across different products, and the page does not say whether the date is a test date. Only three entries link to a file:

• BPC-157 5 mg links to a PDF.
• Tesamorelin 5 mg links to a file named for a combined Ipamorelin and Tesamorelin report.
• GHK-Cu 50 mg links to a file named for a different compound entirely.

The other six entries say a COA is available but link nowhere. No measured purity or mass result appears on the page itself, so the 99%+ purity claim cannot be checked against named reports.

Labeling and the age gate

Research-use language is consistent. The entry gate, product pages and COA page all state that the materials are for in vitro laboratory work and not for human or animal use, and the product page reviewed carries no usage claims. The knowledge hub has four short articles on synthesis, research-grade materials and lab studies; one promotional post refers to the store under a different name.

Some shop category labels and one product nickname use effect-oriented wording, which falls short of strict research-use labeling. Visitors must confirm they are over 18 before entering. A separate 21+ or researcher confirmation was not seen on the pages reviewed.

Shipping, returns and support

The shipping policy is general. It says orders move once payment is confirmed, that methods and charges appear at checkout, and that some international destinations are served, with customs and duties left to the buyer. It names no carrier, processing time or ship-from location. The homepage says orders ship cold and dry with tracking, but the policy itself does not mention cold packs.

The refund policy is more specific:

• Unopened, sealed items can be returned within 30 days of delivery for a refund or exchange, after support issues an RMA number.
• Damaged, defective or wrong items, or items whose COA does not match the stated purity, must be reported within 48 hours with photos.
• Return shipping is the buyer's cost unless the store made the error.
• Refunds go to the original payment method within 5 to 10 business days of approval.

Support runs through a contact form and email. The contact page gives a US phone number, while the refund page lists only a UK WhatsApp number, and a homepage support button leads nowhere. Payment methods are not listed on the pages reviewed.

Verdict: what to check before ordering

Next Bio Peptides suits only buyers willing to check the paperwork themselves. Its research-use framing and refund terms are reasonable, but the testing record is the weakest part of the site: no lab is named, most COA links are empty and two posted files are labeled for other compounds.

Before ordering:

• Ask support for the full report for the exact batch you will receive, with the lab's name.
• Confirm that report directly with the issuing lab.
• Ask which carrier and ship-from location will be used, since the policy does not say.
