Pure Bio Labs Review: Public Lot-Coded COA Library, Unnamed Labs and Mixed Formats

Pure Bio Labs is the store of Pure Bio Labs LLC, which lists a mailing address in San Antonio, Texas, a phone line and an email address. It sells freeze-dried research peptides in sealed vials, but also self-administration formats such as liquid sprays, capsules and topical products, plus pre-mixed liquid "substrates" and multi-item research sets.

We looked at the homepage, the full collection, three product pages, the COA library, the testing standards page, the FAQ, the RUO policy and the contact page. The shipping and refund policy pages could not be read, so those terms come from the FAQ.

What Pure Bio Labs sells

The full collection showed 128 listings when we looked, sorted by format into vials, liquid sprays, substrates, capsules, topicals and research sets. Roughly a third are single vials, covering compounds such as BPC-157, TB-500, GHK-Cu, Epithalon, Ipamorelin, 5-Amino-1MQ, SNAP-8 and several GLP-1 class compounds. Single vials ran from about $45 to $200.

The non-vial formats are ready-to-use products rather than research materials in the usual sense, and they are the main reason this store scores lower than its paperwork alone would suggest.

A public COA library with lot codes but no named lab

The COA library lists about 100 reports and is open without an account. Each product links to its own report page, and the summaries we saw show net content against the label (for example, 10.16 mg in a 10 mg SNAP-8 vial), HPLC purity above 99% for most vials, an identity result marked "Confirmed", endotoxin levels, heavy metals and a microbial screen.

Lot codes such as SX-5136-PB appear on some product pages and in report file names, which helps with batch matching. There are gaps:

• No testing lab is named, although the testing page refers to ISO/IEC 17025 accreditation.
• No report dates or verification links are shown.
• One lot code appears on two different CJC-1295 listings.
• Mass spec is named as the identity method, but observed and expected masses are not summarized.

The testing standards page is candid about what each test can and cannot show, and notes that panels vary by product and batch.

Labeling and purchase checks

Research-use-only notices appear in the footer and on every product page, with an FDA disclaimer and a statement that products are not for human or animal use. Product pages give storage guidance but no usage directions, and support says it will not give human-use or clinical guidance. Some descriptions also mention the properties a compound is studied for, which goes beyond strict research-use labeling.

Selling sprays, capsules and topicals alongside vials does not fit research-use-only supply, whatever the notices say. No entry gate was seen. The FAQ says buyers complete a research-use acknowledgement at checkout and must meet the site's age requirement, but it does not state the age.

Ordering, shipping, refunds and support

Payment methods are shown only at checkout. According to the FAQ, weekday orders placed before 2 pm Central usually ship the same business day, later orders the next business day, and standard US delivery takes about two to four business days after dispatch. Tracking is emailed, and buyers are asked to photograph any parcel that arrives warm. No cold-pack use or shipping origin is stated.

Returns need written authorization from support before anything is sent back, and opened or used items are generally not eligible. Damaged, defective or wrong items should be reported promptly with the order number, lot details and photos. The FAQ gives no return window and points to separate policy pages for the full terms.

Support runs through email, phone and a contact form that asks for the product and batch number.

Verdict: who Pure Bio Labs suits and what to check

Pure Bio Labs suits labs that value broad, publicly posted batch summaries with net content, endotoxin and microbial results, and a reachable Texas business. It is a weaker fit for buyers who want a named lab, or a supplier that keeps to research vials.

Before ordering:

• Open the report for your exact product and strength, and note the lot code.
• Ask support which lab issued it and whether it includes a mass spec result.
• Read the shipping and refund policy pages for the return window before paying.
