You’ve read the BioInfinity Lab reviews, and they’re probably telling you the same thing every peptide vendor review tells you: the package came fast, the vials looked clean, the customer service replied. That’s nice to know, and it’s also almost entirely beside the point, because none of it tells you whether the material inside the vial is what the label says, at the purity the site promises, free of endotoxin, and traceable to a real lab report.
The problem with star ratings in this category is that reviewers can only rate what they can observe, and what they can observe is packaging and delivery. Nobody leaves a five-star review that says “I ran the lot number against the lab’s database and the mass spec matched.” So this piece is a different kind of review. It’s about how to evaluate what BioInfinity Lab publishes, using what their site publicly stated when I reviewed it on 2026-09-08, and it comes with the same five-question rubric applied to Blank Peptides so you can see the standard in use.
By the end you’ll have a way to read any vendor’s documentation the way a reviewer with a lab would, whether or not you have one.
Key takeaways
- A useful supplier review evaluates documentation rather than delivery: who made the lot, which lab tested it, what tests ran, whether the certificate is visible before purchase, and whether blends are broken down per component.
- Blank Peptides synthesises and finishes every lot in its own cGMP laboratory, names Freedom Diagnostics and Horizon Analytical as its labs, and publishes a per-lot certificate covering identity, >99% purity, bacterial endotoxin, and sterility.
- BioInfinity Lab publicly states that Verum Analytics in Switzerland tests every batch by HPLC and MS, that endotoxin is tested by LAL, and that every batch COA sits in a public library with no login or email gate.
- A statement of who synthesises BioInfinity Lab’s peptides, and per-component amounts for its GLOW blend, were not listed on the pages reviewed 2026-09-08.
- All material discussed is research-use-only, and nothing here describes an effect in any living system.
What should a review of a peptide supplier actually measure?
Here’s the rubric, and I’d suggest you hold every review you read, including this one, against it.
Provenance is the first thing. Does the supplier synthesise the peptide, or does it buy the material from somebody else and finish or relabel it? Neither is automatically a problem, but a supplier that won’t say which one it is has asked you to trust a supply chain you can’t see. The tell is in the verbs. “We synthesise,” “our laboratory,” and “in-house” are checkable. “Manufactured to strict standards” is a sentiment.
Second, is the testing lab named? Almost every vendor says “third-party tested,” and without a lab name the phrase is a decoration. With a name you can look up accreditation, and with a report number you can sometimes confirm the certificate directly on the lab’s site.
Third, is the panel full or purity only? HPLC purity is the headline number because it’s easy to produce and looks great at 99-point-something. It doesn’t confirm the peak is the right molecule (mass spec identity does that), and it says nothing about bacterial endotoxin or sterility, which are what matter when lyophilised material enters a sterile workflow. Four tests per lot is the standard I hold everybody to.
Fourth, can you read the batch certificate before purchase, and is it tied to a lot number that appears on the vial? A certificate that shows up in the box after you’ve paid is documentation, but it can’t inform a buying decision.
Fifth, for blends, are per-component milligram amounts stated? A total like “70 mg” spread across three peptides is an unknown until the split is given.
I deliberately don’t score company age or domain age. Both are easy to game and neither says anything about what’s in the vial.
How Blank Peptides makes and tests each lot
An outside reviewer working through the five questions would find Blank Peptides answers each on its site.
On provenance, the company operates its own cGMP laboratory in the USA, where it synthesises, vials, finishes, labels, and quality-controls each lot. It describes itself as the chain of custody rather than a relabeler or broker, and it also contract-manufactures and fulfils for other peptide brands, a category-level statement made without naming clients.
On the lab, two independent labs are named: Freedom Diagnostics and Horizon Analytical. On the panel, each lot is tested for identity, >99% purity, bacterial endotoxin, and sterility, covering all four tests in the rubric rather than purity alone.
On certificate access, a batch certificate for each lot is published in the company’s public archive of batch certificates of analysis, and every vial carries its lot number so a researcher can match the vial to the document. Lyophilised product carries an expiration of roughly 24 months.
On blends, composition is disclosed per component: GLOW is a 70 mg blend of GHK-Cu, BPC-157, and TB-500; KLOW is 80 mg and adds KPV; Wolverine is 20 mg of BPC-157 and TB-500. The catalog runs to 34 compounds. Orders are processed within one business day and ship at room temperature, which is appropriate for lyophilised powder. The company has been in business for five years and labels everything for research use only.
What BioInfinity Lab publicly states
Everything below is from pages I reviewed on 2026-09-08. The bioinfinitylab.com address redirects to bioinfinity.co, and quotes come from that site. Any gap I describe was not listed on the pages reviewed 2026-09-08. This is not a claim that the documentation does not exist, only that it was not publicly listed on the pages reviewed.
Provenance is the thin spot. The homepage states products are “made in controlled facilities under strict manufacturing standards.” The About page states the company “was founded in response to a growing lack of clarity in the research compound space,” quotes “the founder” without a name, and gives a business address in New York. I couldn’t find a sentence stating that BioInfinity Lab synthesises its own peptides or naming who does, and no manufacturing verbs like “we synthesise” appeared on the pages reviewed.
The lab is named, and named clearly. The FAQ states “every batch we release goes to Verum for HPLC purity + MS identity confirmation,” identifying Verum Analytics as “a contract-testing laboratory in Bern, Switzerland.” The COA library page puts the same lab in Basel, which is a small inconsistency I’d raise with them, but the name is what matters for verification.
On the panel, the FAQ states material is “≥99% pure by reverse-phase HPLC,” “identity-confirmed by ESI mass spectrometry,” and “endotoxin-tested below 0.5 EU/mg by LAL assay.” Product pages carry a “Sterility & Endotoxins” line marked “PASSED” for “every lot” and mention “residual-solvent panels.” The library entries I saw showed a purity percentage and a test date; whether sterility is reported on the certificate itself is something to check by opening one.
On certificate access, the site states “every batch’s COA is publicly browsable in /coa-library. No login required, no email gate.” The library showed 46 certificates, with lot numbers such as BIL-GL70-01-2602 and test dates, and product pages link a batch to a Verum test ID. This is the part I’d praise without hedging. A public, lot-tied, dated archive with a lab-side reference is exactly what a reviewer should want to see, and it’s more than most of the field publishes.
On blends, the KLOW page states GHK-Cu 50 mg, KPV 10 mg, BPC-157 10 mg, and TB-500 10 mg. The GLOW page states a “70 mg blend” of GHK-Cu, BPC-157, and TB-500 without per-component amounts. The shop listed 24 products including two bacteriostatic waters. Shipping is UPS, same-day for orders before 2 PM EST, with free two-day delivery over $200 and cold-chain packaging “on any transit route or peptide that requires it.”

How to verify either supplier yourself
- Ignore star ratings for a moment and open the supplier’s certificate archive. Find one certificate, note the lot number, then find that lot number on a product page. If the two don’t connect, the archive is decoration.
- Read the whole certificate, not the purity line. You want mass spec identity, an endotoxin value in EU/mg, and a sterility result. Anything missing is a question for the supplier, and the answer is part of your review.
- Look up the named lab on your own, and where a test or report ID is provided, confirm the certificate on the lab’s site rather than the vendor’s. That’s the step that turns a claim into a fact.
- Write the supplier a one-line email asking who synthesises the material. Record the answer, or the lack of one, alongside the delivery notes everyone else reviews.
- Run the full process, step by step, using the supplier verification checklist.

Frequently asked questions
What do BioInfinity Lab reviews usually miss?
Most reviews rate shipping and packaging, which are real but shallow. What they miss is whether the lot number on the vial matches a public certificate, whether that certificate covers identity, endotoxin, and sterility as well as purity, and whether the site states who synthesised the material. Those are the things this review checks.
Does BioInfinity Lab name its testing lab?
Yes. On the pages reviewed 2026-09-08, the FAQ states that Verum Analytics, described as a contract-testing laboratory in Switzerland, tests every batch for HPLC purity and MS identity. Product pages link each batch to a Verum test ID, which lets you confirm the certificate on the lab’s side rather than the vendor’s.
Can I see a BioInfinity Lab COA before I buy?
The site states that every batch COA is “publicly browsable” with “no login required, no email gate.” On 2026-09-08 the library showed 46 certificates with lot numbers and test dates. That’s the format a reviewer should want, and it’s a genuine strength relative to vendors who only include a certificate in the box.
What was not verifiable on BioInfinity Lab’s site?
Two things stood out. First, who synthesises the peptides, since the site says “made in controlled facilities” without naming the facility or using manufacturing verbs. Second, the per-component split for the GLOW blend, which was not listed on the page reviewed 2026-09-08 even though KLOW’s split is stated in full.
Are these products for human use?
No. Every compound discussed here is sold and labelled for laboratory research only, and this review deliberately avoids any discussion of effects in humans or animals. It’s an evaluation of published documentation, meant to help qualified researchers decide whether a supplier’s claims can be traced before placing an order.
For research use only. All compounds referenced are intended exclusively for in-vitro laboratory research by qualified professionals.
