Biolongevity Labs Review 2026 – Premium Research Peptide Vendor

Logo of Biolongevity Labs, blue square with a DNA double helix in the corner, blue text on white background.

Biolongevity Labs is a US-based research peptide vendor focused on documentation transparency, third-party testing, and specialized compounds. All products are sold strictly for research and laboratory use only and are not intended for human consumption.


The research peptide vendor distinguishes itself in three specific ways: lot-specific Certificates of Analysis published for every product batch, a catalog built around hard-to-source compounds, most notably the Klotho peptide and a consistent manufacturing standard backed by independent HPLC and mass spectrometry verification.

Pros

  • Per-lot COAs from independent third-party labs, not just per-product documentation
  • Specialized catalog: Klotho, Cell Factors™, FLGR242 Follistatin, and proprietary blends

Cons

  • Premium pricing on specialized formulations relative to larger-catalog vendors
  • Focused catalog, better suited to targeted sourcing than broad compound shopping


Overall Verdict: 4.7 / 5, Standards Score 74 / 100 (Project Biohacking Editorial Score)


Biolongevity Labs stocks compounds most vendors do not carry, including Klotho as a standing SKU and proprietary blends such as Regeno and Cell Factors. Its certificates come from MDx BioAnalytical Laboratory and are tied to specific lots, as covered in the section below.

Third-Party Testing and Quality Documentation

Certificate of Analysis from MDx Biotech Laboratories with tables, chart, and spectrum for a sample analysis

Biolongevity Labs uses MDx BioAnalytical Laboratory, Inc., a veteran-owned US analytical lab, for independent compound verification. The COA referenced here is a real example from their Klotho inventory, not a placeholder or generic document.


What the documentation confirms for this batch:

Identity: Confirmed as a-Klotho MAB via mass spectrometry. The spectrum is lot-specific, tied to QC tracking number QC260075, not a generic product-level run.

Purity: 99.71%, determined by liquid chromatography. The chromatography trace is included on the certificate.

Endotoxin: Passed at the ≤0.05 EU/mL threshold, a meaningful data point for researchers working with sensitive assay conditions where endotoxin contamination would compromise results.

Appearance: White crystals, consistent with properly lyophilized peptide.


This certificate carries COA identifier 260086 and is signed by Jason Snitker, Operations Manager at MDx. It is publicly searchable on mdxbiolabs.com under the Certificates of Analysis tab using search code 260086. Identity, purity, and endotoxin are all reported on this single lot-specific certificate, giving each batch a complete documentation chain across all three analyses.

American Peptide Association Member

Biolongevity Labs is a verified member of the American Peptide Association, the industry body advancing compliance, education, and research-grade standards in the peptide market.

What Sets Biolongevity Labs Apart

Most research peptide vendors offer similar compound lists with similar documentation. Biolongevity Labs differentiates on three specific points that matter to researchers who care about what they are actually receiving.


Per-lot COAs, not per-product. Most vendors publish a single Certificate of Analysis per product and update it infrequently. Biolongevity Labs publishes lot-specific documentation, meaning the COA you review corresponds to the exact batch you are ordering, verified through independent HPLC and mass spectrometry testing.


Klotho availability. Verified Klotho peptide is genuinely difficult to source. Biolongevity Labs has built their catalog around it and maintains multiple configurations with the same documentation standards applied to every other compound they carry.


Proprietary formulations with full documentation. Cell Factors™, FLGR242, and the Regeno Blend are not generic off-the-shelf compounds. They are purpose-built formulations, each backed by the same independent testing infrastructure as their single-peptide offerings.


Who's Behind Biolongevity Labs: The Founding Team


In the research peptide market, founder transparency is rare. Most vendors operate with no public scientific or business leadership, no documented credentials, and no accountability beyond the website itself. Biolongevity Labs takes the opposite approach. The company was founded by three publicly identified leaders, each with extensive credentials in their respective domains, and each personally tied to the company's reputation. Biolongevity Labs is also a member of the American Peptide Association (APA), the industry body for compliance, education, and research-grade standards.

Featured Research Peptides and Bioregulators

Two clear glass vials with silver caps labeled

Biolongevity Labs stocks several advanced and difficult-to-source research compounds, including the Klotho peptide  (alphaKlothoLR), ShredX, PT-141 (Bremelanotide), Cell Factors™, Follistatin (FLGR242), Regeno Blend (BPC-157/TB-500/Cartalax), and a dedicated bioregulator catalog featuring Vilon, Epithalon, and Thymalin. 


All are produced with strict purity standards, third-party testing, and lot-specific Certificates of Analysis. 


Among the most notable is the Klotho peptide, one of the more specialized compounds available within the Biolongevity Labs lineup and a key differentiator in their catalog.

Klotho Peptide (alphaKlothoLR)

alphaKlothoLR is one of the more distinctive offerings in the Biolongevity Labs catalog, available in multiple configurations to support different research applications. Each lot is produced under strict purity standards and supported by third-party testing and detailed Certificates of Analysis.


Khavinson Bioregulator Catalog

The Khavinson series are short-chain peptides developed by Russian gerontologist Vladimir Khavinson and studied for tissue-specific cellular signaling is one of the most synthesis-sensitive classes of compounds in the research peptide market. Biolongevity Labs maintains one of the deepest bioregulator catalogs in the U.S. research market, with compounds available in both vial and capsule formats. The catalog includes Cartalax, Epithalon, Vilon, Cortagen, Bronchogen, Testagen, Pinealon, Cardiogen, Thymulin, Livagen, and Ovagen, with each batch produced under the same lot-specific Certificate of Analysis standards as their single-peptide offerings.


Cell Factors™

Cell Factors™ is Biolongevity Labs’ multi-component peptide complex, positioned as one of the more advanced formulations in their research catalog. It is produced to the same high standards, with third-party testing and lot-specific Certificates of Analysis.


Follistatin (FLGR242)

FLGR242 is Biolongevity Labs’ proprietary version of follistatin, offered in multiple vial configurations to support a range of research designs. As with all products in their catalog, it is manufactured under strict purity standards and supported by full third-party Certificates of Analysis.


Regeno Blend (BPC-157 / TB-500 / Cartalax) – 30 mg

Regeno Blend combines multiple well-known research peptides into a single 30 mg vial, simplifying sourcing for multi-compound research protocols. The formulation is produced under strict quality controls with third-party testing and lot-specific Certificates of Analysis.

Handling, Packaging and Returns

How the material is packaged

Biolongevity Labs ships lyophilized peptides at ambient temperature in protective packaging. A cold pack is sold as a $9.99 add-on for peptides shipped in hot weather. Offering temperature protection at all is not universal in this market, and requiring Next Day for it is the correct constraint rather than a marketing gesture. A cold pack in a five-day parcel is a warm pack by day two. Biolongevity ships worldwide and includes customs and import paperwork for selected countries. Duties, taxes, and local import rules are the buyer's responsibility.


Returns

Biolongevity Labs states its return terms on two pages, Refunds & Returns and Shipping and Payments, and each one says two things. Both open by ruling returns out, one citing quality control and the fragile nature of the products, the other citing regulations on their sale. Both then accept unopened products within 10 days of delivery, less a 15% restocking fee and the cost of the return shipping label.


If an order arrives with missing, incorrect or damaged items, Biolongevity directs customers to email help@biolongevitylabs.com, and the Shipping and Payments page says a wrong shipment is replaced. Cancellations must be requested by email before the order ships.


No returns on research compounds is standard across this category, and the replacement route for wrong or missing orders is the part that matters. Because the written terms conflict, confirm eligibility with Biolongevity support before relying on a return.


Ordering From Biolongevity Labs


Biolongevity sells through two stores, Labs and Supplements. The Biolongevity Labs coupon code page has the Project Biohacking code that works on both.
