Is Biolongevity Labs a legitimate peptide vendor?

Biolongevity Labs shows the signals researchers use to vet a vendor. It operates under publicly identified leadership, publishes lot-specific Certificates of Analysis from MDx BioAnalytical Laboratory, an independent US lab, with publicly searchable identifiers, and is a verified member of the American Peptide Association. Products are sold for laboratory research use only, so confirm the relevant COA before purchasing as you would with any vendor.

Do Biolongevity Labs peptides include third-party testing?

Yes. Lot-specific Certificates of Analysis are provided for products, verifying identity and purity through independent laboratory testing using HPLC and mass spectrometry. COAs are publicly searchable through MDx BioAnalytical Laboratory.

What is the current Biolongevity Labs coupon code?

The current verified Biolongevity Labs coupon code is PROBIO15 for 15% off eligible orders. The Project Biohacking team checks it monthly; last verified July 2026. Copy it from the box above to apply at checkout.

How long does Biolongevity Labs shipping take?

Most US orders ship the same business day when placed before 12 noon PST, then arrive within 2 to 5 business days via standard shipping. Expedited FedEx 2 Day and Next Day options are available at checkout. Orders over $400 qualify for free standard shipping.

Does Biolongevity Labs ship internationally?

Yes, international shipping is available. Customers are responsible for any applicable duties, taxes, or import restrictions based on their country.

What makes Biolongevity Labs different from other vendors?

Per-lot COAs rather than per-product documentation, and a catalog anchored by specialized compounds, particularly Klotho, that most vendors do not carry.

Are Biolongevity Labs peptides intended for human use?

No. All products are sold for research and laboratory use only and are not approved for human consumption.

Can beginners purchase from Biolongevity Labs?

The platform is accessible to new researchers. Understanding peptide handling, reconstitution, and storage before purchasing is strongly recommended.

Where can I learn more about Klotho or Follistatin?

Detailed educational guides are available on Project Biohacking. Start with the Klotho peptide guide for research context and mechanism breakdowns.

Does Biolongevity Labs sell bioregulators?

Yes. Biolongevity Labs carries a bioregulator catalog built around the Khavinson series, including Vilon, Epithalon, and Thymalin, alongside its peptide and proprietary blend lineup. These are short-chain peptides that are sensitive to synthesis quality, so the lot-specific Certificates of Analysis from MDx BioAnalytical Laboratory are worth reviewing before purchase. Most bioregulator products are eligible for the verified 15% discount.

Has Biolongevity Labs received an FDA warning letter?

As of July 2026, Project Biohacking is not aware of any publicly listed FDA warning letter issued to Biolongevity Labs. We monitor vendor regulatory status as part of our review process. If you have specific concerns, check the FDA's public warning letter database directly.

Biolongevity Labs Coupon Code & Review PROBIO15: 15% Off July 2026

Biolongevity Labs Coupon Code: Verified July 2026

Biolongevity Labs is a featured vendor in the Project Biohacking peptide vendor directory. The coupon code is verified monthly by the Project Biohacking team and applies on top of most active promotions. During seasonal sales, combined savings of up to 40% off retail have been reported.

Only one coupon code can be entered per order, so PROBIO15 is the code to use. It applies on top of most automatic storewide promotions. When a storewide sale is already running, checkout rules occasionally give the sale price precedence, so confirm the final discount before paying.

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
The code stacks with most active promotions for meaningful combined savings
Active loyalty rewards, referral bonuses, and subscriber-exclusive offers

Cons

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

Overall Verdict: 4.9 / 5 (Project Biohacking Editorial Score)

Biolongevity Labs earns its rating through verifiable quality documentation and access to compounds that most vendors do not stock. For researchers who prioritize testing transparency and need a reliable source for Klotho or advanced proprietary blends, the 15% code makes them a competitive choice in 2026. Researchers who need a broad catalog at lower price points may want to compare options in the vendor directory first.

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.

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.

For researchers comparing vendors across the full catalog, the Project Biohacking vendor directory covers quality standards, pricing tiers, and compound availability across sourcing options.

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.
