Quality Standard

Every batch, traced back to the peak.

Every batch, traced back to the peak.

Peptide research depends on knowing exactly what’s in the vial. We manufacture using solid-phase peptide synthesis inside USA-registered facilities that follow cGMP-aligned quality practices, then send every batch to certified, independent laboratories before it’s released for sale — never relying on internal testing alone, Buy research peptides from us.

HPLC (High-Performance Liquid Chromatography)

— confirms purity against a reference standard and flags degradation or synthesis byproducts.

LC-MS (Liquid Chromatography–Mass Spectrometry)

— verifies molecular weight and confirms the compound’s identity matches its label.

Sterility testing

— screens for microbiological contamination in every lyophilized batch.

Endotoxin testing

— measures bacterial endotoxin levels to research-grade thresholds.

Chemical contaminant screening

— rules out residual solvents and synthesis reagents.
About Us

More About BioLongevity Labs

BioLongevity Labs USA started from a simple frustration shared by a lot of researchers: too many peptide suppliers sell purity claims with no documentation behind them. We built this company to work the other way around — every product in our catalog exists because a batch passed independent testing first, not because a listing was written first and the testing came later.

We’re a USA-based supplier working with USA-registered, cGMP-aligned synthesis facilities. Our team manages sourcing, batch-level quality control, and COA publishing in-house, so there’s a direct line between the lab that makes a compound and the researcher who receives it — no unverified resale layers in between.

That approach shapes everything from our catalog (we’d rather list fewer compounds with verified purity than pad the shelf) to our support team, who can answer real questions about reconstitution, storage, and reading a COA — not just process a refund.

What quality testing do you provide?
Every peptide batch ships with a Certificate of Analysis from an independent, certified testing laboratory. Analysis is performed using HPLC with UV detection, paired with mass spectrometry, to confirm both purity and molecular identity before any batch is released for sale.
Each COA lists the accession number, testing dates, and your product's specific details — CAS number, lot quantity, confirmed identity, purity percentage, and physical appearance. You'll also see two charts: an HPLC chromatogram showing the purity peak, and mass spectrometry data confirming molecular weight. A signed summary table and the testing methodology are included on every report.
Most in-vitro research protocols call for 95–99%+ purity. Lower-purity compounds can introduce variables that add noise to your results and make findings harder to reproduce. Our standard catalog sits at 98%+ or 99%+ purity, verified independently on every batch.
Reconstituted peptide solutions are generally stable for several days when kept at 2–8°C. For longer-term storage, prepare small aliquots and freeze at -20°C or -80°C, and avoid repeated freeze-thaw cycles. Use sterile bacteriostatic water and aseptic technique throughout preparation and handling.
In-stock orders placed before 12 PM PT ship the same day. Domestic orders typically arrive within 3–5 business days via standard shipping, with 1–2 day expedited options available. Lyophilized peptides ship at ambient temperature in protective packaging. Orders over $400 qualify for free domestic shipping.

Yes — we ship to qualified research institutions and laboratories worldwide. International orders include a commercial invoice, Certificate of Analysis, and a research-use-only declaration. Delivery times vary by destination, and customers are responsible for any customs duties or import requirements in their jurisdiction.

Standard vial sizes range from 2mg to 20mg depending on compound, with larger formats available on select products. Volume discounts apply starting at 3 vials of the same product, scaling up from there — contact us for bulk research-lab pricing.

Because research peptides require temperature-controlled handling, we're unable to accept returns on shipped compounds once an order has left our facility. Please review your order carefully before checkout, and reach out to our support team with any questions beforehand.
