Every batch of every Noki Labs peptide is independently tested. We publish the Certificate of Analysis (CoA) for each batch publicly so you can verify identity, purity, and bioburden before — or after — you order. No log-ins, no email gates, no "contact for CoA" runaround.
Why this page exists
The peptide market in the Philippines is full of suppliers who claim third-party testing but cannot show you the lab report. We think that's the line between a trustworthy product and a guessing game. Our answer: publish every CoA, link it to a batch number, and let you cross-check it before you reconstitute a single vial.
If you're new to peptides, a Certificate of Analysis is the lab report that confirms three things: (1) the molecule in the vial is actually the molecule on the label, (2) the purity meets the stated minimum (we hold to ≥99%), and (3) bacterial endotoxin and microbial counts fall within safe injectable ranges.
How to find your batch's CoA
-
Find your batch number. It's printed on the vial label and on the certificate that ships with every order. Format:
NL-[peptide]-[YYMM]-[lot](example:NL-TIRZ-2604-A12). - Match it to the table below. Each row links to the full PDF CoA for that batch.
- Read the report. The first page of every CoA shows molecular identity (HPLC + MS), purity percentage, and bacterial endotoxin level.
What every Noki Labs CoA includes
- Identity verification via HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry — confirms the molecule matches the labeled peptide sequence.
- Purity quantification — expressed as a percentage; Noki Labs minimum is 99%.
- Bacterial endotoxin testing (LAL test) — confirms safe injectable thresholds.
- Microbial count — total aerobic plate count and yeast/mold counts.
- Manufacturer name + manufacture date.
- Independent third-party laboratory signature and date — we do not test our own product.

Our testing partners
Noki Labs uses accredited third-party laboratories for every batch. Identity (HPLC, MS) and purity assays are run by ISO/IEC 17025-aligned labs. Bacterial endotoxin testing is performed by a separate analytical lab to maintain independence between identity and microbial verification.
How we manufacture
Noki Labs sources peptide compounds exclusively from GMP-compliant manufacturers with verified quality systems. Every shipment from manufacturer to our Manila warehouse is logged with a temperature data logger — cold-chain integrity is documented from production line to packing bench.
We don't dilute, repackage, or relabel. The vial that lands at your door carries the manufacturer's original batch identifier on the label, traceable back through our records to the specific HPLC trace that earned the CoA.
Verifying authenticity — Lemon Bottle, Aqualyx, branded imports
For products we import as authentic brand-name compounds (Lemon Bottle from Korea, Aqualyx from Italy), we verify the original manufacturer's serial code and ship the unit with its original batch documentation. We do not co-mingle imports with our own peptide line.
What if a batch fails QC?
It happens — rarely, but it does. When a batch falls below our purity minimum or shows out-of-spec endotoxin levels, we destroy the lot and reorder. We never blend a failed lot into a passing one to bring the average up. If you ever receive a vial whose CoA you cannot verify on this page or via support, contact us within 7 days and we will refund or replace the order.
Why publish CoAs at all?
Three reasons:
- Trust requires evidence. Saying "lab-tested" is meaningless without showing the lab report.
- Buyers deserve traceability. When you inject something, you should know exactly what's in the vial — not approximately.
- The market needs better defaults. If more suppliers had to publish, fewer suppliers could quietly cut corners. We're voting with our practices.
Questions about a specific CoA?
Email support@nokilabs.com with your batch number. We respond within 1 business day. If you'd rather see CoAs in person, the original signed lab reports live in a binder at our Manila warehouse — you can review them by appointment.
