Every batch, third-party verified.
We third-party test every product in an ISO/IEC 17025 accredited laboratory for endotoxins, heavy metals, purity and content — using the most advanced technology available in the United States.
Vanguard LaboratoryOlympia, Washington · USATested in America, by a lab that isn't us.
Most batches go to Vanguard Laboratory in Olympia, WA before they're allowed to ship — an independent, ISO/IEC 17025:2017 accredited lab, also accredited by the Washington Departments of Ecology and Health for the analysis of drugs and controlled substances. A few product lines — atomized sprays and some capsule blends — are tested by other independent labs (ILS, Bioviridians, Freedom Diagnostics); each product page links its own report.

The 10-point verification panel.
No vial ships until it clears all ten. Ten of ten, or it doesn't leave the building.
Purity
HPLC-UV/VISConfirms the vial contents are the actual analyte — no unexpected peaks, no shortfall.
Quantity
HPLC AssayVerifies the vial holds the amount printed on the label, within spec.
Identity
LC-MSConfirms the molecular identity matches the intended compound.
Endotoxins
LALScreens for bacterial-derived toxins left over from manufacture.
Heavy Metals
ICP-MSChecks for arsenic, cadmium, lead, and mercury carried into the product.
Sterility
USP <71>Batch is screened for viable microbial growth before release.
Fentanyl Screening
LC-MS/MSEvery batch is screened against fentanyl and its analogs for a clean result.
Solubility
TurbidimetricReconstitution is verified to dissolve clean and behave as expected.
Vial Seal Integrity
CCITThe seal is confirmed to hold from the fill line all the way to you.
Multi-Vial Conformity
Batch QCVials are cross-checked so the batch stays consistent, unit to unit.
Full ten-of-ten, pulled straight from the record.
Elite is the top coverage tier in the Vanguard system — all ten points are part of the batch's testing, not a partial subset. A point only lights up when the lab's own record backs it. Nothing is assumed.
- Independently analyzed Third-party ISO/IEC 17025 lab, not in-house.
- Tied to the batch Every result maps to the exact lot and vial.
- Permanently verifiable Each batch carries its own scannable record.

Explore the full FAQDo your peptides undergo quality testing?
Yes. Each peptide undergoes multi-panel laboratory testing to assess purity and content, along with endotoxin screening, heavy metal analysis, and sterility testing.
What is the typical purity of your peptides?
Our peptides typically test at over 99% purity. Each batch is verified using laboratory methods such as HPLC, with supporting documentation available in the COA library.
How are your peptides synthesized?
Peptides are produced using solid-phase peptide synthesis (SPPS), where amino acids are added step-by-step in a controlled sequence. After synthesis, the peptide is cleaved, purified (often via HPLC), and verified using analytical testing such as mass spectrometry to confirm identity and purity.
How do I check the report for my vial?
Every vial has its lot number printed on the label and its own QR code. Scan it, or search the lot on Vanguard's report hub, to open that lot's record on the lab's own website.
