Testing panels

What we test, and what each panel returns.

Eight panels covering peptides, the incretin class, small-molecule research chemicals, anabolic preparations and microbiological release testing. Every panel is quoted per submission. Email the details and we reply with price, turnaround and a submission reference.

Panel 01

GLP-1 & Incretin Analogues

Quantitative identity, purity and net content for the incretin class, including GLP-1, dual and triple agonists, and amylin analogues.

Included
  • Peptide purity by RP-HPLC-UV
  • Net peptide content per vial against reference standard
  • Identity confirmation by retention time
  • Molecular formula and CAS verification on the certificate

Reported as area % purity and absolute mg recovered per vial.

Turnaround

Panel 02

Research Peptides

The general peptide panel. Covers secretagogues, repair and mitochondrial peptides, melanocortins, bioregulators and blends.

Included
  • Peptide purity by RP-HPLC-UV
  • Net peptide content per vial
  • Identity confirmation by retention time
  • Per-component quantitation on multi-peptide blends

Blends are resolved and reported component by component.

Turnaround

Panel 03

Research Chemicals & Small Molecules

Identity and assay for non-peptide research materials: small-molecule actives, oral compounds and powders.

Included
  • Assay / purity by HPLC-UV
  • Identity confirmation by LC-MS
  • Content per unit or per mL
  • Adulterant screen on request

Method is selected per compound; quoted with the estimate.

Turnaround

Panel 04

Anabolics: Oils & Orals

Ester identification and quantitation for oil-based injectables, plus content uniformity for oral solid dosage forms.

Included
  • Ester identity and quantitation by HPLC
  • Concentration in mg/mL, oil-based preparations
  • Content per tablet or capsule
  • Screen for undeclared additional actives

Multi-ester blends are reported ester by ester.

Turnaround
4–6 business days
Sample needed
1 mL of oil, or 5 units

Panel 05

Sterility & Bacterial Endotoxin

Microbiological release testing for anything intended to be handled as a sterile preparation.

Included
  • Sterility by nucleic-acid amplification (PCR)
  • Growth-based confirmation
  • Endotoxin by kinetic chromogenic LAL
  • Result in EU/mL against a stated limit

Vials are opened only inside the laboratory's containment.

Turnaround

Panel 06

Elemental Impurities

Heavy-metal screen by ICP-MS, with limits aligned to the compendial expectations for parenteral routes.

Included
  • Arsenic, cadmium, lead, mercury, chromium
  • Limits aligned to USP <232> / <233>
  • Reported in ppm with the method limit shown
  • Extended element list on request

Digestion and analysis performed on the material as supplied.

Panel 07

Adulterant & Fentanyl Screen

Targeted presence analysis for fentanyl and common analogues, run as an incoming-material integrity check.

Included
  • Targeted LC-MS/MS screen
  • Fentanyl and common analogues
  • Reported as detected / not detected
  • Extended adulterant list on request

Included as standard in the full certificate panel.

Panel 08

Full Certificate Panel

Everything above, run as one submission and issued as a single certificate of analysis with a scannable verification code.

Included
  • All 11 analytes on one certificate
  • Purity, net content and identity
  • Full elemental, sterility and endotoxin work-up
  • QR-verified certificate hosted on this site

This is the panel behind every certificate in our verification index.

Turnaround

At a glance

Turnaround and sample requirement by panel.

Turnaround runs from the day the sample is logged in against its submission reference, not the day it was posted.

Send sealed units wherever possible. A vial we open ourselves, inside the laboratory, is the only kind we can report sterility and endotoxin against. Material arriving already opened can still be assayed for identity, purity and content, but the microbiological result would describe your handling rather than the lot.

How submission works

From quote to certificate.

1

Ask for a quote

Email us the compound, the labeled content, how many lots, and which panel you want. We reply with price, turnaround and a submission reference.

2

Ship the sample

Send sealed units, unopened, with the submission reference on the outside. We log them in against the reference on arrival.

3

Analysis

Samples run inside the stated turnaround. If anything falls outside specification we contact you before the certificate is issued.

4

Certificate issued

You receive a certificate of analysis carrying a certificate number, an access code and a QR code that resolves to a record hosted here.

Request testing

Every panel starts with an email.

Include the compound, the labeled content per vial, the number of lots and the panel you want. If you are not sure which panel fits, describe the material and we will tell you.
