PURPLE VERIFIED™EVERY BATCH8XTESTED

Eight assays. Every batch.

The same 8X testing panel runs on every Purple batch. Here is what each test proves.

Peptide Purity

01
RP-HPLC · 214 nm

Reverse-phase HPLC quantifies the target peptide against every related peak. Release requires 99%+ purity on every batch.

Net Peptide Content

02
HPLC quantitation

Confirms the actual peptide mass in the vial matches the amount stated on the label.

Identity

03
HPLC–RTM

Each batch is matched against a certified reference standard to confirm the compound is exactly what the label states.

Appearance

04
Visual inspection

The lyophilized cake is inspected for color, uniformity and physical integrity before a batch is released.

Fentanyl Screen

05
Immunoassay

Every batch is screened for fentanyl contamination before it clears release.

Heavy Metals

06
ICP-MS

Arsenic, cadmium, lead, mercury and chromium are quantified by mass spectrometry against strict screening limits.

Sterility

07
PCR

Microbial detection verifies that no bacterial or fungal growth is present in the vial.

Endotoxin

08
USP 85 · Kinetic

Bacterial endotoxin is quantified in EU/mL by the kinetic method and reported on each certificate.

Tested where it matters. Every batch.

Every current PP batch is backed by batch-specific laboratory documentation. View the actual results directly from the certificate.

Peptide Purity

01
HPLC

Measures the purity of the peptide in the tested batch. The exact reported purity result is shown alongside each current PP lot.

Endotoxin

02
Bacterial endotoxin test

Where endotoxin testing is available for the current batch, the corresponding laboratory report is published alongside the purity certificate.

Batch-Specific Results

03
Lot verified

Each certificate is connected to a specific PP lot number so the report can be matched directly to the batch being displayed.

Original Certificate

04
Direct COA access

Open the actual laboratory certificate and review the reported results directly.
