Tests, every batch
Eight assays. Every batch.
The same 8X testing panel runs on every Purple batch. Here is what each test proves.
Peptide Purity
01Reverse-phase HPLC quantifies the target peptide against every related peak. Release requires 99%+ purity on every batch.
Net Peptide Content
02Confirms the actual peptide mass in the vial matches the amount stated on the label.
Identity
03Each batch is matched against a certified reference standard to confirm the compound is exactly what the label states.
Appearance
04The lyophilized cake is inspected for color, uniformity and physical integrity before a batch is released.
Fentanyl Screen
05Every batch is screened for fentanyl contamination before it clears release.
Heavy Metals
06Arsenic, cadmium, lead, mercury and chromium are quantified by mass spectrometry against strict screening limits.
Sterility
07Microbial detection verifies that no bacterial or fungal growth is present in the vial.
Endotoxin
08Bacterial 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
01Measures the purity of the peptide in the tested batch. The exact reported purity result is shown alongside each current PP lot.
Endotoxin
02Where endotoxin testing is available for the current batch, the corresponding laboratory report is published alongside the purity certificate.
Batch-Specific Results
03Each certificate is connected to a specific PP lot number so the report can be matched directly to the batch being displayed.
Original Certificate
04Open the actual laboratory certificate and review the reported results directly.
