All compounds are supplied strictly for laboratory research use.
Every certificate above comes from an independent ISO 17025 accredited lab. No batch ships without one.
The same panel runs on every current certificate. Here is what each test proves.
Reverse-phase HPLC area normalization quantifies the target peptide against every peptide-related peak. Our release standard is 99%+ purity on every batch.
Measures the actual milligrams of peptide in the vial against the label claim, so 10mg on the label means 10mg in the vial.
Retention-time match against a certified reference standard confirms the compound is exactly what the label says.
The lyophilized cake or solution is inspected for color, uniformity, and physical integrity before release.
Every batch is screened for fentanyl contamination. Result on every certificate: Not Detected.
Arsenic, cadmium, lead, mercury, and chromium quantified by mass spectrometry against strict screening limits.
PCR-based microbial detection verifies no bacterial or fungal growth in the vial.
Bacterial endotoxin quantified in EU/mL by the kinetic method, reported on every certificate.
Three ways in, all under a minute.
Type the compound, or the lot number printed on your label, into the library above.
Every product page carries its current and archived certificates, right below the description.
The QR code on the label lands directly on that exact batch, already highlighted.
A Certificate of Analysis is a document from an independent ISO 17025 accredited laboratory that verifies the purity, identity, and quality of a peptide. Every current certificate runs the full 8-assay panel: peptide purity (HPLC), net peptide content, identity, appearance, fentanyl screen, heavy metals (ICP-MS), sterility (PCR), and endotoxin.
Every product page includes a link to view or download the current batch's Certificate of Analysis. You can also request specific COAs by emailing support@placeholdercompany.com with your order number.
Start with Peptide Purity (should be 99%+), then Net Peptide Content (the measured mg against the label claim), Identity (confirmed against a certified reference standard), and the safety panels: fentanyl screen, heavy metals, sterility, and the quantitative endotoxin result. Every row carries its own pass status.
Yes, we partner with ISO 17025 accredited laboratories that specialize in peptide analysis. These independent facilities have no financial interest in our compounds, ensuring unbiased results.
Every production batch undergoes full testing before release. We maintain rigorous quality control with no exceptions: if a batch doesn't meet our 99%+ purity standard, it's not sold.
Email support with your order number and we will send the batch-specific documentation.
