54.79 mg GHK-Cu; 9.50 mg KPV; 9.79 mg TB-500; 11.34 mg BPC-157
Test Method
HPLC with UV detection coupled with mass spectrometry (LC-MS)
What this test measures
High-performance liquid chromatography with UV detection separates the peptide from related impurities and quantifies each fraction. Mass spectrometry confirms molecular identity by measuring the exact mass-to-charge ratio.
Endotoxin Analysis
Limulus Amebocyte Lysate assay in accordance with USP <85>.
Result
✓ Cleared (below threshold)
Sensitivity
≤0.05 EU/mL
What this test measures
The LAL assay detects bacterial endotoxin at the reporting threshold shown. Both replicates must be below the threshold established by USP Chapter <85> to clear. For research-grade material handling only.

Frequently Asked Questions
Quick references for what each test means.
What is HPLC-UV purity testing?
High-Performance Liquid Chromatography (HPLC) separates the peptide from related impurities based on how strongly each molecule interacts with a chromatographic column. A UV detector quantifies each separated fraction, and the total peptide peak area divided by all peaks yields the purity percentage.
What does LC-MS confirm?
Liquid Chromatography–Mass Spectrometry (LC-MS) confirms the peptide's molecular identity by measuring its exact mass-to-charge ratio. This verifies the peptide is what it claims to be — not a related molecule with a similar chromatographic profile.
Why are endotoxin tests run in duplicate?
USP <85> requires duplicate analysis to rule out measurement error. Both replicates must be below the sensitivity threshold (typically ≤0.05 EU/mL) for the batch to pass. Disagreement between replicates triggers a re-test.
Does "Cleared" mean safe for human use?
No. "Cleared" here means the batch meets the USP <85> endotoxin reporting threshold — a standard relevant to laboratory research materials. All products from Oath Research are strictly for research use only and are not approved for human, veterinary, diagnostic, or therapeutic applications.
Are all my orders from this exact batch?
Not necessarily — batches are rotated as inventory moves. Check the batch code on your vial against the test history above to find the matching certificate. Every batch we sell has been independently tested.
Research Use Only
