We do not tell the lab what we are sending. They identify and verify the compound independently.
Our Process
From Manufacturer to Your Lab
Supplier Verification
We work exclusively with GMP-compliant manufacturers who have a proven track record for producing research-grade compounds.
Initial Testing at Source
Products undergo comprehensive analysis before leaving our supplier, including purity testing, identity verification, and contamination screening.
Blind Testing via PepScan Australia
We send every product to PepScan Australia laboratory without disclosing what compound it is. The lab identifies and verifies the substance independently, ensuring unbiased results.
Verified COA Issued
Each product ships with a PepScan Australia-verified Certificate of Analysis showing test results, purity levels, and batch info. No fakes, no copies from other batches.
Testing Methods
How Purity is Verified
HPLC Analysis
High-Performance Liquid Chromatography confirms compound identity and measures purity with precision.
Mass Spectrometry
MS analysis verifies molecular weight and structure to confirm you receive exactly what is labelled.
98%+ Purity Standard
All peptides must meet or exceed 98% purity. Products below this threshold are rejected.
Contamination Screening
Products are tested for bacterial endotoxins, heavy metals, and other contaminants.
