About Pepreta — Australian Research Peptides

Our testing standard

Every batch is analysed before it is dispatched, using three complementary methods:

• HPLC testing — reversed-phase High-Performance Liquid Chromatography verifies compound identity and quantifies purity as a percentage. Our specification is ≥ 99.0%.
• Mass spectrometry — confirms the molecular weight of the peptide matches its theoretical value, verifying identity independently of HPLC.
• Endotoxin testing — LAL screening checks bacterial-endotoxin levels. Low endotoxin matters for the integrity and reproducibility of in-vitro research.

Our documentation

Every batch we dispatch has a Certificate of Analysis showing the actual test results for that specific lot — not a generic certificate. The COA linked on each product page reflects the batch you receive.

Research use only

Pepreta products are supplied exclusively for in-vitro laboratory and research use. They are not approved for human or veterinary use and are not therapeutic goods. We include this framing not as a legal formality but because it reflects how our products should be used.

Why Australian

A locally based Australian supplier means domestic express shipping, local support, and faster, more reliable delivery within Australia. We ship from Sydney & Melbourne.
