At Livewell Peptides, all products are independently tested by certified third-party laboratories. Testing typically includes identity confirmation and purity analysis using advanced analytical methods such as HPLC and Mass Spectrometry (MS). Each product is supported by a Certificate of Analysis (COA) to ensure transparency and quality.

Each COA includes the peptide name, batch/lot number, testing methods, purity percentage, and analytical results. You can verify authenticity by matching the batch number on your vial with the corresponding COA listed on our website.

Endotoxin testing is performed on select products where applicable. If endotoxin results are available, they will be clearly indicated on the product page or within the COA.

Most research applications require peptides with ≥98% purity, which is the standard offered by Livewell Peptides unless otherwise stated. Highly sensitive or comparative research may benefit from higher purity levels depending on the protocol.

Unopened peptides should be stored in a cool, dry environment, away from direct light and moisture. For long-term storage, we recommend keeping them refrigerated or frozen at -20°C to maintain stability.

All products from Livewell Peptides are intended strictly for research purposes only. They are not approved for human or veterinary use and must not be consumed, injected, or administered to humans or animals.

Due to the sensitive nature of research compounds, all sales are final. If your order arrives damaged, incorrect, or incomplete, please contact us within 48 hours of delivery so we can assist.
