How we protect your research supply

Quality is defined before shipment—and supported after delivery.

We do not rely on vague promises. The accepted quotation and written supply confirmation define what is being supplied and the quality specification against which a claim can be assessed.

Qualified manufacturing supply network

Six Peptide Bio coordinates sourcing through qualified manufacturing partners. We keep specifications, documentation, packaging requirements and lead times clear from inquiry to delivery without representing partner facilities as our own.

Specification-led quality

Every supply starts with written confirmation of the product, variant, quantity, packaging, documentation and applicable quality specification. This confirmed specification becomes the basis of our quality guarantee.

Freedom / Janoshik testing covered

Customers may submit qualifying samples to Freedom or Janoshik Analytical. If the complete report confirms that purity or endotoxin does not meet the specification agreed before supply, the affected goods and reasonable relevant testing fee are covered.

Goods compensation guarantee

For a verified purity or endotoxin failure, we replace or compensate the affected goods and reimburse the reasonable testing fee. Our technical team confirms the remedy and logistics during claim review.

Product & quantity guarantee

Before dispatch, we reconcile the product, variant or specification, declared content, batch label, package count and total confirmed quantity against the accepted quotation. A verified shortage, wrong product or wrong specification is made up or replaced at no product charge.
