Quality & testing
Every batch is analyzed by an independent laboratory before it reaches you. The certificates of analysis are gathered here, batch by batch.
1. Independent laboratory analysis
Every batch is analyzed by Sidechain, an independent third-party laboratory, not by the supplier that produced it, nor by us. Purity is measured by HPLC, a method that separates the peptide from its impurities and gives its purity as a percentage.
2. One certificate per batch
The result is recorded in a certificate of analysis (COA), the laboratory report specific to the batch, published on the product page and gathered here. It covers the batch powder, before it is sealed in the pen.
3. Batch number on the case
Each case carries its batch number: what you are holding links to the certificate that covers it.
Batch by batch
Certificates of analysis
A certificate attests to the identity and purity of the batch tested. It says nothing about a product's effect on you and does not replace the advice of a healthcare professional.
The sealed pen
Each case is sealed under shrink film at Peptiva: if the film is intact, you are the first person to open it. For every product, the team checks the pH of the solution, then the powder is compacted and sealed in the pen, free of air and light, with its pre-measured water syringe.
Pen or vial: the real difference
