Great Northern Peptides

Why We Test Every Batch

The peptide industry lacks clear standards and consistent regulations. Because of this gap, many retailers operate without proper oversight. As a result, the market is full of mislabeled, underdosed, and low-purity products. Customers deserve better than uncertainty and risk with every order. That’s exactly why Great Northern Peptides is setting the gold standard.

Transparency with Certificates of Analysis

We built our reputation on trust, transparency, and uncompromising quality. Every batch we receive goes through independent testing at Freedom Diagnostics Lab in the USA. This third-party process confirms three key details:

1. The peptide matches the exact compound stated.

2. Purity always exceeds 99%.

3. The dose aligns precisely with the label.

Because transparency matters, we publish every Certificate of Analysis (COA) on our website. You can verify any report instantly through Freedom Diagnostics. In addition, we update results as soon as new batches arrive and are tested. Therefore, our customers always have access to current and verified data.

Going the Extra Mile for Transparency

We don’t stop at testing. Each vial displays its unique COA number, printed directly on the label. This approach eliminates confusion and builds complete confidence in every order. Whenever a new batch arrives, we retest it and reprint updated labels. As a result, your peptides always include the most recent, verified information. In addition, this step sets a new Gold Standard for accuracy and honesty in Canada’s peptide industry.
