Description
At Archer Peptides, we set the standard in transparency paying for our products to be randomly tested by one of the top labs in the country.
Our products are tested for identification and purity ensuring we purchase and sell the highest quality Peptides to our research customers.
We deleted all our Coa’s from 2025 and continue to have new lab tests performed throughout the year.
June 2026, we are having the famous “Wolverine Stack” (BPC157+TB500) and IPAMORELIN tested.
Here are the key components of a Peptide COA:
-
- Identity (Mass Spectrometry): Confirms the peptide sequence matches what was ordered (molecular weight).
- Purity (HPLC): Measures the percentage of the target peptide relative to impurities, typically reported as a percentage (e.g., \(\ge98\%\)).
- Net Peptide Content: Specifies the actual amount of peptide in the sample, excluding counter-ions and water.
- Contaminant Testing: Details levels of impurities such as residual solvents, endotoxins, or heavy metals.
Why a COA Matters
-
- Quality Assurance: It ensures the peptide is not “fake” and meets research standards.
- Reproducibility: Confirms that the material used is consistent between experiments.
- Safety Check: Identifies potentially harmful contaminants.
What to Look For
A legitimate COA should be generated by an independent, third-party laboratory to avoid conflicts of interest. It should be lot-specific, meaning it applies to the exact batch purchased rather than a generic report.
