Analytical Testing Methods
At Paragon Peptides, we utilize High-Performance Liquid Chromatography (HPLC) to verify the purity of every batch, ensuring it meets the ≥99% standard required for high-tier laboratory research.
Why HPLC Matters
HPLC allows researchers to see the "fingerprint" of a compound. A single, sharp peak on the resulting chromatogram indicates a high-purity substance, while multiple smaller peaks suggest impurities or degradation that could compromise your research data.
In addition to HPLC, we employ Mass Spectrometry (MS). While HPLC tells us how pure a peptide is, MS confirms the molecular weight, ensuring that the [Retatrutide](https://paragonpeptides.net/product.html?id=111) or [Tirzepatide](https://paragonpeptides.net/product.html?id=112) in your vial is exactly what was synthesized.
Standardization Protocol
- Independent third-party verification for every lot number.
- Endotoxin testing to ensure pyrogen-free material (< 1.0 EU/mg).
- Strict stability testing under various temperature conditions.
