Peptides are independently tested for purity. Verified COAs are available in our COA Library.
Quantifies every component in the sample
Confirms the exact molecular structure
Analytical documentation available in our COA Library
One test tells you how pure it is. The other confirms it’s the right molecule. Both are required. Neither is optional.
Purity without documentation is a marketing claim, not a measurement. Before ordering from any supplier, these are the questions that reveal whether they operate to a research-grade standard — or just say they do.
| Question | Typical Supplier | Supreme Biogenix Labs |
|---|---|---|
| Is purity tested by HPLC analysis and documented? | Often no, or unclear | Yes |
| Is molecular identity confirmed by mass spectrometry, not HPLC alone? | Frequently omitted | Yes |
| Is the COA available on request and delivered within 24 hours? | Slow or unavailable | Yes |
| Are products lyophilized and stored correctly, or shipped as liquid solutions? | Liquid formats used | Lyophilized |
| Can you verify the testing lab is accredited and operates independently? | Lab often unverifiable | Yes |
"Lyophilized peptides stored at −20°C in sealed, desiccated vials maintain structural integrity for 24+ months. Lyophilization eliminates moisture — the primary driver of peptide degradation — for maximum long-term stability."
Do not open vials until needed for research use. Moisture exposure begins degrading lyophilized peptides immediately.
UV exposure can induce photodegradation. Store in dark or amber conditions at all times.
Repeated freeze-thaw cycles reduce peptide integrity. Maintain consistent storage conditions throughout the research period.
All peptides are strictly for in vitro laboratory research. Refer to peer-reviewed sources for research protocols specific to each peptide.
