Reading a COA
What every certificate tells you.
A Skye Peptides Certificate of Analysis isn't marketing â it's raw data from the testing lab. Here's what each metric actually means.
HPLC Purity
High-Performance Liquid Chromatography separates your peptide from any impurities. The result is a percentage â we publish it exactly as the lab reports it, down to the decimal.
Mass Confirmation (MS)
Mass spectrometry confirms the molecular weight of the peptide matches the expected sequence. If it doesn't match, the batch fails and never ships.
Sterility Testing
Each batch is cultured to check for microbial contamination. A "pass" means no detectable bacterial or fungal growth under standard test conditions.
Endotoxin (LAL)
Limulus Amebocyte Lysate testing measures bacterial endotoxins. Our limit is â¤5 EU/mg, and most batches come in well below 0.2 EU/mg.
Heavy Metals
ICP-MS analysis for lead, arsenic, mercury, and cadmium. Ensures no residual metal contamination from synthesis or handling.
Batch Traceability
Every COA is tied to a specific batch number printed on your vial. You can verify that the certificate you're reading is the exact lot you received.

Our Testing Protocol
Four gates before any batch ships.
Every Skye Peptides batch passes through the same rigorous testing sequence â regardless of compound, quantity, or destination.
đ§Ē
1. Synthesis
Solid-phase peptide synthesis in our U.S. facility using pharmaceutical-grade reagents.
đŦ
2. HPLC Purification
Every fraction purified via HPLC. Only lots at âĨ99% purity advance to third-party testing.
đ
3. Independent Analysis
Batch samples sent to Janoshik, AccuMark, and other ISO-accredited labs for full panel testing.
đ
4. Public COA
Batch-specific certificate published to this page, downloadable by anyone, forever.
