Why testing matters
A label is just a sticker. Testing shows what's actually inside.
Key tests for peptides:
🔬 HPLC: checks PURITY (how much is the real peptide?)
⚖️ Mass spectrometry: checks IDENTITY (is it the right molecule?)
🦠 Endotoxin test: checks for bacterial toxins
💧 Sterility test: checks for live germs
📄 A Certificate of Analysis (COA) is a report of these results.
But ask:
✔️ Was it tested by an independent lab, or by the seller?
✔️ Does the batch number match the product?
✔️ Is the lab name real and checkable?
No proper testing = no way to know what you're getting.
