IGF-1 DES lab tests
4 certificates of analysis for IGF-1 DES are on file, from 4 shops and 3 labs. The latest was tested on .
These are certificates shops have chosen to publish, verified for authenticity before listing. Because shops decide which COAs to make public, the set reflects the batches they published rather than every production batch — a selection bias we state openly. What shop COAs show →

Seven checks for any IGF-1 DES certificate
- Batch-matched and independent. The certificate names the lot in your hands and comes from a lab the vendor neither owns nor pays.
- Purity against the range. Read the figure against what other certificates for this compound report. How to read HPLC and mass-spec results
- Mass-spec identity. Only mass spectrometry shows which molecule is in the vial.
- Net content, measured. Purity and quantity are separate questions. Why 10 mg isn't 10 mg
- Endotoxin on the batch. A missing line means not tested, not passed. Endotoxin testing and LAL interpretation
- A lab you can check. Named on the certificate, with a way to verify it. Testing labs we track · Red flags in a certificate of analysis
- What no test shows. A clean certificate says nothing about efficacy, dosing or long-term safety.
