Is DSIP 5mg third-party tested?
Yes. Every batch of DSIP 5mg is independently tested by a third-party analytical laboratory using HPLC for purity and mass spectrometry for identity confirmation. We never test our own products — the testing lab is a separate entity with no financial relationship to Pepta Labs. Learn how to read a COA.
