Tirzepatide
A dual incretin analogue acting at both the GIP and GLP-1 receptors. High demand and high price have made it one of the most frequently substituted compounds we see, which is why identity confirmation matters as much as the purity number.
What we measure
- HPLC purity (%)
- Identity by LC-MS/MS
- Measured mass per vial (mg)
What tends to go wrong
Commonly substituted with semaglutide or under-filled relative to the label.
This is a pattern we see across submitted samples, not a claim about any particular vendor. The only way to know about your vial is to test your vial.
