Welcome Hehetymen, unfortunately a Google search will be insufficient to truly know if your MT2 is high quality/purity. Feel free to talk about suppliers outside of this forum please. Although what you copied and pasted looks good, a supplier may legitimately have a >99% purity batch offered once in a blue moon...my guess is that mostly pure peptides are ~98%, give or take some.... Sadly, suppliers must advertise extremely high purity to keep pace. Only way you'll know for sure is after shelling out a $400-$500 for an independent HPLC/MS test.
You'll have to pay for a HPLC/MS test, which can cost hundreds.
You can also ask the company for a test certificate but it could be old or a forgery so the only way to know for sure is to get an independent one done.
