Every worry, answered with proof you can open.
Every claim here points to proof you can open — not our word for it.
What’s on the label, in the vial
Every batch is identity-confirmed by LC-MS and purity-checked by HPLC before it ships, so the compound and purity are verified against the label — for laboratory research use only.
A COA on every batch
Every order includes that batch’s Certificate of Analysis, and the lot on your vial matches the report — so you can check the compound and purity against an independent third-party test.
The tested sample is your vial
The whole batch is homogenized into one solution, machine-filled to a single dose, and sampled across the run — so your vial reads the same as the one tested.
