Research compounds, documented lot by lot.

Five things worth a minute of your time.
See the compounds →Purity vs quantity
99% pure does not mean the vial holds 10 milligrams
Purity is a ratio. Net content is an amount. Most listings print only the first.
See the compounds →Testing standards
Purity is the easy test. Three others rarely get published
Residual solvents, endotoxin data and third-party verification are three separate checks.
See the compounds →Endotoxin awareness
Sterile does not mean endotoxin free
Endotoxins survive sterilisation. Two different findings, and most listings report neither.
See the compounds →Lot traceability
A certificate not tied to your lot proves nothing
Most suppliers reuse one document across every order. Match the number on the vial.
See the compounds →Third-party verification
In-house testing is the seller checking their own work
Independent confirmation at an outside lab is a separate offer, and almost nobody makes it.

Every lot documented before you order.
Not a paid add-on, and not sent on request afterwards. A lot-specific Certificate of Analysis, tied to the number printed on your vial.
