01

06

Direct lab contact

Questions about a result go straight to the testing lab, not a support script.

Questions researchers ask

Is it legal to purchase these compounds?

Yes, for laboratory research use by qualified purchasers - every product is sold strictly for in-vitro research, not for human or animal consumption. See the disclaimer below.

How should a vial be stored on arrival?

Lyophilised vials keep best refrigerated or frozen until reconstitution. We don't provide dosing or administration guidance - that's outside a supplier's role.

What does a COA actually verify?

Identity and purity via HPLC/MS, run by an independent lab with no financial stake in the result, plus a contaminant/endotoxin screen.

Can I order several compounds at a discount?

Yes - see the kit builder above. Five or ten compounds across the catalog, discount applied automatically at checkout.

What if a lot's COA doesn't match what I test internally?

Contact the testing lab directly - see "Direct lab contact" above. We'd rather you verify this yourselves than take our word for it.
