— Common Questions
Got questions.
Why does Merit ship lyophilized?+
Lyophilized format gives ≥24 months sealed stability at -20°C — significantly longer than pre-reconstituted, which has a 30-day shelf life once in solution. You reconstitute at the moment of use, when potency is at its peak.
How do I check the certificate for my batch?+
The QR code on every vial opens our COA library. Search by compound to find the certificate for the batch currently shipping. No account and no request form, and the library keeps every certificate we have released.
What does "independently assayed" actually mean?+
Every batch is tested by a laboratory independent of the facility that made it, and the certificate is published before the batch is listed. You read the same identity and purity figures we do — that's what separates Merit from a reseller catalog.
Will my bank flag this purchase?+
Statements show as Merit Sciences LLC. Standard merchant descriptor — does not trigger category-code flags. All major cards and PayPal accepted at checkout.
How fast does it ship?+
48 hours from order to dispatch, Monday through Thursday. UPS Ground, tracked + insured. From San Antonio, TX, most US addresses receive within 3-5 business days.
