Quality

How we make it, and how you can check.

The documents behind our quality claims: what each one covers, what it doesn't, and how to get them.

Where the strips are made

Every batch is manufactured in the United States in an FDA-registered facility operating under cGMP (current Good Manufacturing Practice), the same quality system required of serious supplement manufacturers: controlled processes, documented procedures, and batch records for every production run.

Batch testing

Every production run is tested before it ships, and each lot gets a certificate of analysis (COA). The current COAs record appearance and flavor checks, heavy metals (arsenic, cadmium, mercury and lead, tested to USP 233) and microbial limits (including E. coli, Salmonella and Staphylococcus, tested to USP 2021 and 2022). Every result on the published COAs conforms to its specification. A COA is kept on file for every batch we sell.

What the current COAs don’t include is a potency assay: a lab measurement of how much melatonin, magnesium, caffeine or B12 each strip contains. The doses printed on the pack are the amounts each strip is formulated to contain.

Certificates of analysis

The COAs for the current production lots are published here, as issued by our contract manufacturer’s quality team, with lot numbers and dates:

Our contract manufacturer’s identity is withheld from the published copies for confidentiality; everything else is as issued. If your pack shows a different lot number, email support@oprimazestrips.com with the subject “COA request” and we’ll send that batch’s certificate within 24-48 hours. Wholesale partners receive COAs with every order through the partner program.

What’s in a strip

The active doses are printed on every pack and on each product page: 5mg melatonin + 5mg magnesium (Sleep), 40mg caffeine + 250mcg B12 (Energy). The Sleep formula also contains chamomile, saffron, and valerian root (see the Sleep label). The strips are sugar-free. Full ingredient lists appear on the packaging; if you have an allergy or sensitivity question before your pack arrives, email us and we’ll send the complete list for the current batch.

Our standard

We’d rather under-claim and document than over-claim and hope. No invented reviews, no miracle language, just a product made carefully, with documents you can check. Questions we haven’t answered here: support@oprimazestrips.com.
