International buying guide
This certificate of analysis supplement guide explains what a COA is, who issues it, what to check and how to spot a weak one. A certificate of analysis for a supplement is the closest thing to a receipt for what is inside a bottle. It also shows how Geroprotect publishes its raw-material certificates so you can check the identity and purity of the raw materials they cover.
What a certificate of analysis for a supplement is
A certificate of analysis is a report tied to one batch of a finished product or one lot (a single production quantity) of raw material. It records what was measured, the result, the method used and the date. In plain words, it is the paperwork that should match the label. A careful buyer reads it the way they would read an ingredient list on food. For an international buyer who cannot hold the bottle before ordering, the certificate is often the most practical way to check a product.
Many certificates come from a manufacturer's or raw-material supplier's own testing. On this store, we publish those source documents so you can read them. They are not independent third-party laboratory reports unless a document names such a laboratory.
What to check on a certificate of analysis for a supplement
A certificate usually leads with assay, because that is the number showing how much of a named active is present. Look for a purity or assay result stated as a number, such as a percentage.
| What to look for | Why it matters |
|---|---|
| Identity | Confirms the material is what the label says it is. |
| Purity or assay | Shows how much of the named ingredient is present. |
| Heavy metals | Lists results for lead, arsenic, cadmium and mercury. |
| Microbiology | Reports yeast, mould and bacteria counts. |
| Batch number and date | Ties the report to a production run and shows when it was tested. |
Red flags on a supplement COA
A certificate is only useful when it is complete and readable. A readable certificate is a basic expectation, not a bonus. Watch for these signs.
- No batch number or lot code, so you cannot tie the paper to the bottle in your hand.
- No issuer named, so you cannot tell who did the testing.
- Blurred, cropped or heavily redacted scans that hide results or methods.
- Pass/fail boxes with no actual numbers behind them.
- A test date that is far older than the batch, or one document reused across many products.
How Geroprotect publishes its raw-material certificates
Geroprotect publishes raw-material certificates of analysis on the group's documents page at gero.ae/certificates. These are COA documents from the manufacturer's testing. The page labels each file by what it establishes, for example an archived raw-material record for a single ingredient, and notes which documents are still being checked before publication.
The certificates let you check the identity and purity of the raw materials they cover. The amount of each active per serving is printed on the label and on the formula page. The two Essentials formulas print every active with a defined amount on the label. Essentials I lists 13 actives per labelled serving of six tablets, and Essentials II lists another 13. There are no proprietary blends. For example, Essentials I prints calcium alpha-ketoglutarate at 450 mg and NMN at 450 mg, while Essentials II prints nicotinamide riboside at 480 mg and resveratrol at 360 mg.
These records are for raw materials, not for the finished batch in your bottle, so use them to check ingredient identity and purity rather than batch-level results.

A certificate of analysis supplement checklist
Use this short list before you order.
- Find the brand's certificates and check that they cover the ingredients named on the label.
- Check identity to confirm the ingredient is what the label names.
- Check that the purity or assay result is stated as a number.
- Confirm heavy metals and microbiology sections show results, not only pass/fail.
- Confirm the batch number and test date.
- If a brand does not publish a readable certificate, ask for one before you order.
