Astra Labs Batch Verification Hub
Find the current batch for each research product first, then open older verification records from the archived batch section underneath.
Match The Code On Your Label
Open the product strength below and compare the batch code on your vial with the listed current or archived record.
Date note: Dates shown on this page are interpreted from the batch code for easier tracking. The external verification record remains the source for the laboratory testing date.

Bundles Use Component COAs
Bundles supplied as separate individual vials should be matched against the COA for each component vial. A standalone Retatrutide 30mg vial uses the dedicated RE30 batch record above.
Current Versus Archived
“Current batch” identifies the newest batch record presently listed for that SKU. Older valid records remain available under “Archived batches”.
- Always match the exact code printed on the vial.
- Do not assume the current batch applies to an older vial.
- Archived does not mean invalid. It means the batch is no longer the newest listed record.
- Contact Astra Labs when a label or batch cannot be matched.
Certificates Of Analysis FAQs
What does “current batch” mean?
It means the newest verification record currently listed on this hub for that exact product strength.
Are archived batches still valid records?
Yes. Archived records are retained so older vials can still be matched to their original batch verification link.
How do I check my vial?
Find the exact product and strength, then compare the printed batch code with the current and archived records shown on the card.
Why does a product show COA pending?
A current batch-matched verification link has not yet been listed for that SKU. The card will be updated when a record becomes available.
Is the batch date the same as the laboratory testing date?
Not necessarily. Dates displayed here are interpreted from the batch code for easier tracking. Open the external record for the laboratory testing date.
Do bundles have separate COAs?
Bundles made from separate vials use the verification records for their individual component batches.
Is a COA the same as medical approval?
No. A COA is an analytical testing record. It is not medicine licensing, prescribing approval or authorisation for human use.
Are Astra Labs products for human use?
No. Astra Labs products are supplied strictly for laboratory research purposes only.
