Verification Field Guide
Lot vs Batch
Numbers.
Two numbers exist for every vial, and vendors use the words interchangeably. They are not the same thing. The batch number belongs to the lab and is the key to the certificate. The lot number belongs to the vendor and is the key to its inventory. Neither is printed on a Forge vial. The cap colour and the listing are.
What’s on the vial. And what isn’t.
A Forge label carries the compound, the strength, and the research-use statement. The batch is identified by the cap colour, resolved on the product page.
01
Compound + strength
Look forCOMPOUND · 10 mg
As on the listing. The first thing to match.
02
Cap colour
Look forThe coloured cap on the vial
The key. Each batch in stock is assigned a cap colour, and the product listing shows a cap-colour chip next to the batch number it belongs to. Match the cap in your hand to the chip on the page.
03
Research use only
Look forFor research use only. Not for human or veterinary use.
Printed on every label. It is a statement about the product’s sale, not a field to verify.
04
What is not on the label
Look forNo batch or lot number
Forge labels are printed in stock runs, so a batch number on the label would be wrong the day the batch changed. The batch lives on the listing and the certificate, where it updates per batch without a reprint. The cap colour is what ties the vial to it.
Two numbers, two owners.
Batch: the lab’s
What it is: the synthesis run the lab tested. One certificate per batch.
Who assigns it: the lab or manufacturer. It is stamped on the certificate.
What Forge does with it: records it exactly as issued. Never reformatted or replaced with an internal code.
Where you see it: on the product listing, next to the cap-colour chip, and on the certificate.
Lot: Forge’s
What it is: a Forge inventory unit: one received order line, filled to vials, one cap colour, one fill month.
Who assigns it: Forge, at receipt.
What it tells Forge: which fill run a vial came from, when, and which batch it references.
The relationship: a lot always points to a batch. A batch may be referenced by more than one lot.
How Forge names a lot.
The lot ID is an internal inventory key. It is shown here so the structure is public, not because you need it to verify a vial.
CMPD10-2608-01-WHT
CMPD
Compound token (example): each product has its own. Blends carry a product token, not an ingredient list.
10
Vial strength in mg, as labeled.
2608
Fill month, year then month: August 2026. Sortable, so oldest stock ships first.
01
Sequence within that compound, strength and month. Resets monthly.
WHT
Cap colour, three letters. The same cap colour the listing shows against the batch.
No source, supplier or facility is encoded in the ID. It describes the vial, not where its material came from.
Blends. One lot, several batches.
A blended vial holds compounds that were synthesized and tested separately. So a blend has one lot (one fill run, one cap) that references one batch per component, and one certificate per component. A single-compound vial is the same model with one batch. The listing for a blend shows a verified claim only when every component’s certificate is published. See how a Forge panel is assembled.
Verify a vial in four steps.
01
Note the compound, strength and cap colour on the vial.
02
Open that product’s listing. Find the batch number and the cap-colour chip beside it.
03
Match your cap to the chip. Open the certificate linked to that batch and match the batch number on it.
04
Note the lab named on the certificate. That lab, not Forge, is who can confirm the batch result.
