You sent a vial to a lab and the result is under the label amount, or the purity is lower than the seller’s certificate. Before posting or contacting anyone, work through this.

## 1. Read what was measured

- **Amount** (mg per vial) and **purity** (percent) are different numbers. A vial can be very pure and still underfilled. [Purity isn’t the same as the right amount](https://peptidecompare.net/learn/purity-vs-amount/).
- Check the lab’s stated uncertainty. Small gaps from the label sit inside normal variation for fill and measurement.
- Confirm the lab tested the compound you think it did, with the method named on the report.

## 2. Rule out your own handling

Note how the vial was stored and shipped to the lab, how long it took, and whether it was sealed. Say so when you post; it is the first thing people will ask.

## 3. Compare with other results

Open the compound’s lab report page from its [price guide](https://peptidecompare.net/) and the vendor’s [review page](https://peptidecompare.net/v/). One low result is a data point. Several from the same batch are a pattern.

## 4. Contact the seller in writing

Send the report, the batch number and the order date. Ask for their batch record or a retest. Keep the reply.

## 5. Share it

- Post it on this board with the lab, batch, date, label amount, measured amount and purity.
- [Submit the report](https://peptidecompare.net/submit/) so it is added to the vendor’s record on the main site.
- If the seller refuses to engage or the product is clearly not what was sold, see **Scam Alerts**.

Keep the tone factual. A measured result with a batch number does more than an accusation.
