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.
- 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 and the vendor’s review page. 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 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.
