Research peptides tested by an independent US laboratory to a 99%+ purity release standard, with every certificate published before the lot is released.
Each compound is released lot by lot, only after an independent laboratory report meets the 99%+ purity standard.
Vial size is the catalog specification; measured content is reported on each lot’s COA.

Lot record
Each lot arrives with the manufacturer’s certificate. We file it with the lot and never publish it as proof.
Vials from the lot go to a US laboratory independent of us and of the manufacturer: purity by HPLC, identity by mass spectrometry, content per vial.
The lot is released only if the laboratory’s report shows 99%+ purity. A lot that falls short is not released.
Every vial carries its lot number and a QR code that opens the lot lookup on this site.
The original report goes up at the lot’s permanent address before a single vial ships.
The lot number is printed on the label beside the QR code. The QR code opens this same lookup.
A purity number costs nothing to type. Here is what stands behind ours, and what the category often settles for.
| Standard | Tracegrove | The usual |
|---|---|---|
| Independent testing | Every lot, by a US laboratory independent of us and of the manufacturer | Often unclear who ran the test |
| Report per lot | One report per tested lot, matched to the lot number on the vial | Often one report per product |
| Identity, not just purity | Purity by HPLC and identity by mass spectrometry | Often HPLC purity only |
| Content per vial | Measured amount in the vial, reported separately from purity | Often not reported |
| Release rule | Released only when the report meets the 99%+ purity standard | Often a purity figure with no stated threshold |
| Published before release | The original laboratory PDF, unaltered, before a single vial ships | Often available only on request |
| Records kept | Replaced lots stay published so older certificates can still be checked | Often only the current report is shown |

Three different questions, three different measurements. What each one proves.

From the number on your vial to the laboratory’s own report, in three steps.
ReadFind the lot number printed on the label beside the QR code. Scan the code or enter the number in the lot lookup. You get the record for that exact lot and nothing else.
A US laboratory independent of us and of the manufacturer. Every certificate names the laboratory that issued it and carries its own report ID, so you can confirm it with that laboratory.
It is not released. A lot is released only when its independent report meets the 99%+ purity standard.
No. A report describes one tested lot. Match the lot number on your label to the report.
