Components
A blend is only as pure as its weakest component, so the purity at the top of this certificate is the lowest of the figures below, never an average.
| Component | Declared share | Purity | Ion | Observed m/z |
|---|---|---|---|---|
| GHK-Cu | 71.4% | 99.20% | [M+H]+ | 402.83 |
| BPC-157 | 14.3% | 99.50% | [M+H]+ | 1420.57 |
| TB-500 | 14.3% | 99.51% | [M+H]+ | 889.97 |

The vial this covers
The label on your vial carries the same batch code as this certificate, IP-GL-261001, and the QR goes to the results for it. If the code on the vial is not this one, the certificate for it is on this page under earlier batches.
Sticker shown at its printed size, 40 by 20 mm. Cap colour may vary by batch.
