Certificate terms
What does “mg/unit” mean on a COA?
Short answer
mg/unit means milligrams per unit: the amount the laboratory measured in one unit of the sample it was sent. On Clean Peptide's lot pages it appears once, for BPC-157 20 mg, lot ACE-0594510, where Accurate Test Labs reports 20.99 mg/unit of BPC-157. The certificate does not define the unit; it lists the sample type as a vial and the labelled content as 20.
How each certificate gives the measured amount
| Laboratory | Unit printed | Example | Figure |
|---|---|---|---|
| Accurate Test Labs | mg/unit | BPC-157 20 mg | 20.99 mg/unit |
| ILS Laboratories | mg (Net Peptide Content) | TB-500 10 mg | 10.31mg |
| HYTE Research Division, vials | mg (Net Quantity) | KPV 10 mg (certificate) | 12.94mg |
| HYTE Research Division, sprays | mg/mL | DSIP Spray 20 mL | 1.18mg/mL |
| HYTE Research Division, Selank Spray | mg for the bottle | Selank Spray 20 mL | 19.69mg |
| Laboratory not named on the lot page | mg (Quantity) | Epithalon 10 mg | 10.44 mg |

On the BPC-157 20 mg certificate the figure sits in a "Peptides" section: BPC-157, 20.99 mg/unit, status Tested, and a total of 20.99. The same certificate gives purity as 99.8% and identity as confirmed. Against the 20 mg label, 20.99 is 105.0%.
The units differ by laboratory. For the freeze-dried vials, both are a weight of peptide: ILS Laboratories prints plain mg against a labelled content of 10mg on TB-500, and Accurate Test Labs prints mg/unit against a labelled content of 20. For the sprays, mg/mL is a concentration; the bottle holds 20 mL.
