For a peptide blend, start with each component and its individual assay. A total vial amount does not tell you the allocation between components; the supplied BPC-157/TB-500 report provides a worked example.
Identify the components precisely
The supplied example is report MA-BPT-0042, revision 01, lot BPT-42-7LP. It describes a 10 mg vial labelled as 5 mg BPC-157 plus 5 mg TB-500. This document explicitly defines TB-500 as Ac-LKKTETQ; preserve that qualification when recording the example.Blend report (PDF) (opens in a new tab)
The report records an LC-HRMS identity conclusion against references. This describes the comparison reported for the submitted material. A familiar blend name alone does not establish the same component structures in another document.Blend report (PDF) (opens in a new tab)
Read each assay before adding
| Component | Reported amount | Stated range |
|---|---|---|
| BPC-157 | 5.02 mg | 4.50–5.50 mg |
| TB-500 (Ac-LKKTETQ) | 4.98 mg | 4.50–5.50 mg |
Both displayed results are within their respective ranges. Their calculated sum is 10.00 mg, with 50.2% and 49.8% of that sum assigned to the two reported component masses. Those percentages are neither chromatographic area percentages nor fractions of all physical material in the vial.Blend report (PDF) (opens in a new tab)
Read “combined” as the report defines it
The report gives combined chromatographic purity of 99.52%, a largest impurity of 0.14% and total related substances of 0.48%. Its trace attributes the combined area to the two target peaks. It does not give 99.52% as an individual purity result for each component.Blend report (PDF) (opens in a new tab)
The individual assays provide the 5.02-to-4.98 mass comparison; combined peak area alone does not supply it. The report also lists related peaks A–F without structural assignments and a 0.03% reporting threshold. Keep unassigned peaks unassigned.Blend report (PDF) (opens in a new tab)
References to duplicate independent preparations do not specify the number of separately selected vials. These values are report transcriptions, not new measurements or independent authentication. Keep the full report, lot and revision with any summary.Blend report (PDF) (opens in a new tab)
