A mixture name is a convenient label, but it does not describe the material sufficiently for another researcher to interpret a study. A useful composition statement identifies the components, the amount basis and the source of each piece of information.
Begin with the declared formulation
State whether the composition describes a target formulation, a container label or an analytical result. These can be presented together, but they answer different questions and should have separate column headings.
For a labelled blend, retain the component names used in the underlying document. If fuller structural definitions are available elsewhere, identify their source and explain how they relate to the blend being reported.
The supplied GLOW report describes a nominal 70 mg blend containing 10 mg BPC-157, 10 mg TB-500 and 50 mg GHK-Cu. It identifies lot BLD-09-759 and report MA-BLD-0009, revision 01. Those details anchor the example to a particular document.Supplied GLOW 70 mg report — MA-BLD-0009 revision 01 (opens in a new tab)
This is a transcription exercise using a supplied report, not an independent analysis or authentication of the material. The report’s component labels should not be silently expanded into sequences it does not provide.
Keep nominal and reported amounts side by side
| Component | Nominal amount | Reported result |
|---|---|---|
| BPC-157 | 10 mg | 10.01 mg |
| TB-500 | 10 mg | 10.02 mg |
| GHK-Cu | 50 mg | 49.90 mg |
| Total | 70 mg | 69.93 mg |
The reported component values sum to 69.93 mg. The document describes total active content as calculated from the component assays; do not present that total as a separate direct measurement.Supplied GLOW 70 mg report — MA-BLD-0009 revision 01 (opens in a new tab)
The table reports mass amounts. A mass ratio should not be labelled a molar ratio without appropriate molecular definitions and a stated conversion. Such a conversion is outside this example.
When describing material used in an experiment, distinguish the supplied vial composition from any later experimental mixture. An experiment that combines materials or uses only part of a container needs its own composition record.
Do not make one percentage stand for composition
The same report gives peptide-related purity as 99.18%. Its note says that this concerns resolved peptide-related substances, not the proportion of an individual component within the blend.Supplied GLOW 70 mg report — MA-BLD-0009 revision 01 (opens in a new tab)
A publication should therefore avoid describing the blend as “99.18% GHK-Cu”, or treating that percentage as confirmation of the nominal three-component ratio. Those statements would change the meaning of the reported result.
The supplied report does not give complete peptide sequences for the components. A reproducibility statement can identify that limitation directly while still reporting the documented names, lot and amounts.
Connect the composition table to the study
Give the report identifier in the table caption or methods text, and make clear whether the research team reproduced any measurements. If the study relies entirely on supplied documentation, use wording such as “the supplied report states”.
Check that figure legends and supplementary files use the same mixture definition. An abbreviated blend name may be convenient after the full definition, but it should not become a different formulation elsewhere in the manuscript.
Where multiple lots were used, map each experiment to its applicable composition evidence. Do not average results from different reports into a single apparently universal product specification.
The finished account should let a reader distinguish what was intended, what was reported and what the study actually used, without having to infer missing chemical details from the mixture name.
