Research document checklist | Proof Line Peptides

A record of which documents you actually hold for one vial of research material, and which you do not. Ticking every box does not make material safe, approved, tested or suitable for anything — it records only that certain documents exist and match each other. This page makes no claim about any Proof Line Peptides product.

1 · Identity

What the material is said to be, in writing, independent of the listing name. A product name is a label, not an identity statement.

Compound name as written on the vial label
Stated sequence, or a written note that no sequence was supplied
Stated length or fragment status where a name is ambiguous (for example a trade name rather than a sequence designation)
Any stated modification, such as acetylation or a persistence-extending complex
For a blend: each component named, and the ratio if documented
Stated quantity per vial, and whether that quantity is per component or combined

2 · Laboratory report

What was measured, by which method, on which material. Purity, peptide content and biological activity are three separate questions.

Report number or unique identifier
Analytical method named (for example reversed-phase HPLC, mass spectrometry)
Purity result, with the method it is relative to
Peptide content result, if measured at all
Identity confirmation, and by which method
Date the analysis was performed
Whether sterility or endotoxin was tested, or explicitly not tested

3 · Provenance and traceability

Whether the report can be tied to the vial in front of you, and whether its origin can be checked by someone other than the seller.

Lot or batch number on the vial label
The same lot number appearing on the report
Sample identifier on the report matching the lot
Issuing laboratory named, with contact details
Laboratory independent of the seller, or stated as in-house
A way to verify the report directly with the issuing laboratory
Who held the sample between manufacture and analysis, if stated
Storage condition stated on receipt, and how it was shipped

4 · Missing information, named

The most useful line in any record. Write down what nobody supplied, in the same words each time, so gaps stay visible later.

No report supplied at all
Report supplied but for a different lot
Report undated, or dated after the label date
Issuing laboratory not named or not contactable
Sequence not stated
Blend ratio not stated
Peptide content not measured (purity only)
Sterility and endotoxin not tested

Notes

Space for lot numbers, report numbers, dates and the exact wording of anything a supplier declined to state.
