Start with the exact material
A compound name is not a full storage specification. Record the supplier's product, supplied form, formulation where known, packaging and lot. A dry lyophilized preparation and a solution pose different documentation questions.
The first records in our storage lookup are explicitly supplier-specific examples for dry BPC-157 and MOTS-c materials. They are not instructions for all products sharing those names and do not supply a solution shelf life.

Separate conditions from a time claim
An instruction about temperature or protection from light is not the same as a measured period over which defined attributes remain within specification. To evaluate a duration claim, ask which attributes were monitored, by which methods, and under what container and environmental conditions.
ICH's stability framework illustrates why storage and packaging conditions belong in the evidence record. It should not be used to invent a shelf life for a research product that has not been documented under an appropriate study.

Do not fill gaps with generic rules
A convenient rule from a different compound, solvent or formulation is not direct evidence for your material. If a source omits the time period or chemical state, preserve that omission. If supplier instructions conflict, ask what products and data each statement covers.
Avoid treating an intact-looking vial or a familiar appearance as analytical evidence. A physical observation can raise a question, but it cannot replace a suitable measurement of the attribute of concern.
A record worth keeping
For an educational reference, retain the compound identity, product source, material state, stated conditions, duration if actually documented, packaging context, source link and date checked. Mark whether the source is an instruction, a technical study or an unverified marketing statement.
This makes updates practical. A changed product instruction should be recorded as a changed instruction; it should not silently rewrite a previously published experimental finding.
Questions, answered.
Does a −20 °C instruction establish a one-year shelf life?
No. A stated condition does not establish an unstated time period.
Can dry-powder storage advice be applied to a solution?
Not without evidence for the solution's exact formulation, conditions and relevant time period.
Why does the storage lookup sometimes say not established?
It means the reference does not contain a reviewed record for that selection. It is not a claim that no evidence exists anywhere.
