29Two features of this table are consequential and routinely missed. ''Controlled room temperature'' is not a synonym for whatever temperature a room happens to be; it is a specification with a permitted excursion band and a mean kinetic temperature ceiling, and a warehouse that averages 27 °C does not satisfy it. And the definitions of controlled cold and controlled room temperature both build permitted excursions into the definition itself, so a brief departure from the nominal band is not automatically an excursion in the regulatory sense — a distinction developed at [[Temperature excursion]].{{r|usp659}}29Two features of this table are consequential and routinely missed.

+31Storage statements for the compounds covered on this wiki cluster in two groups. Manufactured injectable [[GLP-1 receptor agonist|GLP-1 receptor agonists]] are labelled for cold storage before first use, with an in-use period at higher temperature after first use. Lyophilised research peptides are commonly accompanied by a recommendation of frozen or cold storage for long-term holding and a statement that the dry material tolerates ambient transit, a combination whose physical basis is set out at [[Lyophilisation]] and whose evidential basis is generally absent.{{r|ich_q1a}}
