Peptide Half-Life Reference Guide
A published half-life belongs to the study that measured it. It is not an administration schedule. 21+. Research only.
A half-life is not a schedule
Papers on GLP-1SG (semaglutide in the literature) and GLP-2TZ report exposure in specific models, doses, and assays. Those numbers stay inside those papers. This page will not turn them into a calendar.
Half-life depends on the model, the route used in that study, the assay, and what was actually measured. A plasma figure from one species does not become a handling instruction for a lyophilized vial.
Use the number to find the paper
If a review quotes a half-life, open the study it cites and read the methods. Write down the model and the unit. If the paper does not match the compound on the label, the number does not travel with the vial.
GLP-1SG 15 mg is $54.99. GLP-2TZ 15 mg is $64.99. They are separate listings with separate COAs, task 155227 and task 171262.
