GLP-1 comes from the body and helps regulate blood sugar and appetite.
The ingredients semaglutide (in Ozempic and Wegovy) and tirzepatide (in Mounjaro and Zepbound) copy GLP-1’s effects to treat diabetes or help control weight.
For GLP-1 shots, the FDA advises against using medicine delivered warm or without adequate cold storage, as of September 2026.
Storage needs depend on the product. The label and pharmacy’s instructions matter; there is no cold-storage rule for all peptides.
As of September 2026, FDA reports describe people needing hospital care after errors measuring semaglutide shots made to order.
