The ingredient in one breath
GIP and GLP-1 are short names for those two gut hormones. You do not need the long scientific names; what matters is what the hormones do.
Why it is described as long acting
In the Zepbound label, tirzepatide has a half-life of about five to six days. Half-life means the time it takes for the amount in the body to fall by half.
Both approved brands are labelled as once-weekly injections. That is a fact about the products, not a personal schedule.
What the approved products look like
Single-dose vial
A vial can still be an approved brand product.
KwikPen
KwikPen is the maker’s name for its multi-dose pen: one pen that holds four weekly doses. It is listed for both approved brands.
One useful correction
Product, source, and intended use answer those questions. The word alone does not.
