How it works
Sermorelin
Activates the GHRH receptor on the pituitary gland, stimulating the body's own pulsatile release of growth hormone rather than supplying growth hormone directly.
Tirzepatide
Activates two hormone receptors at once — GIP and GLP-1 — slowing gastric emptying, increasing insulin release when blood sugar is high, and reducing appetite.

Every fact above is reused from Sermorelin's and Tirzepatide's own compound guides, not re-derived here. A highlighted value means that number is objectively larger or smaller — more providers ranked, a lower standing price — never a claim about which compound is “better.” Cost and provider counts are read live from each compound's own board and can change without notice.
