| Attribute | |
|---|---|
| Category | Metabolic |
| Evidence grade | Strong |
| Also known as | Ozempic, Wegovy |
| Mechanism | Mimics GLP-1 to enhance glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying and act on hypothalamic appetite centres. Fatty-acid acylation extends its half-life to once-weekly dosing. |
| Key benefits | ~15% mean body-weight reduction over 68 weeks in STEP-1 · Improved HbA1c and cardiovascular outcomes · Marked reduction in appetite and food noise |
| Side effects | Nausea and vomiting · Constipation or diarrhoea · Gallbladder issues · Contraindicated with medullary thyroid carcinoma history |
| Half-life | About 7 days |
| Administration | Once-weekly subcutaneous injection (oral tablet also approved) |
| Dosing overview | Label titration from 0.25 mg weekly up to 2.4 mg over 16+ weeks |
| Storage | Refrigerate 2–8 °C; in-use pens may be kept at room temperature per label |
| Legal status | FDA-approved and prescription-only. |

Each comparison below is its own page with the full attribute table, key differences and shared attributes for that pairing. They are grouped by the category the compounds are indexed under.
GLP-1 receptor agonists
Direct comparisons between the incretin-based compounds most often searched against one another.
Metabolic and GLP-1 compounds
Compounds indexed under metabolic use, including the GLP-1 receptor agonists and the smaller fat-metabolism peptides often searched alongside them.
Recovery and tissue repair
Pairings between compounds indexed for healing, connective tissue and post-injury recovery.
Growth-hormone axis
Secretagogues and releasing peptides that act on growth-hormone signalling, compared with each other and with adjacent compounds.
Longevity and mitochondrial
Compounds indexed under longevity, cellular and mitochondrial function.
