| Attribute | Clenbuterol | Tirzepatide |
|---|---|---|
| Category | Controlled Substances | Metabolic & Weight Loss |
| Research Stage | Preclinical | FDA Approved |
| Mechanism of Action | Clenbuterol acts primarily as a long-acting, highly selective beta-2 adrenergic receptor (B2AR) agonist with approximately 1000-fold selectivity for beta-2 over beta-1 receptors at low doses, though selectivity degrades at the higher doses typical of… | Dual GLP-1 and GIP Receptor Agonism Tirzepatide simultaneously activates two incretin receptors: the GLP-1 receptor and the GIP receptor. While the GLP-1 receptor component provides the well-established effects of GLP-1 agonism (glucose-dependent insulin… |
| Half-Life | — | ~5 days (approximately 120 hours), enabled by C20 fatty diacid albumin-binding modification |
| Typical Dose Range | — | 2500 mcg (2.5 mg) starting dose, titrated every 4 weeks through 5000, 7500, 10000, 12500, to 15000 mcg (15 mg) maximum weekly dose |
| Dosing Frequency | — | Once weekly subcutaneous injection |
| Administration | — | Subcutaneous (weekly) |
| Side Effects | Clenbuterol has a substantial side effect profile that can be subdivided by dose level and chronicity. At therapeutic bronchodilator doses (20-40 mcg BID), side effects are manageable but notable: tremor (especially hand tremor, reported by 50-70% of users… | Mild to moderate nausea (especially at initiation), headache, fatigue, constipation or diarrhea, abdominal distension. Injection site reactions. Rare: hypoglycemia, increased heart rate, pancreatitis. |
