Description
Clenbuterol 40mcg — clenbuterol from the manufacturer at 40 mcg. Long-half-life beta-2 agonist (36–48 h) — dose accumulates over several days. Titrate slowly. Cycle 2-on/2-off to preserve receptor sensitivity.
Key Benefits
- Beta-2 agonist — raises basal metabolic rate and lipolysis
- 2-on / 2-off protocol to prevent beta-receptor downregulation
- Titrate slowly — tremors and tachycardia above 80 mcg/day
- Supplement taurine 3–5 g/day and potassium
- Supporting compound — diet deficit does 90% of the work
- Each unit dosed at 40 mcg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: start 20 mcg/day, titrate by 20 mcg every 2–3 days to 80–120 mcg/day. Two-week on / two-week off cycling prevents beta-2 receptor downregulation. Split dose AM + midday — avoid late-day dosing (insomnia).
How It Works
Selective beta-2 adrenergic agonist. Raises basal metabolic rate, promotes lipolysis, mildly anti-catabolic. Increases body temperature and heart rate. Tissue specificity favours fat over muscle at therapeutic doses.
Pharmacokinetics
Plasma half-life approximately 26–36 hours. Daily dosing. Steady-state in 4–5 days. Receptor downregulation develops after 2 weeks of continuous use — hence cycling.
Potential Side Effects
Tremors, tachycardia, cramps (taurine deficit), insomnia, sweating. Tachycardia persistent above 100 bpm — drop dose. Cardiac hypertrophy risk on long runs. Not for cardiovascular-compromised users.
Cycle & Stacking Guide
2-on / 2-off cycling typical, up to 6–8 weeks total within a cutting phase. Stacks with T3 (aggressive) or with fat-loss AAS protocol (test + var + clen). Always with taurine 3–5 g/day and potassium/magnesium supplementation.
Storage & Handling
Store in the original blister or bottle at 15–25 °C, away from direct sunlight, heat, and humidity. Oral preparations lose potency faster if exposed to moisture; keep the desiccant (if included) with the tablets. Keep out of reach of children. For research and educational purposes only.
