Stealth Labs Clenbuterol 40 mcg is a pharmaceutical-grade fat-burning compound formulated to support thermogenesis, metabolism, and enhanced cardiovascular endurance. Each tablet delivers 40 mcg of Clenbuterol Hydrochloride, a beta-2 adrenergic agonist widely used during cutting cycles to accelerate body recomposition and improve muscle definition.
Originally developed as a bronchodilator for asthma, Clenbuterol has become a staple in the world of physique enhancement due to its potent fat-shredding effects. By increasing internal body temperature and metabolic rate, Clen helps burn calories even at rest, making it an ideal agent during calorie-restricted phases. According to research published on PubMed, Clenbuterol also shows mild muscle-preserving properties under certain conditions.
Tested on 2025-01-08, Stealth Labs Clenbuterol meets pharmaceutical purity standards and confirms a true 40 mcg dose per tablet. This ensures predictable thermogenic response with every use.
Clen is most effective when used in short bursts or tapered cycles to prevent receptor desensitization. A typical 2-week on, 2-week off approach is recommended.
Due to its stimulant effect, avoid taking Clen late in the evening to prevent sleep disruption. Stack with Taurine to reduce cramping and support electrolyte balance during fat-loss phases.
Stealth Labs Clen pairs well with other cutting compounds to maximize results:
Stealth Labs Clenbuterol is used by both male and female athletes. Women typically stay within the 20–60 mcg/day range to minimize side effects. Due to zero androgenic activity, it's considered one of the few fat burners compatible with female cutting programs.
Common temporary effects include increased heart rate, hand tremors, and night sweats—especially during initial dosing. Always taper up slowly and hydrate properly. Supportive supplementation like taurine and potassium is encouraged for long-term use.
Our store offers lab-tested Clenbuterol from Stealth Labs with guaranteed USA delivery. Products are discreetly shipped and independently tested for purity, giving customers full confidence in quality and dosing accuracy.
Clenbuterol has a long half-life of around 36 to 48 hours, meaning you only need to dose it once per day for consistent fat-burning effects.
Yes, Clen is popular among female athletes. Women should begin at 20 mcg/day and not exceed 60 mcg to avoid overstimulation or side effects.
No, Clen is a beta-2 agonist and not a steroid. It does not affect testosterone, estrogen, or anabolic pathways. It functions purely as a stimulant and thermogenic.
Popular stacks include T3, Anavar, Masteron, or Trenbolone. Always include liver and heart support supplements, and follow a clean diet to maximize results.
