What is Clenbuterol?

Clenbuterol is a beta-2 agonist originally developed as a bronchodilator for treating asthma. It was quickly discovered to have powerful fat-burning effects, making it popular in the fitness community.

Unlike steroids, clenbuterol doesn't affect hormone levels or cause muscle growth directly. Instead, it increases your metabolic rate through thermogenesis - literally raising your body temperature and calorie burn.

For women, clenbuterol offers dramatic cutting results without the masculinizing effects of anabolic steroids. However, it does come with notable side effects that require careful management.

Clenbuterol Dosing for Women

Women respond to lower doses than men. Start low and increase gradually.

Frequently Asked Questions

How much fat can I lose with Clen?
With proper diet and exercise, 4-8 lbs over a 4-week cycle is typical. Some women lose more, especially if they have significant weight to lose. Clenbuterol increases metabolic rate by 10-20%, so results depend heavily on your starting point and adherence to diet.
Will I lose muscle on Clen?
Clenbuterol is actually anti-catabolic - it helps preserve muscle during cutting. This is one of its main benefits over pure thermogenics. Combined with adequate protein intake and resistance training, you should maintain or even slightly gain muscle.
Is Clen better than peptides for fat loss?
They work through different mechanisms. Clenbuterol works faster but has more noticeable side effects (jitters, increased heart rate). GLP-1 peptides are gentler and more sustainable but take longer to show results. Many women prefer peptides for longer-term use and clen for short bursts before events.
Can I just take Clen without exercising?
Clenbuterol will increase your metabolic rate regardless of exercise, but results are significantly better with training. The thermogenic effect means your body burns more calories even at rest, but exercise amplifies this and helps maintain muscle.
Why do I feel jittery on Clen?
Clenbuterol is a beta-2 agonist (similar to adrenaline) which stimulates your nervous system. Jitteriness is common in the first few days but usually subsides as your body adapts. Starting with a low dose (20mcg) and increasing gradually minimizes this.
How long does Clen stay in your system?
Clenbuterol has a half-life of 36-48 hours, meaning it stays active in your system for 2-3 days after your last dose. This is why you shouldn't take it late in the day - it will affect your sleep.
