Betmiga (Mirabegron) – A New Fat Burner in Fitness and Bodybuilding

What is Betmiga (Mirabegron)?

Betmiga, also known by the brand name Myrbetriq, is a beta-3 agonist originally used to treat overactive bladder. Its primary medical effect is relaxing the bladder muscles, allowing it to hold more liquid and reducing the frequent urge to urinate.

However, due to a surprising side effect—fat burning—Betmiga has gained attention among bodybuilders and fitness enthusiasts. It is often compared to Clenbuterol and Albuterol, two beta-2 agonists, but with milder side effects.

How Does Mirabegron Work as a Fat Burner?

Mirabegron stimulates metabolism by activating brown fat and beige adipocytes, cells that convert energy into heat. This process mimics the effects of cold exposure or intense exercise. Essentially, Betmiga acts as a “mimetic” of physical activity, increasing calorie expenditure even at rest.

Studies have shown that Mirabegron can increase metabolic rate by:

• 7% at 50 mg doses
• 11-15% at 100-150 mg doses
• 13-16% at 200 mg doses

This means regular use can significantly accelerate fat loss.

Benefits for Fitness and Bodybuilding

• Increases metabolism and calorie consumption at rest
• Reduces body fat by stimulating brown fat activity
• Improves insulin sensitivity and lowers triglycerides
• Enhances physical endurance by stimulating type 1 muscle fibers
• Lowers cholesterol and improves glucose tolerance

Mirabegron vs. Clenbuterol/Albuterol

Unlike beta-2 agonists, Betmiga does not significantly increase muscle mass, as it does not directly stimulate hypertrophy. However, it enhances fatty acid oxidation and mitochondrial biogenesis, promoting fat loss and endurance improvement.

Recommended Dosage

For fat loss, athletes typically use 50-150 mg/day, divided into three equal doses to minimize side effects. At doses above 150 mg, the risks outweigh the benefits.

For women, the recommended dosage is 25-75 mg/day.

Combinations with Other Substances

Some athletes combine Betmiga with beta-2 agonists to enhance fat-burning effects. The most common combinations include:

• Mirabegron + Clenbuterol: 50-150 mg Mirabegron + 40 mcg Clenbuterol/day
• Mirabegron + Albuterol: 50-150 mg Mirabegron + 4 mg Albuterol/day

These combinations increase thermogenesis but also pose greater cardiovascular risks. Do not use both oral and injectable forms simultaneously!

Possible Side Effects

• Tachycardia and increased heart rate
• High blood pressure
• Elevated basal temperature
• Insomnia, anxiety, and nervousness
• Tremors and urinary tract infections (at high doses)

Mirabegron inhibits the CYP2D6 enzyme, which can slow the metabolism of certain drugs, including anabolic steroids, enhancing their potency.

Availability and Accessibility

As a relatively new drug, Betmiga is difficult to find on the black market and is available only by prescription. However, due to its potential as an effective and safer fat burner compared to Clenbuterol, its popularity among bodybuilders is expected to rise.

Conclusion

Betmiga (Mirabegron) is an interesting alternative for those looking to reduce body fat percentage. It has a better safety profile than Clenbuterol but requires responsible use. If you are considering using it, thoroughly research the risks and consult a specialist before administration.
