Overview
Clenbuterol is a long-acting bronchodilator used for asthma in some countries and for horses with airway disease. It is not approved for human use in Canada.
This listing is Zionova Clenbuterol 50mcg Tablets (50 mcg), photographed as we ship it and priced in Canadian dollars.
How it works
Clenbuterol stimulates beta-2 receptors in the lungs, heart and muscle. This opens the airways, raises heart rate and body temperature and increases fat breakdown. Its half-life of about a day and a half lets it build up with repeated use.
Clinical reference
Where clenbuterol is approved for asthma, typical adult labelling is 20 to 40 micrograms twice a day. It has no approved human use in Canada.
