Clenbuterol is not a steroid or anything like a steroid.
It is a common beta 2 agonist akin to Albuterol, which is very widely used here in the US in both pill form and as an inhaler to combat asthma.
Clen is frowned upon by the FDA because of its long half life in the body. - 10 hours as opposed to Albuterol which clears at twice that rate.
The FDA does not favor orals with long half-lives, but clenbuterol is very widely used in the rest of the world for both Vet & human consumption.
It is still used in the US for equine medication.
Agreed - look at the twitterpation over a beta agonist. Hell, just wait till they find corticosteroids - they will go to a new level of dopiness.
