Is Clenbuterol a non-hormonal drug?
This was the pitch with Clenbuterol: it was supposed to be a repartitioning agent, not a hormone. I guess the idea came from the fact it was not a steroid and not related to testosterone in any way. Many drug free bodybuilders bought that idea and started using drugs with the help or because of Clenbuterol. Clenbuterol is indeed very closely related to hormones called catecholamines. The best known catecholamines are adrenaline and noradrenaline (a.k.a epinephrine and norepinephrine). So, taking Clenbuterol is a bit like using those hormones except that Clen acts mostly on beta adrenergic receptors and not on alpha adrenergic receptors. Adrenaline and noradrenaline act on both kinds of adrenoceptors. Clen is therefore a beta agonist (beta 2 to be more specific).
