Can you take clenbuterol while breastfeeding?

I am pretty sure it is an asthma medicine but I was just wondering because a friend was having trouble finding out.

I breastfeed. Before taking any medication– prescription or OTC, I check with my doctor or a pharmacist. After I found out I was pregnant, I even checked with a pharmacist to see if Tylenol or ibuprofen was okay. I figured it was Tylenol, as that is what I was told after my two-year-old daughter was born, and we have given it to her (children's,of course). In order to keep my daughter healthy, I have to keep myself healthy. In order to keep myself healthy, I have to keep my daughter healthy.

ETA: I lost my baby weight and about 20 pounds more, by eating whole, real foods, (no white/enriched flour, corn syrup, high fructose corn syrup, partially hydrogenated oils, hydrogenated oils, artificial colors, artificial flavors and anything that looks as though it was created in a lab by humans and not in nature by God.) no animals or animal products, and being very active. The same things I did before my first pregnancy.

From what i found online the answer is NO this drug is not ok for breastfeeding mothers
