Characterization of trenbolone acetate and estradiol metabolite excretion profiles in implanted steers.
Blackwell BR, Brown TR, Broadway PR, Buser MD, Brooks JC, Johnson BJ, Cobb GP, Smith PN. Blackwell BR, et al. Environ Toxicol Chem. 2014 Dec;33(12):2850-8. doi: 10.1002/etc.2757. Epub 2014 Oct 20. Environ Toxicol Chem. 2014. PMID: 25244153
