Yes, I’d really love to hear what Dr. Greger thinks about soy and thyroid. I have Hashimoto’s Thyroiditis, on a low dose of Synthroid to keep my thyroid normal. When my husband and I went completely vegan a year ago (and thus increased our soy consumption greatly), my husband lost 40 lbs, and I gained 6! I also noticed that my thyroid began to slightly swell again. Please Dr. Greger, what do you think? I’d love to be able to eat edemame, and occasionally have some soy meat substitute a few times a week. Thank you.
Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact AAS used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000. 
A useful property of the many benzodiazepine site allosteric modulators is that they may display selective binding to particular subsets of receptors comprising specific subunits. This allows one to determine which GABA A receptor subunit combinations are prevalent in particular brain areas and provides a clue as to which subunit combinations may be responsible for behavioral effects of drugs acting at GABA A receptors. These selective ligands may have pharmacological advantages in that they may allow dissociation of desired therapeutic effects from undesirable side effects.  Few subtype selective ligands have gone into clinical use as yet, with the exception of zolpidem which is reasonably selective for α 1 , but several more selective compounds are in development such as the α 3 -selective drug adipiplon . There are many examples of subtype-selective compounds which are widely used in scientific research, including:
