Trenbolone is very androgenic and although it is classified as an anabolic it is more androgenic than most testosterones. Trenbolone is a very interesting drug because it does not aromatize into estrogen at all. The advantage of this is of great value because it means that there is no water retention. Trenbolone does however have an affinity for the progesterone receptor. The side effects of progesterone are similar to that of estrogen. Progesterone causes negative feedback from the HPTA axis and therefore suppresses endogenous testosterone production
40. "Wholesaler" means a person who in the usual course of business lawfully supplies narcotic drugs, dangerous drugs, precursor chemicals or regulated chemicals that he himself has not produced or prepared, but not to a person for the purpose of consumption by the person, whether or not the wholesaler has a permit that is issued pursuant to title 32, chapter 18. Wholesaler includes a person who sells, delivers or dispenses a precursor chemical in an amount or under circumstances that would require registration as a distributor of precursor chemicals under the federal act.
In February 2017, American triathlete Beth Gerdes was given a 2-year suspension for presence of ostarine, and American triathlete Lauren Barnett was given a 6-month suspension for the presence of Ostarine. Both triathletes claimed contamination from salt tablet supplements. Lauren Barnett was able to provide tablets and sealed bottle tablets which both tested positive for contamination, thus only the 6-month suspension. The 2-year suspension still stands for Beth Gerdes who provided tablets for testing, but tests showed only low levels of ostarine not high enough to confirm the finding.
