Veterinary PED leads to 80 games suspension


Recommended Posts


Mets right-handed reliever Tim Peterson received an 80-game suspension Tuesday after testing positive for a performance-enhancing substance.

Peterson was banned without pay by the Office of the Commissioner of Baseball after testing positive for Trenbolone, a metabolite in violation of the Minor League Drug Prevention and Treatment Program. The Washington native, currently on Class A Advanced St. Lucie's roster, will face suspension effective at the start of the Florida State League season.

Injectable trenbolone acetate was originally adapted for use by bodybuilders from dissolution of Finaplix H pellets, an ear implant used by cattle ranchers to maintain the weight of cattle during shipping to slaughter. Trenbolone improves muscle mass, feed efficiency, and mineral absorption in cattle.

Trenbolone compounds have a binding affinity for the androgen receptor five times as high as that of testosterone. Once metabolized, the drugs have the effect of increasing ammonium ion uptake by muscles, leading to an increase in the rate of protein synthesis. It may also have the secondary effects of stimulating appetite and decreasing the rate of catabolism, as all anabolic steroids are believed to; however, catabolism likely increases significantly once the steroid is no longer taken. Trenbolone has proven popular with anabolic steroid users, as some believe it is not metabolized by aromatase or 5α-reductase into estrogenic compounds such as estradiol, or into dihydrotestosterone; however, studies on this are mixed, with some studies showing a potential increase in both. At least one study in rats has shown trenbolone to cause gene expression with the androgen receptor at least as potent as DHT. This evidence tends to indicate Trenbolone can cause an increase in male secondary sex characteristics without the need to convert to dihydrotestosterone.

Since steroids generally cause virilization effects in women in even small doses, this drug should not be taken by women. Kidney toxicity has been suggested, but has not yet been proven, and scientific evidence supporting the idea is absent from the bodybuilding community that perpetuates this idea. The origin of this myth most likely has to do with the rust-colored oxidized metabolites of trenbolone which are excreted in urine and often mistaken for blood


What it does, Top athletes are still doing this.

Thanks for the info, Mike.

Fortunately for the Mets, this guy has only pitched as high as the Advanced-A level briefly last year, and his big success came a step lower than that (Regular-A, long season.)

I have been touting the potential emergence of the Mets since 2013, asserting that their young, talented starting pitchers that were just starting at the majors and/or at AAA and/or on the verge of getting promoted to the majors would make them a force to contend with in 2015, 2016, and beyond.

If this were Dillon Gee, Zealous Wheeler, Jacob deGrom, Matt Harvey, and/or one of their starting pitchers at the AAA or AA level, it would be a potential big blow to the Mets in the upcoming season.

As it is, it will probably only delay this young hurler's (Tim Peterson) rise through the upper levels of the minors, and perhaps delay his eventual major league career (assuming that he ever gets that far.)
