The substances Nationals pitcher Gio Gonzalez allegedly received from the South Florida anti-aging clinic Biogenesis and its chief Anthony Bosch weren’t banned by Major League Baseball, according to two anonymous sources in a Tuesday night ESPN report. Gonzalez, who was linked to the now shuttered clinic and Bosch by a Miami New Times report on Jan. 29, has maintained that he didn’t have any contact with Bosch, wasn’t a patient of the clinic and has never used performance-enhancing drugs. Gonzalez was among several current major leaguers, including Alex Rodriguez and Melky Cabrera, who were tied to the clinic in documents cited by the New Times. MLB has been investigating the clinic and players linked to it. According to the ESPN report, Gonzalez was the only player previously identified in the Biogenesis documents who didn’t receive PEDs from Bosch or the clinic. A document cited by ESPN said that Gonzalez allegedly received ”$1,000 worth of substances, but under ‘notes’ are several substances not banned by Major League Baseball: ‘gluthetyn’ (which a source said was a misspelling of glutathione), ‘IM [intramuscular] shots,’ and amino acids.” The ESPN report said that “glutathione is an anti-oxidant” and cited one source that said that the “‘IM shots’ Gonzalez received were ‘MICs,’ a medically dubious but legal combination of methionine, inositol and choline, often used for weight loss.” Gonzalez’s father, Max, didn’t immediately return a message seeking comment late Tuesday. A Nationals spokesman also didn’t immediately respond to a message. General Manager Mike Rizzo has declined to talk about specifically about Gonzalez’s case last ween because of the pending investigation but he expressed a degree of confidence in the left-handed pitcher. Gonzalez’s name surfaced in the Times report, which cited hand-written notebooks kept by Bosch. His name appeared five times, including a specific 2012 annotation that referred to an order of “Zinc/MIC/…and Aminorip” for $1,000. In records later divulged, Gonzalez’s name appears next to a substance called “pink cream,” described as a “a complex formula that also includes testosterone.”
