Olympic 100m champion & double gold medalist Marcell Jacobs "nutritionist" who immediately claimed Jacobs transformation was due to him is linked with Italian police investigation 'Operation Muscle Bound' for supplying HGH, testosterone and anabolic steroids.
Jacobs who was not currently in the AIU athlete testing pool rapidly improved his performance from a PB of 10.03s set in 2019, with a SB of 10.10s to take the Olympic title in 9.80s.
Jacobs has improved by 3% in less than 12 months at the age of 26.

Spazzini Jacobs "Nutritionist" T the heart of "Operation Muscle Bound" claims Jacobs increased his muscle mass by 4kg and reduced body fat by 4% in a year they worked together.
3/
Spazzini gained access to drugs by using doctors prescription pads and stamps.
Despite Jacobs not being in the AIU testing pool as he was not seen as a serious contender to the Olympic crown HGH & Testosterone drugs of choice are only dorectly detectable via blood tests.
4/
Before the Olympics concludes there is already overwhelming suspicion around the 100m champion. Although performance may not directlty indicate doping rapid transformations and astounding performances are two big red flags.
5/
Jacobs is now the joint 10th fastest man in history with only Usain Bolt and Trayvon Bromell ranked ahead of him not implicated in any doping scandal as of date.
High performance and late career transformations are both red flags when you keep this company.

@WorldAthletics time for a periodic review of the DSD regulations which currently restrict 46XY female athletes who have testes & testosterone levels in the male range (7.7 - 29.4nmol/L) currently only restricting participation in events over the 400m-1500m.
Thread 1/
The performance benefits of testosterone do not discriminate between running distances.
On average males have a performance benefit of 11.2% (± 1. 25) across all running events & 19.0% (± 2.57) for all jumping events.
The gender gap exists across all running distances as shown by Thibault et al (2010) study showsthe smallest margin in running events of 6.5% in the 100m but the largest difference 13.96% I the 4x100m.
As a rider Gianetti collapsed during the 1998 Tour of Romandie with multiple organ failure after suspected use of a experimental drug PFC (perfluorocarbon) a blood substitute.

Gianetti was Team Manager of Saunier Duval-Prodir Team.
The Saunier Duval-Prodir Team were withdrawn from the 2008 TDF after Riccardo Riccall tested positive for CERA a form of EPO. Later Leonardo Piepoli also tested positive for CERA.
