1- Sorry ,but WADA is a US org and Us opinion on matters does not equal absolute truth, since there were not enough scientific data shown for the ban and it was likely more political move.
The drug was invented in the mid-1970s at the Institute of Organic Synthesis of the Latvian SSR Academy of Sciences by Ivars Kalviņš.[84][85][86] Kalviņš criticized the ban, saying that WADA had not presented scientific proof that the drug can be used for doping. According to him, meldonium does not enhance athletic performance in any way, and was rather used by athletes to prevent damage to the heart and muscles caused by lack of oxygen during high-intensity exercise. He contended that not allowing athletes to take care of their health was a violation of their human rights, and that the decision aimed to remove Eastern European athletes from competitions and his drug from the pharmaceutical market.[87][88] Liene Kozlovska, the head of the anti-doping department of the Latvian sports medicine center, rejected claims that the ban is in violation of athletes' rights, saying that meldonium is dangerous in high doses, and should only be used under medical supervision to treat genuine health conditions. She also speculated that Russian athletes may not have received adequate warnings that the drug was banned – due to the suspension of the Russian Anti-Doping Agency in late 2015.[89]
Forbes reported that anesthesiology professor Michael Joyner, at the Mayo Clinic in Rochester, Minnesota, who studies how humans respond to physical and mental stress during exercise and other activities, told them that "Evidence is lacking for many compounds believed to enhance athletic performance. Its use has a sort of urban legend element and there is not much out there that is clearly that effective. I would be shocked if this stuff [meldonium] had an effect greater than caffeine or creatine (a natural substance that, when taken as a supplement, is thought to enhance muscle mass)."[90] Ford Vox, a U.S.-based physician specializing in rehabilitation medicine and a journalist reported "there's not much scientific support for its use as an athletic enhancer".[91]
Don Catlin, a long-time anti-doping expert and the scientific director of the Banned Substances Control Group (BSCG) said "There's really no evidence that there's any performance enhancement from meldonium – Zero percent".[92]
2- Probably you are right about suppression, but sports doctors told me it is one of the safest courses out there if done under supervision and with quality products.
3- English is not my first language, but i think you got my point.
If you look at how drastically results improved in the Olympics, it is naïve to think, it's only due to improved training, and natural supplements.
MMA also show, that guys on TRT and caught on roids have huge advantage.
TRT - Belfort, Hendo.
Roids - Jones, Lesnar, etc.
4- Every rule has exceptions. It was proven, that sleeping under 7 hours has a lot of negative effects and is real bad for general recovery.
And don't give me that Arny bullshit, about sleeping 5-6 hours and training for that much and being ok, sunce he was on horses roids ( see point n3)
I also have a buddy , who eats mostly junk food and sweets and drinks beer and he is more ripped than me on a diet ( we were training equally in one gym for 6 years).
If you see 1-2 exceptions, that doesn't mean you can recommend to eat sweets, junk food and drink bear every second day to be in good shape to every individual.
