You are jerking your knee without understanding the PRP procedure.
1. PRP was cleared by World Anti Doping Agency in January 2011 after determining there was not any evidence to suggest that there was any performance advantage in such therapy.
2. It is therapy. It encourages the horses body to heal itself. It is specifically used for horses attempting to overcome serious injuries such as tendons and ligaments, bone fractures, spurs and cysts.
3. Nothing is added to the blood. The centrifuge separates the PRP aliquot from platelet poor plasma and red blood cells. Platelet poor plasma may be removed before the blood is returned to the horse but nothing foreign is added.
4. The Hopes case has nothing to do with Sam Kavanagh and Tom Brennan's bottles labelled 'vitamin complex'. They have to do with lee and Shannon Hope and commercially available and registered vitamin and mineral supplements that could be found in the vast majority of racing stables.
What is at issue is whether there has been a bio-accumulation of cobalt from the use of these supplements particularly in conjunction with vitamin B-12 (both contain cobalt and both are added to popular Vitamin and Mineral supplements such as VAM or Hemo-15 by the manufacturer) or whether the level of cobalt in the swab were due to the race day treatment of horses with those commercially available and registered vitamin and mineral supplements.
5. Best Suggestion is dead. We can agree on that but to suggest it is dead because of the use of supplements is wild speculation that you cannot possibly justify.
'Sad caper horse racing when trainers feel they need to being doing this to compete.'
'This' ? What is 'this' to which you refer ? PRP therapy ? Vitamin and Mineral supplements ? What Sam Kavanagh and Tom Brennan did ? Or do you just throw it all into a pot, mix it with ignorance, unsubstantiated innuendo and wild speculation... and stir ?
