Nothing much wrong with the grammar other than an inappropriate question mark and a missing 'It" to commence the next sentence.
The problem with this drug is not performance enhancing? Is that the cocktails of drugs can become masking agents for more sinister happenings.i) The first sentence becomes semantically nonsensical because he appears to be making a statement then adds a question mark at the end.
Is he meaning
"The problem with this drug is that it is not performance enhancing" - in which case he is missing 'that it is'. If that is what he meant to say then re-reading it, it doesn't make sense.
Why is there a "problem" with the drug if it is not performance enhancing? I don't understand. He appears to be saying that those that want to give their horses performance enhancing drugs should use something other than Regumate.
Who is this guy? Some modern day Laurie Connell?
Or does he mean something else?
ii) The second sentence is far worse than you are making out.
He starts with the words "Is that...". We usually start sentences with "Is that..." when we are asking a question e.g. "Is that the way to San Jose?" or "Is that not the way I should be doing things?"
He appears to be making a statement that by giving a horse a cocktail of drugs (which includes Regumate) it effectively becomes a masking agent for more sinister drugs.
If that is what he is saying (very badly) then my question to the forum is anyone aware of this methodology of using a cocktail of drugs, one of which is Regumate, to mask the usage of other drugs?
I notice I haven't got a reply which suggests that either the thread is not being read by the right people, or his statement is bullshit.
I'm no expert in chemistry or horse physiology, but in this day and age of molecular level testing of blood and urine samples you'd think it would be very strange logic to give a horse a cocktail of drugs, then give it a performance enhancing drug thinking that the former would mask the latter.
