The prospects of duplication are definitely on Hensley's mind, hence last week's press release:
The process has been a bit longer than expected but in the long run, over-coming a substantial barrier to entry serves to protect our proprietary formulations in the nausea relief product against competitors' attempts at any improper replications," says Dr. Charles Hensley. "An extremely important key to this product is not only its efficacy but also having the product and its active blends be difficult for competitors to duplicate. By working closely with the manufacturer, we have been able to accomplish this by using a dedicated Rotavap, which has allowed us to scale up our bench formula while keeping the usually water insoluble actives in solution in a way that does not create discomfort in the consumer's the nasal passage."
I suppose they want it difficult, but perhaps not impossible to duplicate. By the same token, it would not only be the Chinese trying but anybody else with the means also, even in the USA or Europe.
What's to prevent any foreign country in Europe and/or Asia from copying the product and flooding the market. Nothing moral,ehical or legal. Furthermore, isn't ZICAM sold to an international market. But, the future distribution is for management to decide.
