Why do some people insist on ruining a good steak by either over cooking it or putting sauce on it? It's a travesty!
That's what I truly believe...but, that doesn't help you...so, hmmm...what if you look at the ingredients in each bottle? Then, whatever is in the A1 that the HP is lacking, if you can find those ingredients, you could add the missing ingredients to your HP. Worth a try? Maybe.
