I mentioned earlier that companies like Blue Planet, Cutting edge and Humboldt also copied the GH 3-part and that I would still ask the same question: when is a knockoff ever as good as the original? Now I'm not saying the GH line is the cheapest or easiest to use but it's the original, tried and true, most popular 3-part on the market. Why chance it and buy an imitation?
In regards to the fact that 'the numbers are the same', we all know those numbers are guaranteed minimums which may or may not tell you EXACTLY what's in those bottles. The same goes for GH though which could present a problem for all those companies producing a knockoff based on an inexact guaranteed analysis.
