Usually the RUI products don't taste bad. I've used ************ and UG liquid stuff that tastes like pure rubbing alcohol but RUI does a good job at masking the chemical taste.
On another note, I've always said if possible, go with Aromasin over Adex if possible. And this is only because of the negative effects Adex can have on your lipids. Even at a pretty lose dose, it will have some negative effects. At higher doses it basically destroys them. I have to unfortunately run Letro during all my cylces, as its the only thing personally, that works for me, I have gyno flares from test, and Adex/Aromasin don't do the trick. I can only imagine what my bloodwork will look like after running Tren and Letro alongside it for so long. Just my 2cc, stay healthy.
