If its in capsule form its likely not raw OXANDROLONE. So I wouldn't be concerned with a lack of taste. Even if it did have one you'd be mostly tasting the fillers/binding agents.
About like you'd expect a piece of chalk to taste like. As far as I've experienced most raws taste the same, exceptions are Clomid (Fucking death. So gross.) and Aromasin (Ever so slightly sour/citrus taste but not in a pleasant way).
Ya. The clomid I've seen is noticeably off-white looking and I had a feeling might taste like shit. Colonial for example uses baking soda as filler... which tastes a bit salty/sour I suppose. I'll dump a Cialis into a couple ounces of water to speed up the process. Can't stay the taste is even noticeable.
