Fe- when you say 'no taste/smell', do you mean the capsule from the outside or did you actually cut one up and tasted/smelled the contents. If you haven't, please do so and let us know how foul it was.
GNC?!? I wouldn't take anything they sold if you paid me to do it - utter crap - they're one of the companies snared in Consumer Labs and/or some other DS investigations that showed all kinds of nasty stuff in their products, plus missing ingredients. Appears to be rather high purity, 91% - but is it oxidized? Cut one open and smell it - the sniff test is the best, not lack of fish burps.
