i got some of the footballs (1mg) a week or so ago and did em sublingual - they burned in an odd way;not like habanero, not like wasabi, not like being set on fire or maced, but a definite burning sensation. they were blue generics, dont remember the stamp. ive a feeling that this is to discourage insufflation as it was unpleasant enough in my mouth. the bars (2mg, 3 score marks) dont do this. i eat them on an empty stomach anyway,bioavailability is probably within a few % points snorted, sublingual or eaten.
