Not true.
One year I took half a super off a week after treatment; it tasted of lemon sherbet and had a litmus reading 100 times that of the average ph of honey.
Long email exchange ensued with the CEO in Canada (as I recall) which ended with him saying what sort of company do you think we are? when I asked whether he'd be interested in testing it. Apparently cost was the stumbling block.
By that point they'd already tried to get rid of me by sending an email about a foot long suggesting the honey was fermented. I sent a sample to Thorne and they shared it with a group of experienced beekeepers, who agreed that it was not fermented.
BCWagric, the importers, acknowledged that testing would be useful, but nothing was done.
A while later another renowned beekeeper discovered he had 6 supers of tainted honey. He could do nothing but feed it back the next spring to draw comb. Even at country prices that was £750 worth of honey.
By all means try it with supers, but my experience was 8 years ago and honey has gone up in price since then.
