Yes I think it is, though I just bought some from eBay while the going was good. Though eBay sales should be compliant. Message from a moderator spoke of name & address require and being 18yrs or older, which fits eBay rules but not over the counter sales. I also think that as a ingredient in a branded product it drops off the radar.Yeah I think that's just Ebay's policy
Hope is so, did a a quick on line search found only suppliers willing to deal with limited companies not individuals. Many sites indicated pot nitrate for sale but search engines only hit on 'nitrate'. With a friends network there are opportunities for work arounds but relations are getting tighter on many useful reagents ie stuff that works. Could you please send me a link to a dealer that sells pot nitrate to individuals.
