From memory around six or seven years ago there was a lot of interest in active CSL on online forums, and the eagle eyed bait barons jumped on it lol. Just so happened a CSL sourced from Tate n Lyle via a 3rd party became available around this time.

Which having seen the raw untampered with product in the flesh, before the bait industry started re bottling and selling, was a very thick darkish tan colour. Dynamite baits CSL launched around this time, and was strikingly similar and I believe PA stabilised.

I suspect this is the Tate n Lyle CSL, which DNA/BAF are selling on to the public. Roquette was another source for CSL, used in the bait industry. Could be mistaken with all this though.
