Yes, I picked up on that to. Unfortunately, photographic Glycin is often spelled (or misspelled) Glycine. If the substance really is Glycine (the medical stuff), it will not work as a reducing agent.

Is Bluegrass being that sneaky? Nahh - well maybe not.

I recently tested some suspected Glycin of uncertain orgin in a Glycin only developer recipe (Agfa 8) and found that it indeed behaved like Glycin. Then just to be double sure, I ran a sample through the mass spectrometer. Glycin!
