No, it's not really similar. Yours has a ratio 50:2, while the AOR ratio is 15:2. I've personally had problems with some of the additional ingredients in Solaray products. I found one Canadian company that does ship to the U.S., but for free shipping you have to buy a lot. Otherwise, s/h is $9.95. Zinc citrate or zinc monomethionate (OptiZinc) is easy to find in 15 mg or 30 mg. Amino acid chelates for copper are hard to find for us. I use TwinLab copper gluconate 2 mg as a default. If you took 30 mg zinc, you'd want 4 mg copper.
