The stuff has zero nutritional value for chameleons. It will keep your crickets alive but you chams unhealthy.
Here is what I posted in another thread about this gutload.
Here are the ingredients I found in the fluker's cricket feed:
Ingredients:
Ground yellow corn, calcium carbonate, soybean meal, wheat middlings, ground soybean hulls, meat meal, fish meal, animal fat preserved with BHA, dicalcium phosphate, salt, dl-methionine, cyanocobalamin (source of vitamin B12), riboflavin, calcium pantothenate, nicotinic acid, choline chloride, folic acid, sodium selenite, pyridoxine hydrochloride, vitamin A acetate, cholecalciferol (source of vitamin D3), dl-alpha-tocopheryl acetate (source of vitamin E), menadione dimethylpyrimidinol bisulfite (source of vitamin K), magnesium oxide, thiamine, cobalt carbonate, ferrous carbonate, copper sulfate, calcium iodate, manganous oxide, zinc sulfate, zinc oxide.
Basically, just a bunch of junk. Yellow corn (Bad), soybean meal ( Likely, GMO soy, Bad), meat meal , ( Bad), fish meal, (Bad), animal fat preserved with BHA (wow, Bad) and on and on. I wouldn't even give it to a care taker watching my crew while on vacation.
Just thought I would toss that out there for you. It's all about reading and understanding the labels and chemistry.
