Clear ammonia usually means nothing added. However, since there is no ingredient list, I would pass. I tried to find out what was in it and all I found was their filing a change of formulation which listed an ingredient I don;t want to see. Or have a read here http://www.aquariumadvice.com/forum...to-use-avoid-for-fishless-cycling-156038.html
If you do not want to get the Ammonium Chloride, Amazon has real pure ammonia and it has a label.

I needed to buy a couple of dozen heat packs, so I visited a site for folks who breed fish and/or have fish rooms and I discovered they sell ammonium chloride in powder form. It was $8.95 for 500 grams with the basic description "Pure ammonia for “Fishless Tank Cycling” method of setting up new aquariums. 1 tsp will provide approximately 4 ppm ammonia in 100 gallons of tank water." I wlll be dead before I can use that much. I will mix my own liquid from there using my pure ro/di water. That way I can dose it in ml
(I normally dose to between 2 and 3 ppm for a tank but much more for a bio-farm with a bunch of filters.)
Just a quick explanation about ammonia in water. Pure ammonia is a gas. It cannot exist in solid form unless it freezes which requires a temp. of -107.9F. When ammonia is dissolved in water it turns mostly into ammonium. How much of the ammonia in water is in the form of ammonia and ammonium depends on the pH and temp. of the water. If one could add 100% ammonia into water, it would very rapidly convert into mostly ammonium. If one adds 100% ammonium to a tank, some quickly turns into ammonia. The bacteria want ammonia while live plants want ammonium. Most test kits in the hobby measure Total Ammonia which includes both forms. One can remove aamonia from water either by neutralizing/removing only ammonia or ammonium since the total ammonia will rebalance as one or the other is removed. This is why one can cycle a tank by adding either ammonia or ammonium chloride.
