Sounds like your set on Mexican Pharm gear. If thats the case, your options are equally bad, regardless of which one you choose. Sure, there are those who have gotten good results from all the products on your list, but, for every proponent, there are at least an equal number of those with negative experiences. You'll save a couple bucks, but you'll get a product that was manufactured with little-to-no quality controls and one that is distributed by a network of people (Mexicans) with absolutely ZERO integrity or concern for anything besides how much they can bilk you for. Lets face it, Mexicans still screw-up water.
If your going to limit yourself to stuff available in Mexico, then my advice is to get Organon Sust or Testoprim-D. If your set on Mex vet gear, stay with Denkall or Fort Dodge (non-Mexican brands).
Furthermore, I believe its prudent to minimize exposure to Mexicans, and Mexican-made products as much as possible. They inheriently believe that their day-to-day objective is to cheat Americans out of as much money as possible. I travel there frequently, so I'm speaking with plenty of experience.
Best of luck
