I think most any of them will do the trick. The main difference might be the fillers, if they use any.
Also, pay attention to the mg/capsule. If the mg is 1000mg/cap, that does not give much room for customization.
A smaller 500mg (or 600mg) gives more options for customized dosage: 500, 1000, 1500, 2000 etc.
Start with a lower dose, like 500 or 600mg. One great advantage to FG is that it makes your pee smell like maple syrup.
I'm not sure that everyone can smell it in their pee, like asparagus. Some people do not have the gene, or whatever it takes, to smell it.
I'm only guessing but if you can smell asparagus in your pee, you will likely be able to smell FG too. Maybe they are not connected?
You know if you are taking enough, if you can smell it. Well, at least it gives you some idea anyway.
