That's too broad of a question, and you're asking about two esters that are on totally different ends of the spectrum as far as release. Chances are, you don't wanna mess with the suspension, especially if you are new to AAS. Like the other poster said, you'll be taking the water based daily and the sustanon twice a week. The aquatest will give you 100mg of test for every 100mg you take of it, while the sus will give you about 75-80mg of test for every 100mg you take. Side effects much more controllable on the sustanon, levels more even, results smoother and more drawn out...overall, better drug for bodybuilding purposes. If you need quick results for some reason (an actual reason such as competition or such, not impatience and desire for a lazy "quick fix") or you need to be able to take something that's gonna be out of your system quickly, then the suspension has it's uses, but even in these situations, prop can probably be used as a better alternative. But if you just wanna cycle some test for personal gains, then I'd say take the sustanon.
