It is more of a preference thing. If you want minimal bloat go with prop, however, realize that you have to inject eod. Cyp and e are pretty much the same though some will say bloat is more on cyp. Other than that they are pretty much the same so whatever you can get that is cheaper go with.

Usually people that are newer to the game go with a long actin ester like cyp or e simply because it is injected less.

Like i said, it is pretty much a personal decision. From what i get from it, results from the tests will pretty much be the same and the water will go down. However, prop may have slightly "cleaner" gains but really i would just go with what you want
