TweetIt is fine to switch from enan to prop, esters are a matter of preference. However, you should run the prop for 2.5 wks after the eq. I would not switch back from prop to enan though because the enan ester will not be as strong in your system by then. Similar esters like cyp and enan it would not matter, but prop and enan would. I would stick with enan for the entire cycle or maybe run prop the last 4 wks, otherwise run prop the remainder of the cycle.
Also, 100mg eod is only 350mg a wk, you should run it at 150mg eod for a total of 525mg a wk.
