because sustanon contains both prop and phenyl prop....which when combined, make up a little over 1/3 of the total test in one sust shot. this means that it technically should be injected EOD to see the full benefit of all those different length esters....and to keep stable blood levels. single estered tests are far superior.
it is hard to say because you have not mentioned how far along you are, but your gains are probably from the d-bol jumpstart. sust won't fully kick in until week 4/5...unless you frontloaded.
also, not to flame too much, but it is common practice to ask advice on your cycle and pct plans BEFORE you actually start it, or are midway through.
