I ran a test cycle with sust this past year. It was hard to get my levels even. The problem is that you are wasting the prop and phelyprop until the longer acting esters kick in and even then you're spiking on the injection day from the prop and phenylprop. Sust was designed as a type of timed-release formula. I don't think your levels will be steady state when doing a twice a week of EOD type thing. I found the sweet spot for me was 1 gram, every 8th day. But you could do 750mg too:
prop 90mg days 1-2
phenylprop 180mg day 2-5
isocaproate 180mg days 5-6
decanate 300mg 6-8
inject morning of 8th day.
This way you get the full effect of all the esters with a fairly even distribution over time. Sust is hard to cycle. Especially if you're familiar with the steady, long-acting esters like enanthate and cyp.
From another article:
Now lets say you are doing a prop only cycle and injecting 30mg twice a week. You can see already that is a waste of gear. If you inject 30mg of prop twice a week you are totally wasting your time. You will NOT grow off of this, so you can basically take sus and knock it down to 220mg an amp if you are injecting once or twice a week. 60 mg of phenylprop--Phenylprop is not that much different than prop. You can get away with injecting the phenylprop ester every third day. Anyone that has taken nandrolone with a phenylprop ester knows that it is shorter acting and must be injected twice a week (for example, getwoods powder). If injected twice a week, then lets even cushion the amount, you will have all 120 mg in one week. To recap, so far this is what you get the first week---180 mg of test in your system. If you ask me that was a waste of two amps. That is barely enough to supress the axis, and that is about all you will have happen if you inject 180mg of test per week.
Now lets look at the longer acting esters in sus. 60mg of Isocaproate--Isocaproate will give you a duration of about a week before it is let go. This is not bad, but at 60 mg you are still not getting enough test to make it worth the time. 100mg of Deconate--Here is the daddy of the four esters. This is the same ester that is used in Decca-Durabolin. The deconate ester should really average out at 2 weeks, but has been said to last up to 3. This ester was added at a 100mg dose to balance out the quicker acting esters used in sustanon. If we review one more time, we can see roughly how much test we will have in our body per week when we use sus, and hopefully you can see it is very low. You can pretty much take out the prop and phenylprop until about week 3 or 4, because once the other esters release the test and it gets time to build up in the system, the prop and phenylprop is useless. Not until around week six are you going to get your test levels high enough to do any good, and if you are on a 10 week cycle and start tapering week 8, then your test have been only relatively high for about 2-3 weeks.
