This is your 20th cycle and you don't know what Sust and depot does?? Sounds a little weird?
If this is your "20th" cycle. Say 4 a year, so you been juicing for 5 years now and you now what mass???
Anyhow. ... It sounds like your a beginner so I would say 500mg Of Sust a week. When you when you feel frisky Sust 250mg eod for 875mg a week is a good routine.
