just based on what your saying bro I’m gonna guess this is a first cycle?
also, in another thread you were asking about tren and test to cut for a comp? If you have a comp coming up then sust is a horrible choice, especially at a higher dose. Dbol isn’t ideal either.
basically in regard to how much you should use, the aim is always to use the lowest possible dose to elicit the response needed, if you can grow on 350mg test then only use that until you no longer grow on it etc. Everyone responds different, some guys respond great to low doses and others need higher doses, but always start with low as if you can get away with it clearly it’s far healthier (and cheaper)
At 750mg test and 50mg dbol a day estrogen is the main thing to look at, probably gonna be very high. No idea if you currently use a ai but imo most people would need to on that stack. Obviously bloods will help to confirm.
in terms of injection frequency, imo the only real reason to use sust is to reduce the injection frequency, if your pinning 2x week or more personally I would just use cyp or e. If your on trt or you blast and cruise it makes less difference but if your actually cycling and will come off everything at some point then sust takes a very very long time to clear during with time your natural production can’t restart
