I think you are going to have a decent amount of test still in your system for several weeks after your last week on.
I don’t have time to figure out the exact amount considering the half lives but the deconate has a half life around 2 weeks I believe. You might want to figure it out so you will know when to start PCT. And to know when your actually on and off.
That’s fine but see to that you use sust 250 ant not 100mg also you need to run the sust for at least 6 weeks before you urn to winny.You could however stop D-Bol in about 5 weeks.You could rather go in with sust 100 for 3 days alternating with sust 250 for thre days with one day off in bewtwen thois way you will have the long lasting test deanoate ester in your system and also maintain the levels on short acting phenylpropionate and propionate esters in your blood.I have done this and seen amazing results.Since ya on D-bol and Sust keep your diet high in protein,Qualtiy Carbs and low in Fat 'cos you tend to retain a lota water.Good Luck,Bro!!
I second that sust is not the best choice for this. Propionate or enanthate would be best. Propionate taken ED will give you a very stable blood concentration and great results. If you were to use sust, the deconate ester will be around for a long time and your alternating on and off plan wouldn’t serve much purpose.
