I also have a couple of hundred dbol, but I hardly use them, they cause so much water retention for me. I prefer it's East german sister, Turinabol, but I like to throw in the odd dbol before big workouts. The extra water lets me bounce those weights with impunity.
You have everything for a decent, cheap safe cycle now. 31 is a good age to start this stuff, you are a proper man, and have earned the right to make grown up decisions. Your joints and tendons have had a few good years of training. Also, you will enjoy the testosterone, it's like being a teenager again.
If it was me, I would take two 1ml test injections per week, for however many weeks you have test.That way, each butt cheek only gets one jab per week. The first couple ache, then you get better at them, and your injection sites stop complaining.
Start off with 20mg per day of Dbol in the first few days, and see how bad the estrogenic effects are for you. If the pills can be split in two, I would do this and spread the dose out through the day. Up the dose if it suits you. Try not to use the Nolva yet unless you get itchy nips - save as much as you can for PCT.
Sustanon has a bit of short ester in it, so will only take about 2 to 3 weeks before it kicks in (4 to 6 jabs). Most of the cycle will be just test. After your last injection, start the superdrol, which is quite a dry steroid, and run it for 3 weeks until you start taking Nolva and / or clomid for PCT.
When you are running your PCT, you will feel a bit run down, and lose some weight (which was water). Keep training! (but just enough to get a muscle pump) Now is the time to throw in all those non-hormonal supplements, like creatine etc.
That's just me, though. Its a bit like the classic test cycle with dbol kickstart, and winstrol/ anavar tailoff (only with superdrol instead). It sounds like quite a cool, cheap safe cycle. Good luck with it!
The superdrol will help to solidify those watery muscles, and consolidate your growth.
You will learn a lot from it, put on lots of muscle, and know exactly what you want next time. You will have a lot of dbols left over for next time. If you buy arimadex, you will be able to run a bigger dose of dbol in future without becoming a moon-faced bag of water with moobs. the arimadex will stop it forming estrogen, making it work like Tbol.
