dbol will give you bloat so you might as well use 50mg/day week 1-4 or not use it at all (my opinion).
Quality NPP shouldn't give you pip (in my experience).
Quality Sustanon also shouldn't give you pip.
Dutasteride will help with DHT but if you're prone to MPB I would suggest not using AAS.
You can back load an insulin syringe and 1" should be enough for delts, pecs even triceps.
Just don't be impatient. It takes a while to push the oil through a 27 or 29ga needle.
Is this your first cycle?
I hope not at ht e doses you're going to run.
