Hi,
well you are quite young and that was a bit of a hexy first cycle, not what I would have recommended however after doing dbol and test you're not going to want to expect anything less which is a bit of a shame.
the general rule is Time on cycle plus PCT = Time off so for instance you ran you're cycle for 12 weeks, and you are running PCT for 4 weeks thats a total of 16weeks that you need you're body to rest and recover. though I always allow an extra 2+ weeks off for your body to gather itself, the less time you leave inbetween cycles the less effective the next cycle will be.
(this is an idea, an answer to your question not what I recommend) If you don't mind the bloat and you just want to get bigger and stronger I'd suggest taking Anadrol however this is quite liver toxic so you will need to take N2Guard with it and I would suggest Test Sustanon, this is going to give you some real great gains, will make you bigger than dbol and test e however you will have a little more water bloat which you need to be aware of. I would suggest running HCGenerate (pct and during) and Unleashed/ Post cycle as you are now for PCT..
However keep in mind that is the answer to your question though I would not recommend doing such a big cycle for your second cycle, if you can handle it maybe run Test Suspension, though this is everyday injections this is going to be a healthier option over running Anadrol and Test Sustanon, and still going to give you some amazing gains!
