This was your first cycle, and no one has a perfect first cycle. There is always something you will regret or wish you did differently. So dont give up just yet. There are much better drugs out there than hdrol and there are still gains to be made [what you have lost]. You seem to have the right idea, starting off with clen and cutting down that extra bf is a great start to see how much lean mass you actually lost, and what it will take to gain it back. Short oral cycles, your hdrol cycle, are the hardest cycles to try to 'keep your gains'.
This is what I would recommend.
Weeks 1-6 Cutting
Clen Weeks 1-2 ON, 3-4 OFF, 4-6 ON
GW-501615 20mg ED 1 hour Preworkout
S-4 Weeks 2-6 75mg split 3x daily. 25mg in the morning, 25mg mid day, 25mg preworkout. Weekends OFF
For the first 6 weeks, this should be done in a deficit, [obviously] and your diet will be more important than ever at this point as it will lay the path for your long term results[preserving what muscle you have left is key]. But dieting for 6 weeks using this protocol you should have no problems getting lean again in this time frame [maybe even sooner]. After you reach an optimal level of bodyfat we will be in a better position to gain muscle while staying lean. I would try this
Recomp Weeks 7-15
Ostarine 25mg ED taken in the morning
Creatine ED, you will see much greater benefits from creatine while stacked with osta.
GW-501615 20mg ED 1 hour Preworkout
For your recomp you will need to be in a caloric surplus in order to actually build some muscle, but you need to be hitting the cardio hard as well to prevent fat gain. 8 weeks isnt a very long time to see significant results from a recomp, so you have two options from here. You can continue to run the osta for as long as you see good results, but eventually you will stop and need to pct. Sarms are very easy to recover from and dont suppress you as nearly as hard as any AAS. While your nolva pct was definitely lacking for your hdrol cycle, running that exact same pct for this cycle would be more than enough to not only fully recover but actually KEEP your muscle, as the gains from sarms are much easier to keep than a pro-steriod or hormone.
OR
You can just make this a bridge into your next cycle, I wouldnt recommend anymore orals only though just due to your past experience with them was not optimal. If you do plan to run another AAS or prohormone make sure you have your entire cycle, pct, and next bridge preplanned before you start the cycle.
The practice of 'cycling' is very similar to blast and cruise, in the since that you are never really 'off' its just a never ending cycle of hormones and drugs followed by a pct, which is really just a hormonal 'boost' that is usually followed by a crash [no matter how small or great] which is why you need a bridge that doesnt suppress your natural testosterone but help you maintain your strength until your body has reached a level of homeostasis and you can maintain your strength naturally, or jump on another cycle afterwords.
